OF THE IMPEDIMENT OF AFFINITY (ELEVEN ARTICLES)


   We must consider next the impediment of affinity. Under this head there are eleven points of inquiry:

    (1) Whether affinity results from matrimony?

    (2) Whether it remains after the death of husband or wife?

    (3) Whether it is caused through unlawful intercourse?

    (4) Whether it arises from a betrothal?

    (5) Whether affinity is caused through affinity?

    (6) Whether affinity is an impediment to marriage?

    (7) Whether affinity in itself admits of degrees?

    (8) Whether its degrees extend as far as the degrees of consanguinity?

    (9) Whether marriages of persons related to one another by consanguinity or affinity should always be dissolved by divorce?

    (10) Whether the process for the dissolution of like marriages should always be by way of accusation?

    (11) Whether witnesses should be called in such a case?

Whether a person contracts affinity through the marriage of a blood-relation?


  Objection 1: It would seem that a person does not contract affinity through the marriage of a blood-relation. For "the cause of a thing being so is yet more so." Now the wife is not connected with her husband's kindred except by reason of the husband. Since then she does not contract affinity with her husband, neither does she contract it with her husband's kindred.

  Objection 2: Further, if certain things be separate from one another and something be connected with one of them, it does not follow that it is connected with the other. Now a person's blood relations are separate from one another. Therefore it does not follow, if a certain woman be married to a certain man, that she is therefore connected with all his kindred.

  Objection 3: Further, relations result from certain things being united together. Now the kindred of the husband do not become united together by the fact of his taking a wife. Therefore they do not acquire any relationship of affinity.

  On the contrary, Husband and wife are made one flesh. Therefore if the husband is related in the flesh to all his kindred, for the same reason his wife will be related to them all.

   Further, this is proved by the authorities quoted in the text (Sent. iv, D, 41).

  I answer that, A certain natural friendship is founded on natural fellowship. Now natural fellowship, according to the Philosopher (Ethic. viii, 12), arises in two ways; first, from carnal procreation; secondly, from connection with orderly carnal procreation, wherefore he says (Ethic. viii, 12) that the friendship of a husband towards his wife is natural. Consequently even as a person through being connected with another by carnal procreation is bound to him by a tie of natural friendship, so does one person become connected with another through carnal intercourse. But there is a difference in this, that one who is connected with another through carnal procreation, as a son with his father, shares in the same common stock and blood, so that a son is connected with his father's kindred by the same kind of tie as the father was, the tie, namely of consanguinity, albeit in a different degree on account of his being more distant from the stock: whereas one who is connected with another through carnal intercourse does not share in the same stock, but is as it were an extraneous addition thereto: whence arises another kind of tie known by the name of "affinity." This is expressed in the verse:

   Marriage makes a new kind of connection,

   While birth makes a new degree, because, to wit, the person begotten is in the same kind of relationship, but in a different degree, whereas through carnal intercourse he enters into a new kind of relationship.

  Reply to Objection 1: Although a cause is more potent than its effect, it does not always follow that the same name is applicable to the cause as to the effect, because sometimes that which is in the effect, is found in the cause not in the same but in a higher way; wherefore it is not applicable to both cause and effect under the same name or under the same aspect, as is the case with all equivocal effective causes. Thus, then, the union of husband and wife is stronger than the union of the wife with her husband's kindred, and yet it ought not to be named affinity, but matrimony which is a kind of unity; even as a man is identical with himself, but not with his kinsman.

  Reply to Objection 2: Blood-relations are in a way separate, and in a way connected: and it happens in respect of their connection that a person who is connected with one of them is in some way connected with all of them. But on account of their separation and distance from one another it happens that a person who is connected with one of them in one way is connected with another in another way, either as to the kind of connection or as to the degree.

  Reply to Objection 3: Further, a relation results sometimes from a movement in each extreme, for instance fatherhood and sonship, and a relation of this kind is really in both extremes. Sometimes it results from the movement of one only, and this happens in two ways. In one way when a relation results from the movement of one extreme without any movement previous or concomitant of the other extreme; as in the Creator and the creature, the sensible and the sense, knowledge and the knowable object: and then the relation is in one extreme really and in the other logically only. In another way when the relation results from the movement of one extreme without any concomitant movement, but not without a previous movement of the other; thus there results equality between two men by the increase of one, without the other either increasing or decreasing then, although previously he reached his actual quantity by some movement or change, so that this relation is founded really in both extremes. It is the same with consanguinity and affinity, because the relation of brotherhood which results in a grown child on the birth of a boy, is caused without any movement of the former's at the time, but by virtue of that previous movement of his wherein he was begotten; wherefore at the time it happens that there results in him the aforesaid relation through the movement of another. Likewise because this man descends through his own birth from the same stock as the husband, there results in him affinity with the latter's wife, without any new change in him.

Whether affinity remains after the death of husband or wife?


  Objection 1: It would seem that affinity does not remain after the death of husband or wife, between the blood-relations of husband and wife or "vice versa." Because if the cause cease the effect ceases. Now the cause of affinity was the marriage, which ceases after the husband's death, since then "the woman . . . is loosed from the law of the husband" (Rm. 7:2). Therefore the aforesaid affinity ceases also.

  Objection 2: Further, consanguinity is the cause of affinity. Now the consanguinity of the husband with his blood-relations ceases at his death. Therefore, the wife's affinity with them ceases also.

  On the contrary, Affinity is caused by consanguinity. Now consanguinity binds persons together for all time as long as they live. Therefore affinity does so also: and consequently affinity (between two persons) is not dissolved through the dissolution of the marriage by the death of a third person.

  I answer that, A relation ceases in two ways: in one way through the corruption of its subject, in another way by the removal of its cause; thus likeness ceases when one of the like subjects dies, or when the quality that caused the likeness is removed. Now there are certain relations which have for their cause an action, or a passion or movement (Metaph. v, 20): and some of these are caused by movement, through something being moved actually; such is the relation between mover and moved: some of them are caused through something being adapted to movement, for instance the relations between the motive power and the movable, or between master and servant; and some of them result from something, having been moved previously, such as the relation between father and son, for the relation between them is caused not by (the con) being begotten now, but by his having been begotten. Now aptitude for movement and for being moved is transitory; whereas the fact of having been moved is everlasting, since what has been never ceases having been. Consequently fatherhood and sonship are never dissolved through the removal of the cause, but only through the corruption of the subject, that is of one of the subjects. The same applies to affinity, for this is caused by certain persons having been joined together not by their being actually joined. Wherefore it is not done away, as long as the persons between whom affinity has been contracted survive, although the person die through whom it was contracted.

  Reply to Objection 1: The marriage tie causes affinity not only by reason of actual union, but also by reason of the union having been effected in the past.

  Reply to Objection 2: Consanguinity is not the chief cause of affinity, but union with a blood-relation, not only because that union is now, but because it has been. Hence the argument does not prove.

Whether unlawful intercourse causes affinity?


  Objection 1: It would seem that unlawful intercourse does not cause affinity. For affinity is an honorable thing. Now honorable things do not result from that which is dishonorable. Therefore affinity cannot be caused by a dishonorable intercourse.

  Objection 2: Further, where there is consanguinity there cannot be affinity; since affinity is a relationship between persons that results from carnal intercourse and is altogether void of blood-relationship. Now if unlawful intercourse were a cause of affinity, it would sometimes happen that a man would contract affinity with his blood-relations and with himself: for instance when a man is guilty of incest with a blood-relation. Therefore affinity is not caused by unlawful intercourse.

  Objection 3: Further, unlawful intercourse is according to nature or against nature. Now affinity is not caused by unnatural unlawful intercourse as decided by law (can. Extraordinaria, xxxv, qu. 2,3). Therefore it is not caused only by unlawful intercourse according to nature.

  On the contrary, He who is joined to a harlot is made one body (1 Cor. 6:16). Now this is the reason why marriage caused affinity. Therefore unlawful intercourse does so for the same reason.

   Further, carnal intercourse is the cause of affinity, as shown by the definition of affinity, which definition is as follows: Affinity is the relationship of persons which results from carnal intercourse and is altogether void of blood-relationship. But there is carnal copulation even in unlawful intercourse. Therefore unlawful intercourse causes affinity.

  I answer that, According to the Philosopher (Ethic. viii, 12) the union of husband and wife is said to be natural chiefly on account of the procreation of offspring, and secondly on account of the community of works: the former of which belongs to marriage by reason of carnal copulation, and the latter, in so far as marriage is a partnership directed to a common life. Now the former is to be found in every carnal union where there is a mingling of seeds, since such a union may be productive of offspring, but the latter may be wanting. Consequently since marriage caused affinity, in so far as it was a carnal mingling, it follows that also an unlawful intercourse causes affinity in so far as it has something of natural copulation.

  Reply to Objection 1: In an unlawful intercourse there is something natural which is common to fornication and marriage, and in this respect it causes affinity. There is also something which is inordinate whereby it differs from marriage, and in this respect it does not cause affinity. Hence affinity remains honorable, although its cause is in a way dishonorable.

  Reply to Objection 2: There is no reason why diverse relations should not be in the same subject by reason of different things. Consequently there can be affinity and consanguinity between two persons, not only on account of unlawful but also on account of lawful intercourse: for instance if a blood-relation of mine on my father's side marries a blood-relation of mine on my mother's side. Hence in the above definition the words "which is altogether void of blood-relationship" apply to affinity as such. Nor does it follow that a man by having intercourse with his blood-relation contracts affinity with himself, since affinity, like consanguinity, requires diversity of subjects, as likeness does.

  Reply to Objection 3: In unnatural copulation there is no mingling of seeds that makes generation possible: wherefore a like intercourse does not cause affinity.

Whether affinity is caused by betrothal?


  Objection 1: It would seem that affinity cannot be caused by betrothal. For affinity is a lasting tie: whereas a betrothal is sometimes broken off. Therefore it cannot cause affinity.

  Objection 2: Further if the hymen be penetrated without the deed being consummated, affinity is not contracted. Yet this is much more akin to carnal intercourse than a betrothal. Therefore betrothal does not cause affinity.

  Objection 3: Further, betrothal is nothing but a promise of future marriage. Now sometimes there is a promise of future marriage without affinity being contracted, for instance if it take place before the age of seven years; or if a man having a perpetual impediment of impotence promise a woman future marriage; or if a like promise be made between persons to whom marriage is rendered unlawful by a vow; or in any other way whatever. Therefore betrothal cannot cause affinity.

  On the contrary, Pope Alexander (cap. Ad audiendem, De spons. et matrim.) forbade a certain woman to marry a certain man, because she had been betrothed to his brother. Now this would not be the case unless affinity were contracted by betrothal. Therefore, etc.

  I answer that, Just as a betrothal has not the conditions of a perfect marriage, but is a preparation for marriage, so betrothal causes not affinity as marriage does, but something like affinity. This is called "the justice of public honesty," which is an impediment to marriage even as affinity and consanguinity are, and according to the same degrees, and is defined thus: "The justice of public honesty is a relationship arising out of betrothal, and derives its force from ecclesiastical institution by reason of its honesty." This indicates the reason of its name as well as its cause, namely that this relationship was instituted by the Church on account of its honesty.

  Reply to Objection 1: Betrothal, by reason not of itself but of the end to which it is directed, causes this kind of affinity known as "the justice of public honesty": wherefore just as marriage is a lasting tie, so is the aforesaid kind of affinity.

  Reply to Objection 2: In carnal intercourse man and woman become one flesh by the mingling of seeds. Wherefore it is not every invasion or penetration of the hymen that causes affinity to be contracted, but only such as is followed by a mingling of seeds. But marriage causes affinity not only on account of carnal intercourse, but also by reason of the conjugal fellowship, in respect of which also marriage is according to nature. Consequently affinity results from the marriage contract itself expressed in words of the present and before its consummation, and in like manner there results from betrothal, which is a promise of conjugal fellowship, something akin to affinity, namely the justice of public honesty.

  Reply to Objection 3: All those impediments which void a betrothal prevent affinity being contracted through a promise of marriage. Hence whether he who actually promises marriage be lacking in age, or be under a solemn vow of continence or any like impediment, no affinity nor anything akin to it results because the betrothal is void. If however, a minor, laboring under insensibility or malefice, having a perpetual impediment, is betrothed before the age of puberty and after the age of seven years, with a woman who is of age, from such a contract there results the impediment called "justice of public honesty," because at the time the impediment was not actual, since at that age the boy who is insensible is equally impotent in respect of the act in question.

Whether affinity is a cause of affinity?


  Objection 1: It would seem that affinity also is a cause of affinity. For Pope Julius I says (cap. Contradicimus 35, qu. iii): "No man may marry his wife's surviving blood-relation": and it is said in the next chapter (cap. Porro duorum) that "the wives of two cousins are forbidden to marry, one after the other, the same husband." But this is only on account of affinity being contracted through union with a person related by affinity. Therefore affinity is a cause of affinity.

  Objection 2: Further, carnal intercourse makes persons akin even as carnal procreation, since the degrees of affinity and consanguinity are reckoned equally. But consanguinity causes affinity. Therefore affinity does also.

  Objection 3: Further, things that are the same with one and the same are the same with one another. But the wife contracts the same relations with all her husband's kindred. Therefore all her husband's kindred are made one with all who are related by affinity to the wife, and thus affinity is the cause of affinity.

  Objection 4: On the contrary, If affinity is caused by affinity a man who has connection with two women can marry neither of them, because then the one would be related to the other by affinity. But this is false. Therefore affinity does not cause affinity.

  Objection 5: Further, if affinity arose out of affinity a man by marrying another man's widow would contract affinity with all her first husband's kindred, since she is related to them by affinity. But this cannot be the case because he would become especially related by affinity to her deceased husband. Therefore, etc.

  Objection 6: Further, consanguinity is a stronger tie than affinity. But the blood-relations of the wife do not become blood-relations of the husband. Much less, therefore, does affinity to the wife cause affinity to her blood-relations, and thus the same conclusion follows.

  I answer that, There are two ways in which one thing proceeds from another: in one way a thing proceeds from another in likeness of species, as a man is begotten of a man: in another way one thing proceeds from another, not in likeness of species; and this process is always towards a lower species, as instanced in all equivocal agents. The first kind of procession, however often it be repeated, the same species always remains: thus if one man be begotten of another by an act of the generative power, of this man also another man will be begotten, and so on. But the second kind of procession, just as in the first instance it produces another species, so it makes another species as often as it is repeated. Thus by movement from a point there proceeds a line and not a point, because a point by being moved makes a line; and from a line moved lineally, there proceeds not a line but a surface, and from a surface a body, and in this way the procession can go no further. Now in the procession of kinship we find two kinds whereby this tie is caused: one is by carnal procreation, and this always produces the same species of relationship; the other is by the marriage union, and this produces a different kind of relationship from the beginning: thus it is clear that a married woman is related to her husband's blood-relations not by blood but by affinity. Wherefore if this kind of process be repeated, the result will be not affinity but another kind of relationship; and consequently a married party contracts with the affines of the other party a relation not of affinity but of some other kind which is called affinity of the second kind. And again if a person through marriage contracts relationship with an affine of the second kind, it will not be affinity of the second kind, but of a third kind, as indicated in the verse quoted above (Article [1]). Formerly these two kinds were included in the prohibition, under the head of the justice of public honesty rather than under the head of affinity, because they fall short of true affinity, in the same way as the relationship arising out of betrothal. Now however they have ceased to be included in the prohibition, which now refers only to the first kind of affinity in which true affinity consists.

  Reply to Objection 1: A husband contracts affinity of the first kind with his wife's male blood-relation, and affinity of the second kind with the latter's wife: wherefore if the latter man dies the former cannot marry his widow on account of the second kind of affinity. Again if a man A marry a widow B, C, a relation of her former husband being connected with B by the first kind of affinity, contracts affinity of the second kind with her husband A; and D, the wife of this relation C being connected, by affinity of the second kind, with B, this man's wife contracts affinity of the third kind with her husband A. And since the third kind of affinity was included in the prohibition on account of a certain honesty more than by reason of affinity, the canon (cap. Porro duorum 35, qu. iii) says: "The justice of public honesty forbids the wives of two cousins to be married to the same man, the one after the other." But this prohibition is done away with.

  Reply to Objection 2: Although carnal intercourse is a cause of people being connected with one another, it is not the same kind of connection.

  Reply to Objection 3: The wife contracts the same connection with her husband's relatives as to the degree but not as to the kind of connection.

   Since however the arguments in the contrary sense would seem to show that no tie is caused by affinity, we must reply to them lest the time-honored prohibition of the Church seem unreasonable.

  Reply to Objection 4: As stated above, a woman does not contract affinity of the first kind with the man to whom she is united in the flesh, wherefore she does not contract affinity of the second kind with a woman known by the same man; and consequently if a man marry one of these women, the other does not contract affinity of the third kind with him. And so the laws of bygone times did not forbid the same man to marry successively two women known by one man.

  Reply to Objection 5: As a man is not connected with his wife by affinity of the first kind, so he does not contract affinity of the second kind with the second husband of the same wife. Wherefore the argument does not prove.

  Reply to Objection 6: One person is not connected with me through another, except they be connected together. Hence through a woman who is affine to me, no person becomes connected with me, except such as is connected with her. Now this cannot be except through carnal procreation from her, or through connection with her by marriage: and according to the olden legislation, I contracted some kind of connection through her in both ways: because her son even by another husband becomes affine to me in the same kind and in a different degree of affinity, as appears from the rule given above: and again her second husband becomes affine to me in the second kind of affinity. But her other blood-relations are not connected with him, but she is connected with them, either as with father or mother, inasmuch as she descends from them, or, as with her brothers, as proceeding from the same principle; wherefore the brother or father of my affine does not become affine to me in any kind of affinity.

Whether affinity is an impediment to marriage?


  Objection 1: It would seem that affinity is not an impediment to marriage. For nothing is an impediment to marriage except what is contrary thereto. But affinity is not contrary to marriage since it is caused by it. Therefore it is not an impediment to marriage.

  Objection 2: Further, by marriage the wife becomes a possession of the husband. Now the husband's kindred inherit his possessions after his death. Therefore they can succeed to his wife, although she is affine to them, as shown above (Article [5]). Therefore affinity is not an impediment to marriage.

  On the contrary, It is written (Lev. 18:8): "Thou shalt not uncover the nakedness of thy father's wife." Now she is only affine. Therefore affinity is an impediment to marriage.

  I answer that, Affinity that precedes marriage hinders marriage being contracted and voids the contract, for the same reason as consanguinity. For just as there is a certain need for blood-relations to live together, so is there for those who are connected by affinity: and just as there is a tie of friendship between blood-relations, so is there between those who are affine to one another. If, however, affinity supervene to matrimony, it cannot void the marriage, as stated above (Question [50], Article [7]).

  Reply to Objection 1: Affinity is not contrary to the marriage which causes it, but to a marriage being contracted with an affine, in so far as the latter would hinder the extension of friendship and the curbing of concupiscence, which are sought in marriage.

  Reply to Objection 2: The husband's possessions do not become one with him as the wife is made one flesh with him. Wherefore just as consanguinity is an impediment to marriage or union with the husband according to the flesh, so is one forbidden to marry the husband's wife.

Whether affinity in itself admits of degrees?


  Objection 1: It would seem that affinity in itself admits of degrees. For any kind of propinquity can itself be the subject of degrees. Now affinity is a kind of propinquity. Therefore it has degrees in itself apart from the degrees of consanguinity by which it is caused.

  Objection 2: Further, it is stated in the text (Sent. iv, D, 41) that the child of a second marriage could not take a consort from within the degrees of affinity of the first husband. But this would not be the case unless the son of an affine were also affine. Therefore affinity like consanguinity admits itself of degrees.

  On the contrary, Affinity is caused by consanguinity. Therefore all the degrees of affinity are caused by the degrees of consanguinity: and so it has no degrees of itself.

  I answer that, A thing does not of itself admit of being divided except in reference to something belonging to it by reason of its genus: thus animal is divided into rational and irrational and not into white and black. Now carnal procreation has a direct relation to consanguinity, because the tie of consanguinity is immediately contracted through it; whereas it has no relation to affinity except through consanguinity which is the latter's cause. Wherefore since the degrees of relationship are distinguished in reference to carnal procreation, the distinction of degrees is directly and immediately referable to consanguinity, and to affinity through consanguinity. Hence the general rule in seeking the degrees of affinity is that in whatever degree of consanguinity I am related to the husband, in that same degree of affinity I am related to the wife.

  Reply to Objection 1: The degrees in propinquity of relationship can only be taken in reference to ascent and descent of propagation, to which affinity is compared only through consanguinity. Wherefore affinity has no direct degrees, but derives them according to the degrees of consanguinity.

  Reply to Objection 2: Formerly it used to be said that the son of my affine by a second marriage was affine to me, not directly but accidentally as it were: wherefore he was forbidden to marry on account of the justice of public honesty rather than affinity. And for this reason this prohibition is now revoked.

Whether the degrees of affinity extend in the same way as the degrees of consanguinity?


  Objection 1: It would seem that the degrees of affinity do not extend in the same way as the degrees of consanguinity. For the tie of affinity is less strong than the tie of consanguinity, since affinity arises from consanguinity in diversity of species, as from an equivocal cause. Now the stronger the tie the longer it lasts. Therefore the tie of affinity does not last to the same number of degrees as consanguinity.

  Objection 2: Further, human law should imitate Divine law. Now according to the Divine law certain degrees of consanguinity were forbidden, in which degrees affinity was not an impediment to marriage: as instanced in a brother's wife whom a man could marry although he could not marry her sister. Therefore now too the prohibition of affinity and consanguinity should not extend to the same degrees.

  On the contrary, A woman is connected with me by affinity from the very fact that she is married to a blood-relation of mine. Therefore in whatever degree her husband is related to me by blood she is related to me in that same degree by affinity: and so the degrees of affinity should be reckoned in the same number as the degrees of consanguinity.

  I answer that, Since the degrees of affinity are reckoned according to the degrees of consanguinity, the degrees of affinity must needs be the same in number as those of consanguinity. Nevertheless, affinity being a lesser tie than consanguinity, both formerly and now, a dispensation is more easily granted in the more remote degrees of affinity than in the remote degrees of consanguinity.

  Reply to Objection 1: The fact that the tie of affinity is less than the tie of consanguinity causes a difference in the kind of relationship but not in the degrees. Hence this argument is not to the point.

  Reply to Objection 2: A man could not take his deceased brother's wife except, in the case when the latter died without issue, in order to raise up seed to his brother. This was requisite at a time when religious worship was propagated by means of the propagation of the flesh, which is not the case now. Hence it is clear that he did not marry her in his own person as it were, but as supplying the place of his brother.

Whether a marriage contracted by persons with the degrees of affinity or consanguinity should always be annulled?


  Objection 1: It would seem that a marriage contracted by persons within the degrees of affinity or consanguinity ought not always to be annulled by divorce. For "what God hath joined together let no man put asunder" (Mt. 19:6). Since then it is understood that what the Church does God does, and since the Church sometimes through ignorance joins such persons together, it would seem that if subsequently this came to knowledge they ought not to be separated.

  Objection 2: Further, the tie of marriage is less onerous than the tie of ownership. Now after a long time a man may acquire by prescription the ownership of a thing of which he was not the owner. Therefore by length of time a marriage becomes good in law, although it was not so before.

  Objection 3: Further, of like things we judge alike. Now if a marriage ought to be annulled on account of consanguinity, in the case when two brothers marry two sisters, if one be separated on account of consanguinity, the other ought to be separated for the same reason. and yet this is not seemly. Therefore a marriage ought not to be annulled on account of affinity or consanguinity.

  On the contrary, Consanguinity and affinity forbid the contracting of a marriage and void the contract. Therefore if affinity or consanguinity be proved, the parties should be separated even though they have actually contracted marriage.

  I answer that, Since all copulation apart from lawful marriage is a mortal sin, which the Church uses all her endeavors to prevent, it belongs to her to separate those between whom there cannot be valid marriage, especially those related by blood or by affinity, who cannot without incest be united in the flesh.

  Reply to Objection 1: Although the Church is upheld by God's gift and authority, yet in so far as she is an assembly of men there results in her acts something of human frailty which is not Divine. Therefore a union effected in the presence of the Church who is ignorant of an impediment is not indissoluble by Divine authority, but is brought about contrary to Divine authority through man's error, which being an error of fact excuses from sin, as long as it remains. Hence when the impediment comes to the knowledge of the Church, she ought to sever the aforesaid union.

  Reply to Objection 2: That which cannot be done without sin is not ratified by any prescription, for as Innocent III says (Conc. Later. iv, can. 50: cap. Non debent, De consang. et affinit.), "length of time does not diminish sin but increases it": nor can it in any way legitimize a marriage which could not take place between unlawful persons.

  Reply to Objection 3: In contentious suits between two persons the verdict does not prejudice a third party, wherefore although the one brother's marriage with the one sister is annulled on account of consanguinity, the Church does not therefore annul the other marriage against which no action is taken. Yet in the tribunal of the conscience the other brother ought not on this account always to be bound to put away his wife, because such accusations frequently proceed from ill-will, and are proved by false witnesses. Hence he is not bound to form his conscience on what has been done about the other marriage: but seemingly one ought to draw a distinction, because either he has certain knowledge of the impediment of his marriage, or he has an opinion about it, or he has neither. In the first case, he can neither seek nor pay the debt, in the second, he must pay, but not ask, in the third he can both pay and ask.

Whether it is necessary to proceed by way of accusation for the annulment of a marriage contracted by persons related to each other by affinity or consanguinity?


  Objection 1: It would seem that one ought not to proceed by way of accusation in order to sever a marriage contracted between persons related by affinity or consanguinity. Because accusation is preceded by inscription* whereby a man binds himself to suffer the punishment of retaliation, if he fail to prove his accusation. [*The accuser was bound by Roman Law to endorse (se inscribere) the writ of accusation; Cf. SS, Question [33], Article [7]]. But this is not required when a matrimonial separation is at issue. Therefore accusation has no place then. Aquin.: SMT XP Question [55] Article [10] Obj. 2 Para. 1/1 OBJ 2: Further, in a matrimonial lawsuit only the relatives are heard, as stated in the text (Sent. iv, D, 41). But in accusations even strangers are heard. Therefore in a suit for matrimonial separation the process is not by way of accusation.

  Objection 3: Further, if a marriage ought to be denounced this should be done especially where it is least difficult to sever the tie. Now this is when only the betrothal has been contracted, and then it is not the marriage that is denounced. Therefore accusation should never take place at any other time.

  Objection 4: Further, a man is not prevented from accusing by the fact that he does not accuse at once. But this happens in marriage, for if he was silent at first when the marriage was being contracted, he cannot denounce the marriage afterwards without laying himself open to suspicion. Therefore, etc.

  On the contrary, Whatever is unlawful can be denounced. But the marriage of relatives by affinity and consanguinity is unlawful. Therefore it can be denounced.

  I answer that, Accusation is instituted lest the guilty be tolerated as though they were innocent. Now just as it happens through ignorance of fact that a guilty man is reputed innocent, so it happens through ignorance of a circumstance that a certain fact is deemed lawful whereas it is unlawful. Wherefore just as a man is sometimes accused, so is a fact sometimes an object of accusation. It is in this way that a marriage is denounced, when through ignorance of an impediment it is deemed lawful, whereas it is unlawful.

  Reply to Objection 1: The punishment of retaliation takes place when a person is accused of a crime, because then action is taken that he may be punished. But when it is a deed that is accused, action is taken not for the punishment of the doer, but in order to prevent what is unlawful. Hence in a matrimonial suit the accuser does not bind himself to a punishment. Moreover, the accusation may be made either in words or in writing, provided the person who denounces the marriage denounced, and the impediment for which it is denounced, be expressed.

  Reply to Objection 2: Strangers cannot know of the consanguinity except from the relatives, since these know with greater probability. Hence when these are silent, a stranger is liable to be suspected of acting from ill-will unless he wish the relatives to prove his assertion. Wherefore a stranger is debarred from accusing when there are relatives who are silent, and by whom he cannot prove his accusation. On the other hand the relatives, however nearly related they be, are not debarred from accusing, when the marriage is denounced on account of a perpetual impediment, which prevents the contracting of the marriage and voids the contract. When, however, the accusation is based on a denial of the contract having taken place, the parents should be debarred from witnessing as being liable to suspicion, except those of the party that is inferior in rank and wealth, for they, one is inclined to think, would be willing for the marriage to stand.

  Reply to Objection 3: If the marriage is not yet contracted and there is only a betrothal, there can be no accusation, for what is not, cannot be accused. But the impediment can be denounced lest the marriage be contracted.

  Reply to Objection 4: He who is silent at first is sometimes heard afterwards if he wish to denounce the marriage, and sometimes he is repulsed. This is made clear by the Decretal (cap. Cum in tua, De his qui matrim. accus. possunt.) which runs as follows: "If an accuser present himself after the marriage has been contracted, since he did not declare himself when according to custom, the banns were published in church, we may rightly ask whether he should be allowed to voice his accusation. In this matter we deem that a distinction should be made, so that if he who lodges information against persons already married was absent from the diocese at the time of the aforesaid publication, or if for some other reason this could not come to his knowledge, for instance if through exceeding stress of weakness and fever he was not in possession of his faculties, or was of so tender years as to be too young to understand such matters, or if he were hindered by some other lawful cause, his accusation should be heard. otherwise without doubt he should be repulsed as open to suspicion, unless he swear that the information lodged by him came to his knowledge subsequently and that he is not moved by ill-will to make his accusation."

Article: 11  [<< | >>]


Whether in a suit of this kind one should proceed by hearing witnesses in the same way as in other suits?


  Objection 1: It would seem that in such a suit one ought not to proceed by hearing witnesses, in the same way as in other suits where any witnesses may be called provided they be unexceptionable. But here strangers are not admitted, although they be unexceptionable. Therefore, etc.

  Objection 2: Further, witnesses who are suspected of private hatred or love are debarred from giving evidence. Now relatives are especially open to suspicion of love for one party, and hatred for the other. Therefore their evidence should not be taken.

  Objection 3: Further, marriage is a more favorable suit than those others in which purely corporeal questions are at stake. Now in these the same person cannot be both accuser and witness. Neither therefore can this be in a matrimonial suit; and so it would appear that it is not right to proceed by hearing witnesses in a suit of this kind.

  On the contrary, Witnesses are called in a suit in order to give the judge evidence concerning matters of doubt. Now evidence should be afforded the judge in this suit as in other suits, since he must not pronounce a hasty judgment on what is not proven. Therefore here as in other lawsuits witnesses should be called.

  I answer that, In this kind of lawsuit as in others, truth must be unveiled by witnesses: yet, as the lawyers say, there are many things peculiar to this suit; namely that "the same person can be accuser and witness; that evidence is not taken 'on oath of calumny,' since it is a quasi-spiritual lawsuit; that relatives are allowed as witnesses; that the juridical order is not perfectly observed, since if the denunciation has been made, and the suit is uncontested, the defendant may be excommunicated if contumacious; that hearsay evidence is admitted; and that witnesses may be called after the publication of the names of the witnesses." All this is in order to prevent the sin that may occur in such a union (cap. Quoties aliqui; cap. Super eo, De test. et attest.; cap. Literas, De juram. calumn.).

   This suffices for the Replies to the Objections.

pr.

Deinde considerandum est de impedimento affinitatis.

Circa quod quaeruntur undecim.

Primo: utrum affinitas ex matrimonio causetur.

Secundo: utrum maneat post mortem viri aut uxoris.

Tertio: utrum causetur ex illicito concubitu.

Quarto: utrum ex sponsalibus.

Quinto: utrum affinitas sit causa affinitatis.

Sexto: utrum affinitas matrimonium impediat.

Septimo: utrum affinitas habeat per seipsam gradus.

Octavo: utrum gradus eius extendantur sicut gradus consanguinitatis.

Nono: utrum matrimonium quod est inter consanguineos et affines, semper sit dirimendum per divortium.

Decimo: utrum ad dirimendum tale matrimonium sit procedendum per viam accusationis.

Undecimo: utrum in tali causa sit procedendum per testes.

a. 1 arg. 1

Ad primum sic proceditur. Videtur quod ex matrimonio consanguinei affinitas non causetur. Quia propter quod unumquodque, illud magis. Sed mulier ducta in matrimonium non coniungitur alicui de consanguinitate viri nisi ratione viri. Cum ergo non fiat viro affinis, nec alicui consanguineorum viri affinis erit.

a. 1 arg. 2

Praeterea, eorum quae sunt ab invicem separata, si urii aliquid coniungitur, non oportet propter hoc quod sit alteri coniunctum. Sed consanguinei iam sunt ab invicem separati. Ergo non oportet quod, si aliqua mulier coniungatur alicui viro, quod propter hoc coniungatur omnibus consanguineis eius per affinitatem.

a. 1 arg. 3

Praeterea, relationes ex aliquibus unitionibus innascuntur. Sed nulla unitio fit in consanguineis viri per hoc quod ille duxit uxorem. Ergo non accrescit eis affinitatis relatio.

a. 1 s. c. 1

Sed contra: Vir et uxor efficiuntur una caro. Si ergo vir secundum carnem omnibus suis consanguineis attinet, et mulier eadem ratione attinebit eisdem.
B: (Rom 5:3) [b:Rom 5:3] (Rom 5:4) [b:Rom 5:4]

a. 1 arg. 4

Praeterea, hoc patet per auctoritates in littera inductas.
B: (Ps 118) [b:Ps 118]

a. 1 co.

Respondeo dicendum quod amicitia quaedam naturalis in communicatione naturali fundatur. Naturalis autem communicatio est duobus modis, secundum Philosophum, VIII Ethic.: uno modo, per carnis propagationem; alio modo, per coniunctionem ad carnis propagationem ordinatam. Unde ipse ibidem dicit quod amicitia viri ad uxorem est naturalis. Unde, sicut persona coniuncta alteri per carnis propagationem quoddam vinculum naturalis amicitiae facit, ita si coniungatur per carnalem copulam. Sed in hoc differt, quod persona coniuncta alicui per carnis propagationem, sicut filius patri, fit particeps eiusdem radicis et sanguinis: unde eodem genere vinculi colligatur filius consanguineis patris quo pater coniungebatur, scilicet consanguinitate; quamvis secundum alium gradum, propter maiorem distantiam a radice. Sed persona coniuncta per carnalem copulam non fit particeps eiusdem radicis, sed quasi extrinsecus adiuncta. Et ideo ex hoc efficitur aliud genus vinculi, quod ‘affinitas’ dicitur. Et hoc est quod in hoc versu dicitur: mutat nupta genus, sed generata gradum: quia scilicet persona generata fit in eodem genere attinentiae, sed alio gradu; per carnalem vero copulam fit in alio genere.

a. 1 ad 1

Ad primum ergo dicendum quod, quamvis causa sit potior effectu, non tamen oportet semper quod nomen idem effectui et causae conveniat: quia quandoque illud quod est in effectu, invenitur in causa non eodem modo, sed altiori, et ideo non convenit causae et effectui per idem nomen, neque per eandem rationem; sicut patet in omnibus causis aequivoce agentibus. Et hoc modo coniunctio viri et uxoris est potior quam coniunctio uxoris ad consanguineos viri: non tamen debet dici affinitas, sed ‘matrimonium’, quod est unitas quaedam; sicut homo est sibi ipsi idem, non consanguineus.

a. 1 ad 2

Ad secundum dicendum quod consanguinei sunt quodammodo separati et quodammodo coniuncti. Et ratione coniunctionis accidit quod persona quae uni coniungitur, aliquo modo omnibus coniungatur. Sed propter separationem et distantiam accidit quod persona quae uni coniungitur uno modo, alii coniungatur alio modo, vel secundum aliud genus vel secundum alium gradum.

a. 1 ad 3

Ad tertium dicendum quod relatio quandoque innascitur ex motu utriusque extremi, sicut paternitas et filiatio. Et talis relatio est realiter in utroque.

Quandoque vero innascitur ex motu alterius tantum. Et hoc contingit dupliciter. Uno modo, quando relatio innascitur ex motu unius sine motu alterius vel praecedente vel concomitante: sicut in Creatore et creatura pateti et sensibili et sensu, et scientia et scibili. Et tunc relatio est in uno secundum rem, et in altero secundum rationem tantum. Alio modo, quando innascitur ex motu unius sine motu alterius tunc existente, non tamen sine motu praecedente: sicut aequalitas fit inter duos homines per augmentum unius, sine hoc quod alius tunc augeatur vel minuatur; sed tamen prius ad hanc quantitatem quam habet per aliquem motum vel mutationem pervenit. Et ideo in utroque extremorum talis relatio realiter fundatur.

Et similiter est de consanguinitate et affinitate. Quia relatio fraternitatis quae innascitur aliquo puero nato alicui iam provecto, causatur quidem sine motu ipsius tunc existente, sed ex motu ipsius praecedente, scilicet generationis eius: hoc enim ei accidit quod ex motu alterius sibi nunc talis relatio innascitur. Similiter ex hoc quod iste descendit per generationem propriam ab eadem radice cum viro, provenit affinitas in ipso ad uxorem sine aliqua nova mutatione ipsius.

a. 2 arg. 1

Ad secundum sic proceditur. Videtur quod affinitas non manet post mortem viri inter consanguineos viri et uxorem. Quia, cessante causa, cessat effectus. Sed causa affinitatis fuit matrimonium, quod cessat in morte viri: quia tunc solvitur mulier a lege viri, ut dicitur Rom. 7. Ergo nec affinitas praedicta manet.
B: (Jas 5:13) [b:Jas 5:13]

a. 2 arg. 2

Praeterea, consanguinitas causat affinitatem. Sed consanguinitas viri cessat per mortem ad consanguineos suos. Ergo et affinitas uxoris ad eos.
B: (Mark 9:28) [b:Mark 9:28]

a. 2 s. c. 1

Sed contra, affinitas ex consanguinitate causatur. Sed consanguinitas est perpetuum vinculum, quandiu personae vivunt inter quas est affinitas. Ergo et affinitas. Et ita non solvitur affinitas soluto matrimonio per mortem tertiae personae.
B: (Luke 11:41) [b:Luke 11:41]

a. 2 co.

Respondeo dicendum quod relatio aliqua esse desinit dupliciter: uno modo ex corruptione subiecti, alio modo ex subtractione causae; sicut similitudo esse desinit quando alter similium moritur, vel quando qualitas quae erat causa similitudinis, subtrahitur. Sunt autem quaedam relationes quae habent pro causa actionem vel passionem aut motum, ut in V Metaphys. dicitur. Quarum quaedam causantur ex motu inquantum aliquid movetur actu: sicut ipsa relatio quae est moventis et moti. Quaedam autem inquantum habent aptitudinem ad motum; sicut motivum et mobile, dominus et servus. Quaedam autem ex hoc quod aliquid prius motum est: sicut pater et filius non ex hoc quod est generari nunc, ad invicem dicuntur; sed ex hoc quod est generatum esse.

Aptitudo autem ad motum, etiam ipsum moveri transit: sed motum esse perpetuum est, quia quod factum est, nunquam desinit esse factum. Et ideo paternitas et filiatio nunquam destruuntur per destructionem causae, sed solum per corruptionem subiecti, scilicet alterutrius extremorum. Et similiter dicendum est de affinitate, quae causatur ex hoc quod aliqui coniuncti sunt, non ex hoc quod coniunguntur. Unde non dirimitur, manentibus illis personis inter quas affinitas est contracta, quamvis moriatur persona ratione cuius contracta fuit.

a. 2 ad 1

Ad primum ergo dicendum quod coniunctio matrimonii causat affinitatem non solum secundum hoc quod est actu coniungi, sed secundum hoc quod est prius coniunctum esse.

a. 2 ad 2

Ad secundum dicendum quod consanguinitas non est proxima causa affinitatis: sed coniunctio ad consanguineum, non solum quae est, sed quae fuit. Et propter hoc ratio non sequitur.

a. 3 arg. 1

Ad tertium sic proceditur. Videtur quod illicitus concubitus affinitatem non causet. Quia affinitas est quaedam res honesta. Sed res honestae non causantur ex inhonestis. Ergo ex inhonesto concubitu non potest affinitas causari.

a. 3 arg. 2

Praeterea, ubi est consanguinitas, non potest esse affinitas: quia affinitas, est proximitas personarum ex carnali copula proveniens omni carens parentela. Sed aliquando contingeret ad consanguineos et ad seipsum esse affinitatem, si illicitus concubitus affinitatem causaret: sicut quando homo carnaliter consanguineam suam incestuose cognoscit. Ergo affinitas non causatur, ex illicito concubitu.

a. 3 arg. 3

Praeterea, illicitus concubitus est secundum naturam, et contra naturam. Sed ex illicito concubitu contra naturam non causatur affinitas, ut iura determinant. Ergo nec ex illicito concubitu secundum naturam tantum.

a. 3 s. c. 1

Sed contra: Est quod adhaerens meretrici unum corpus efficitur, ut patet I Cor. 6. Sed ex hac causa matrimonium affinitatem causabat. Ergo, pari ratione, illicitus concubitus.

a. 3 arg. 4

Praeterea, carnalis copula est causa affinitatis: ut patet per definitionem affinitatis, quae est talis: affinitas est propinquitas personarum ex carnali copula proveniens omni carens parentela. Sed carnalis copula est etiam in illicito concubitu. Ergo illicitus concubitus affinitatem causat.

a. 3 co.

Respondeo dicendum quod, secundum Philosophum, in VIII Ethic., coniunctio viri et uxoris dicitur naturalis principaliter propter prolis productionem, et secundario propter operum communicationem: quorum primum pertinet ad matrimonium ratione carnalis copulae, sed secundum inquantum est quaedam societas in communem vitam. Primum autem horum est invenire in qualibet carnali copula ubi est commixtio seminum, quia ex tali copula potest proles produci: quamvis secunda desit. Et ideo, quia matrimonium affinitatem causabat secundum quod erat quaedam carnalis commixtio, etiam fornicarius concubitus affinitatem causat, inquantum habet aliquid de carnali coniunctione.

a. 3 ad 1

Ad primum ergo dicendum quod in fornicario concubitu est aliquid naturale, quod est commune fornicationi et matrimonio: et ex hac parte affinitatem causat. Aliud est ibi inordinatum, per quod a matrimonio dividitur: et ex hac parte affinitas non causatur. Unde affinitas semper honesta remanet, quamvis causa aliquo modo sit inhonesta.

a. 3 ad 2

Ad secundum dicendum quod non est inconveniens relationes ex opposito divisas eidem inesse ratione diversorum. Et ideo potest inter aliquas duas personas esse affinitas et consanguinitas, non solum per illicitum concubitum, sed etiam per licitum: sicut cum consanguineus meus ex parte patris, duxit in uxorem consanguineam meam ex parte matris. Unde, cum dicitur in definitione affinitatis inducta, omni carens parentela, intelligendum est, inquantum huiusmodi. Nec tamen sequitur quod aliquis consanguineam suam cognoscens sibi ipsi sit affinis: quia affinitas, sicut et consanguinitas, diversitatem requirit; sicut et similitudo.

a. 3 ad 3

Ad tertium dicendum quod concubitus contra naturam non habet commixtionem seminum quae possit esse causa generationis. Et ideo ex tali concubitu non causatur aliqua affinitas.

a. 4 arg. 1

Ad quartum sic proceditur. Videtur quod ex sponsalibus nulla affinitas causari possit. Quia affinitas est perpetuum vinculum. Sed sponsalia quandoque separantur. Ergo non possunt esse causa affinitatis.

a. 4 arg. 2

Praeterea, si aliquis claustrum pudoris alicuius mulieris invasit et aperuit, sed non pervenit ad operis consummationem, non contrahitur ex hoc affinitas. Sed talis est magis propinquus carnali copulae quam ille qui sponsalia contrahit. Ergo ex sponsalibus affinitas non causatur.

a. 4 arg. 3

Praeterea, in sponsalibus non fit nisi quaedam sponsio futurarum nuptiarum. Sed aliquando fit sponsio futurarum nuptiarum et ex hoc non contrahitur aliqua affinitas: sicut si fiat ante septennium, vel si aliquis habens perpetuum impedimentum tollens potentiam coeundi alicui mulieri spondeat futuras nuptias, aut si talis sponsio fiat inter personas quibus nuptiae per votum reddantur illicitae, vel alio quocumque modo. Ergo sponsalia non possunt esse causa affinitatis.

a. 4 s. c. 1

Sed contra est quod Alexander Papa prohibuit mulierem quandam cuidam viro matrimonio coniungi quia fratri suo fuerat desponsata. Quod non esset nisi per sponsalia affinitas contraheretur. Ergo, etc.

a. 4 co.

Respondeo dicendum quod, sicut sponsalia non habent perfectam rationem matrimonii sed sunt quaedam praeparatio ad matrimonium, ita ex sponsalibus non causatur affinitas sicut ex matrimonio, sed aliquid affinitati simile, quod dicitur publicae honestatis iustitia: quae impedit matrimonium sicut et affinitas et consanguinitas, secundum eosdem gradus. Et definitur sic: Publicae honestatis iustitia est propinquitas ex sponsalibus proveniens, robur trahens ex Ecclesiae institutione propter eius honestatem. Ex quo patet ratio nominis et causa: quia scilicet talis propinquitas ab Ecclesia instituta est propter honestatem.

a. 4 ad 1

Ad primum ergo dicendum quod sponsalia non ratione sui, sed ratione eius ad quod ordinantur, causant hoc genus affinitatis quod dicitur publicae honestatis iustitia. Et ideo, sicut matrimonium est perpetuum vinculum, ita et praedictus affinitatis modus.

a. 4 ad 2

Ad secundum dicendum quod vir et mulier efficiuntur in carnali copula una caro per commixtionem seminum. Unde, quantumcumque aliquis claustrum pudoris invadat vel frangat, nisi commixtio seminum sequatur, non contrahitur ex hoc affinitas. Sed matrimonium affinitatem causat non solum ratione carnalis copulae, sed etiam ratione societatis coniugalis, secundum quam etiam matrimonium naturale est. Unde et affinitas contrahitur ex ipso contractu matrimonii per verba de praesenti ante carnalem copulam. Et similiter etiam ex sponsalibus, in quibus fit quaedam, pactio coniugalis societatis, contrahitur aliquid affinitati simile, scilicet publicae honestatis iustitia.

a. 4 ad 3

Ad tertium dicendum quod omnia impedimenta quae faciunt sponsalia non esse sponsalia, non permittunt ex pactione nuptiarum affinitatem fieri. Unde sive habens defectum aetatis, sive habens votum solemne continentiae, aut aliquod huiusmodi impedimentum, sponsalia de facto contrahat, ex hoc non sequitur aliqua affinitas, quia sponsalia nulla sunt, nec aliquis affinitatis modus.

Si tamen aliquis minor frigidus vel maleficiatus habens impedimentum perpetuum, ante annos pubertatis post septennium contrahat sponsalia cum adulta, ex tali contractu contrahitur publicae honestatis iustitia: quia adhuc non erat in actu impediendi, cum in tali aetate puer frigidus et non frigidus, quantum ad actum illum, sint aequaliter impotentes.

a. 5 arg. 1

Ad quintum sic proceditur. Videtur etiam quod affinitas sit causa affinitatis. Quia Iulius Papa dicit: relictam consanguineorum uxoris suae nullus ducat uxorem, ut habetur XXXV, qu. 3, cap. Contradicimus. Et in sequenti capitulo dicitur quod duae consanguineorum uxores uni viro altera post alteram nubere prohibentur. Sed hoc non est nisi ratione affinitatis quae contrahitur ex coniunctione ad affinem. Ergo affinitas est causa affinitatis.

a. 5 arg. 2

Praeterea, carnalis commixtio coniungit sicut et carnalis propagatio: quia aequaliter computantur gradus affinitatis et consanguinitatis. Sed consanguinitas est causa affinitatis. Ergo et affinitas.

a. 5 arg. 3

Praeterea, quaecumque uni et eidem sunt eadem, sibi invicem sunt eadem. Sed uxor viri alicuius efficitur eiusdem attinentiae cum omnibus consanguineis viri. Ergo et omnes consanguinei viri sui efficiuntur unum cum omnibus qui attinent mulieri per affinitatem. Et sic affinitas est, causa affinitatis.

a. 5 s. c. 1

Sed contra: Si affinitas ex affinitate causatur, aliquis qui cognovisset duas mulieres, neutram earum posset ducere in uxorem: quia secundum hoc altera efficeretur alteri affinis. Sed hoc est falsum. Ergo affinitas non causat affinitatem.

a. 5 arg. 4

Praeterea, si affinitas ex affinitate nasceretur, aliquis contrahens cum uxore defuncti fieret affinis omnibus consanguineis prioris viri, ad quos mulier habet affinitatem. Sed hoc non potest esse: quia maxime fieret affinis viro defuncto. Ergo, etc.

a. 5 arg. 5

Praeterea, consanguinitas est fortius vinculum quam affinitas. Sed consanguinei uxoris non efficiuntur affines consanguineis viri. Ergo multo minus affines uxoris efficientur eis affines. Et sic idem quod prius.

a. 5 co.

Respondeo dicendum quod duplex est modus quo aliquid ex alio procedit: unus secundum quem aliquid procedit in similitudinem speciei, sicut ex homine generatur homo; alius secundum quem procedit dissimile in specie; et hic processus semper est in inferiorem speciem, ut patet in omnibus agentibus aequivoce. Primus autem modus processionis quotiescumque iteretur, semper manet eadem species: sicut, si ex homine generatur homo per actum generativae virtutis, ex hoc quoque generabitur homo, et sic deinceps. Secundus autem modus, sicut in principio facit aliam speciem, ita, quotiescumque iteretur, aliam speciem facit: ut, si ex puncto per motum procedit linea, non punctus quia punctus motus facit lineam, ex linea linealiter mota non procedit linea, sed superficies; et ex superficie corpus; et ulterius per talem modum processus aliquis non potest esse.

Invenimus autem in processu attinentiae duos modos quibus vinculum huiusmodi causatur. Unus per carnis propagationem: et hic semper facit eandem speciem attinentiae. Alius per matrimonialem coniunctionem: et hic facit aliam speciem in principio, sicut patet quod coniuncta matrimonialiter consanguineo, non fit consanguinea, sed affinis. Unde, si et ille modus procedendi iteratur, non erit affinitas, sed aliud attinentiae genus. Unde persona quae matrimonialiter affini coniungitur, non est affinis: sed est aliud genus affinitatis, quod dicatur secundum genus. Et rursus, si affini in secundo genere aliquis per matrimonium coniungatur, non erit affinis in secundo genere, sed in tertio. Ut hoc versu supra posito ostenditur: mutat nupta genus, sed generata gradus.

Et haec duo genera olim erant prohibita, propter publicae honestatis iustitiam magis quam propter affinitatem: quia deficiunt a vera affinitate, sicut illa attinentia quae ex sponsalibus contrahitur. Sed modo illa prohibitio cessavit. Et remanet sub prohibitione solum primum genus affinitatis, in quo est vera affinitas.
R: Q.. 55 a. 1[t:suppl q. 55 a. 1]

a. 5 ad 1

Ad primum ergo dicendum quod alicui viro consanguineus uxoris suae efficitur affinis in primo genere, et uxor eius in secundo. Unde, mortuo viro qui erat affinis, non poterat eam ducere in uxorem propter secundum affinitatis genus. Similiter autem, si aliquis viduam in uxorem ducat, consanguineus prioris viri, qui est affinis uxori in primo genere, efficitur affinis secundo viro in secundo genere: et uxor illius consanguinei, quae est affinis uxori viri huius in secundo genere, efficitur affinis viro secundo in tertio genere. Et quia tertium genus erat prohibitum, propter honestatem quandam magis quam propter affinitatem, ideo canon dicit: duas consanguineorum uxores uni viro alteram post alteram nubere publicae honestatis iustitiae contradicit. Sed talis prohibitio nunc cessavit.

a. 5 ad 2

Ad secundum dicendum quod, quamvis carnalis coniunctio coniungat, non tamen eodem genere coniunctionis.

a. 5 ad 3

Ad tertium dicendum quod uxor viri efficitur eiusdem attinentiae cum consanguineis viri quantum ad eundem gradum, sed non quantum ad idem attinentiae genus.

Sed quia ex rationibus quae in oppositum inducuntur videtur ostendi quod nullum vinculum ex affinitate causetur, ad alias rationes respondendum est: ne antiqua Ecclesiae prohibitio irrationabilis videatur.

a. 5 ad 4

Ad quartum dicendum, quod mulier non efficitur affinis in primo genere viro cui coniungitur carnaliter, ut ex praedictis patet. Unde consequenter alii mulieri a viro eodem cognitae non efficitur affinis in secundo genere. Unde nec ducenti in uxorem unam earum efficitur alia affinis in tertio genere affinitatis. Et ita duas mulieres cognitas ab eodem viro nec antiqua iura eidem successive copulari prohibebant:

a. 5 ad 5

Ad quintum dicendum quod, sicut vir non est affinis uxori suae in primo genere, ita nec efficitur affinis secundo viro eiusdem uxoris in secundo genere. Et sic ratio non procedit.

a. 5 ad 6

Ad sextum dicendum quod mediante una persona non coniungitur mihi alia nisi ex hoc quod ei adiungitur. Unde, mediante muliere quae mihi est affinis, nulla persona fit mihi attinens nisi quae illi mulieri adiungitur. Quod non potest esse nisi per carnis propagationem ex ipsa, vel propter coniunctionem matrimonialem ad eam. Et utroque modo aliqua attinentia mediante praedicta muliere, secundum antiqua iura, mihi proveniebat: quia filius eius etiam ex alio viro efficitur mihi affinis in eodem genere, sed in alio gradu, ut ex regula prius data patet; et iterum secundus vir eius efficitur mihi affinis in secundo genere. Sed alii consanguinei illius mulieris non adiunguntur ei: sed ipsa vel adiungitur eis, sicut patri et matri, inquantum procedit ab eis; vel principio eorundem, sicut fratribus. Unde frater affinis meae, vel pater, non efficitur mihi affinis in aliquo genere.

a. 6 arg. 1

Ad sextum sic proceditur. Videtur quod affinitas matrimonium non impediat. Nihil enim impedit matrimonium nisi quod est illi contrarium. Sed affinitas non contrariatur matrimonio: cum sit effectus eius. Ergo non impedit matrimonium.

a. 6 arg. 2

Praeterea, uxor per matrimonium efficitur res quaedam viri. Sed consanguinei defuncti viri succedunt in rebus eius. Ergo possunt succedere in uxore. Ad quam tamen manet affinitas, ut ostensum est. Ergo affinitas non impedit matrimonium.
R: Q.. 55 a. 5[t:suppl q. 55 a. 5]

a. 6 s. c. 1

Sed contra est quod dicitur Levit. 18: turpitudinem uxoris patris tui non revelabis. Sed illa est tantum affinis. Ergo affinitas impedit matrimonium.

a. 6 co.

Respondeo dicendum quod affinitas praecedens matrimonium impedit contrahendum et dirimit contractum: eadem ratione qua et consanguinitas. Sicut enim inest necessitas quaedam cohabitandi consanguineis ad invicem, ita et affinibus. Et sicut est quoddam amicitiae vinculum inter consanguineos, ita inter affines. Sed si affinitas matrimonio superveniat, non potest ipsum dirimere, ut supra dictum est.
R: Q.. 50[t:suppl q. 50]

a. 6 ad 1

Ad primum ergo dicendum quod affinitas non contrariatur matrimonio ex quo causatur: Sed contrariatur matrimonio quod cum affine contrahendum esset, inquantum impediret multiplicationem amicitiae et concupiscentiae repressionem, quae per matrimonium quaeruntur.

a. 6 ad 2

Ad secundum dicendum quod res possessae a viro non efficiuntur aliquid unum cum ipso viro, sicut uxor efficitur una caro cum ipso. Unde, sicut consanguinitas impedit coniunctionem ad virum, ita et ad uxorem viri.

a. 7 arg. 1

Ad septimum sic proceditur. Videtur quod affinitas habeat etiam per seipsam gradus. Cuiuslibet enim propinquitatis est accipere aliquos per se gradus. Sed affinitas propinquitas quaedam est. Ergo habet gradus per se, sine gradibus consanguinitatis, ex quibus causatur.

a. 7 arg. 2

Praeterea, in littera dicitur quod soboles secundae coniunctionis non potest transire ad consortium affinitatis prioris viri. Sed hoc non esset nisi filius affinis etiam esset affinis. Ergo affinitas habet per se gradus, sicut consanguinitas.

a. 7 s. c. 1

Sed contra, affinitas ex consanguinitate causatur. Ergo et omnes gradus affinitatis causantur ex gradibus consanguinitatis. Et sic non habet per se aliquos gradus.

a. 7 co.

Respondeo dicendum quod res non dividitur divisione per se nisi ratione illius quod competit sibi secundum genus suum: sicut animal per rationale et irrationale, non autem per album et nigrum. Carnis autem propagatio per se comparatur ad consanguinitatem, quia ex ea immediate consanguinitatis vinculum contrahitur: sed ad affinitatem non comparatur nisi mediante consanguinitate, quae est causa eius. Unde, cum gradus attinentiae per propagationem carnis distinguantur, distinctio graduum per se et immediate competit consanguinitati, sed affinitati mediante consanguinitate. Et ideo ad inveniendum gradus affinitatis est regula generalis quod, quoto gradu consanguinitatis attinet mihi vir, toto gradu affinitatis attinet mihi uxor.

a. 7 ad 1

Ad primum ergo dicendum quod gradus in propinquitate attinentiae non possunt accipi nisi secundum ascensum et descensum propagationis. Ad quam non comparatur affinitas nisi mediante consanguinitate. Et ideo non habet affinitas gradus per se, sed sumptos iuxta gradus consanguinitatis.

a. 7 ad 2

Ad secundum dicendum quod filius affinis meae ex alio matrimonio, non per se loquendo, sed quasi per accidens dicebatur antiquitus affinis. Unde prohibebatur a matrimonio magis propter publicae honestatis iustitiam quam propter affinitatem. Et propter hoc etiam illa prohibitio nunc est revocata.

a. 8 arg. 1

Ad octavum sic proceditur. Videtur quod gradus affinitatis non extendantur sicut gradus consanguinitatis. Quia vinculum affinitatis est minus forte quam consanguinitatis: cum affinitas ex consanguinitate causetur in diversitate speciei, sicut a causa aequivoca. Sed quanto fortius est vinculum, tanto diutius durat. Ergo vinculum affinitatis non durat usque ad tot gradus ad quot durat consanguinitas.

a. 8 arg. 2

Praeterea, ius humanum debet imitari ius divinum. Sed secundum ius divinum aliqui gradus consanguinitatis erant prohibiti in quibus gradibus affinitas matrimonium non impediebat: sicut patet de uxore fratris, quam aliquis poterat ducere in uxorem ipso defuncto, non tamen propriam sororem. Ergo et nunc non debet esse prohibitio aequalis de affinitate et consanguinitate.

a. 8 s. c. 1

Sed contra, ex hoc ipso est mihi aliqua affinis quod meo consanguineo est coniuncta. Ergo in quocumque gradu sit vir mihi consanguineus, in illo gradu erit uxor mihi affinis. Et sic gradus affinitatis computari debent in eodem numero sicut gradus consanguinitatis.

a. 8 co.

Respondeo dicendum quod ex quo gradus affinitatis sumuntur iuxta gradus consanguinitatis, oportet quod tot sint gradus affinitatis quot sunt gradus consanguinitatis. Sed tamen, quia affinitas est minus vinculum quam consanguinitas, facilius, et olim et nunc, dispensatio fit in remotis gradibus affinitatis quam in remotis gradibus consanguinitatis.

a. 8 ad 1

Ad primum ergo dicendum quod illa minoritas vinculi affinitatis respectu consanguinitatis, facit varietatem in genere attinentiae, non in gradibus. Et ideo illa ratio non est ad propositum.

a. 8 ad 2

Ad secundum dicendum quod frater non poterat accipere uxorem fratris sui defuncti nisi in casu, scilicet quando moriebatur sine prole, ut suscitaret semen fratri suo. Quod tunc requirebatur, quando per propagationem carnis cultus religionis multiplicabatur: quod nunc locum non habet. Et sic patet quod non ducebat eam uxorem quasi gerens propriam personam, sed quasi supplens defectum fratris sui.

a. 9 arg. 1

Ad nonum sic proceditur. Videtur quod coniugium quod inter affines vel consanguineos est contractum, non semper sit per divortium dirimendum. Quia quos Deus coniunxit, homo separare non debet. Cum ergo Deus facere intelligatur quod facit Ecclesia, quae quandoque tales ignoranter coniungit, videtur quod, si postmodum in notitiam veniant, non sunt separandi.

a. 9 arg. 2

Praeterea, favorabilius est vinculum matrimonii quam dominii. Sed homo per longi temporis praescriptionem acquirit dominium in re cuius non erat dominus. Ergo per diuturnitatem temporis matrimonium ratificatur, etiam si prius ratum non fuit.

a. 9 arg. 3

Praeterea, de similibus simile est iudicium. Sed si matrimonium esset dirimendum propter consanguinitatem, tunc, in casu illo quando duo fratres habent duas sorores in uxores, si unus separatur propter consanguinitatem, et alius pari ratione separari deberet. Quod non videtur. Ergo matrimonium non est separandum propter consanguinitatem vel affinitatem.

a. 9 s. c. 1

Sed contra, consanguinitas et affinitas impediunt contrahendum et dirimunt contractum. Ergo, si probatur affinitas vel consanguinitas, separandi sunt, etiam si de facto contraxerunt.

a. 9 co.

Respondeo dicendum quod, cum omnis concubitus praeter legitimum matrimonium sit peccatum mortale, quod Ecclesia omnibus modis impedire conatur, ad ipsam pertinet eos inter quos non potest esse verum matrimonium, separare: et praecipue consanguineos et affines, qui sine incestu contrahere non possunt carnaliter.

a. 9 ad 1

Ad primum ergo dicendum quod, quamvis Ecclesia dono et auctoritate divina fulciatur, tamen, inquantum est hominum congregatio, aliquid de defectu humano in actibus eius pervenit, quod non est divinum. Et ideo illa coniunctio quae fit in facie Ecclesiae impedimentis ignoratis, non habet inseparabilitatem ex auctoritate divina, sed est contra auctoritatem divinam errore hominum inducta: qui excusat a peccato, cum sit error facti, quandiu manet. Et propter hoc, quando impedimentum ad notitiam pervenit Ecclesiae, debet praedictam coniunctionem separare.

a. 9 ad 2

Ad secundum dicendum quod illa quae sine peccato esse non possunt, nulla praescriptione firmantur: quia, ut Innocentius dicit, diuturnitas temporis non minuit peccatum, sed auget. Nec ad hoc facit aliquod favor matrimonii, quod inter illegitimas personas esse non poterat.

a. 9 ad 3

Ad tertium dicendum quod res inter alios acta, aliis non praeiudicat in foro contentioso. Unde, quamvis unus frater repellatur a matrimonio unius sororum ex causa consanguinitatis, non propter hoc separat Ecclesia aliud matrimonium, quod non accusatur. Sed in foro conscientiae non oportet quod semper obligetur ob hoc alius frater ad dimittendum uxorem suam: quia frequenter tales accusationes ex malevolentia procedunt, et per falsos testes probantur; unde non oportet quod conscientiam suam informet ex his quae circa aliud matrimonium sunt facta. Sed distinguendum videtur in hoc. Quia aut habet certam scientiam de impedimento matrimonii, aut opinionem, aut neutrum. Si primo modo, nec exigere nec reddere debitum debet; si secundo, debet reddere, sed non exigere; si tertio, potest reddere et exigere.

a. 10 arg. 1

Ad decimum sic proceditur. Videtur quod ad separationem matrimonii quod est inter affines et consanguineos contractum, non sit procedendum per viam accusationis. Quia accusationem praecedit inscriptio, qua aliquis se ad talionem obligat si in probatione defecerit. Sed haec non requiruntur quando de matrimonii separatione agitur. Ergo ibi locum non habet accusatio.

a. 10 arg. 2

Praeterea, in causa matrimonii audiuntur solum propinqui, ut in littera dicitur. Sed in accusationibus audiuntur etiam extranei. Ergo in causa separationis matrimonii non agitur per viam accusationis.

a. 10 arg. 3

Praeterea, si matrimonium accusari deberet, tunc praecipue hoc esset faciendum quando minus difficile est quod separetur. Sed hoc est quando sunt sponsalia tantum contracta. Non autem tunc accusatur matrimonium. Ergo nunquam de cetero debet fieri accusatio.

a. 10 arg. 4

Praeterea, ad accusandum non praecluditur via alicui per hoc quod non statim accusat. Sed hoc fit in matrimonio: quia, si primo tacuit quando matrimonium contrahebatur, non potest postea matrimonium accusare, quasi suspectus. Ergo, etc.

a. 10 s. c. 1

Sed contra, omne illicitum potest accusari. Sed matrimonium affinium vel consanguineorum est illicitum. Ergo de eo potest esse accusatio.

a. 10 co.

Respondeo dicendum quod accusatio ad hoc est instituta ne aliquis sustineatur quasi innocens qui culpam habet. Sicut autem ex ignorantia facti contingit quod aliquis homo reputatur innocens qui in culpa est, ita ex ignorantia alicuius circumstantiae contingit quod aliquod factum reputatur licitum quod est illicitum. Et ideo, sicut homo accusatur quandoque, ita et factum ipsum accusari potest. Et sic matrimonium accusatur quando, propter ignorantiam impedimenti, aestimatur legitimum quod est illegitimum.

a. 10 ad 1

Ad primum ergo dicendum quod obligatio ad poenam talionis habet locum quando accusatur persona, de crimine, quia tunc agitur ad punitionem eius. Sed quando accusatur factum, tunc non agitur ad poenam facientis, sed ad impediendum quod est illicitum. Et ideo in matrimonio accusator non se obligat ad aliquam poenam: sed talis accusatio potest et verbis et scripto fieri, ita quod exprimatur et persona accusans matrimonium quod accusatur, et impedimentum propter quod accusatur.

a. 10 ad 2

Ad secundum dicendum quod extranei non possunt scire consanguinitatem nisi per consanguineos, de quibus probabilius est quod sciant. Unde, quando ipsi tacent, suspicio habetur, contra extraneum quod ex malevolentia procedat, nisi per consanguineos probare voluerit. Unde repellitur ab accusatione quando sunt consanguinei qui tacent, et per quod probare non potest. Sed consanguinei, quantumcumque sint propinqui, non repelluntur ab accusatione quando accusatur matrimonium propter aliquod impedimentum perpetuum, quod impedit contrahendum et dirimit contractum. Sed quando accusatur ex hoc quod dicitur non fuisse contractum, tunc parentes tanquam suspecti sunt repellendi: nisi ex parte illius qui est inferior dignitate et divitiis, de quibus probabiliter aestimari potest quod: libenter vellent quod matrimonium staret.

a. 10 ad 3

Ad tertium dicendum quod, quando matrimonium nondum est contractum, sed sponsalia tantum, non potest accusari, quia non accusatur quod non est. Sed potest denuntiari impedimentum, ne matrimonium contrahatur.

a. 10 ad 4

Ad quartum dicendum quod ille qui tacuit primo, quandoque auditur postea, si velit matrimonium accusare, quandoque repellitur. Quod patet ex Decretali, quae sic dicit: si post contractum matrimonium: aliquis appareat accusator, cum non prodierit in publicum quando, secundum consuetudinem, in ecclesiis edebatur: utrum vox suae accusationis debeat admitti; merito quaeri potest. Super quo respondemus quod, si tempore denuntiationis praemissae is qui iam coniunctos impetit, extra dioecesim existebat, vel alias denunciatio non potuit ad eius devenire notitiam, ut puta si nimiae infirmitatis fervore laborans sanae mentis patiebatur exilium, vel in annis erat tam teneris constitutus quod ad comprehensionem talium eius aetas sufficere non valebat, seu alia causa legitima fuerit impeditus, eius accusatio debet audiri. Alioquin, tanquam suspectus est procul dubio repellendus: nisi firmaverit iuramento quod post didicerit ea quae obiecerit, et ad hoc ex malitia non procedat.

a. 11 arg. 1

Ad undecimum sic proceditur. Videtur quod in tali causa non sit procedendum per testes, sicut in aliis causis. Quia in aliis causis adducuntur ad testificandum quicumque sunt omni exceptione maiores. Sed hic non admittuntur extranei, quamvis sint omni exceptione maiores. Ergo, etc.

a. 11 arg. 2

Praeterea, testes suspecti de privato odio vel amore a testimonio repelluntur. Sed maxime possunt propinqui esse suspecti de amore respectu unius partis et odio ad partem alteram. Ergo non est audiendum eorum testimonium.

a. 11 arg. 3

Praeterea, matrimonium est favorabilius quam aliae causae, in quibus de rebus pure corporalibus agitur. Sed in illis non potest idem esse testis et accusator. Ergo nec in matrimonio. Et ita videtur quod non convenienter in causa ista per testes procedatur.

a. 11 s. c. 1

Sed contra, testes inducuntur in causis ut super his de quibus dubitatur fiat iudici fides. Sed ita facienda est iudici fides in causa ista sicut in aliis causis: quia non debet praecipitare sententiam de eo quod non constat. Ergo procedendum est hic ex testibus, sicut in aliis causis.

a. 11 co.

Respondeo dicendum quod in hac causa oportet quod per testes veritas patefiat, sicut et in aliis. Tamen, ut iuristae dicunt, in hac causa multa specialia inveniuntur: scilicet, quod idem potest esse accusator et testis; et quod non iuratur de calumnia, cum sit causa quasi spiritualis; et quod consanguinei admittuntur ad testificandum, et quod non observatur omnino ordo iudiciarius quia, tali denuntiatione facta, contumax potest excommunicari lite non contestata; et valet hic testimonium de auditu; et post publicationem testium testes possunt induci. Et hoc totum est ut peccatum impediatur, quod in tali coniunctione esse potest.

a. 11 ad 1

Et per hoc patet solutio ad obiecta.
