[¶0] Whether it is allowable for a menstruous wife to ask for the marriage debt? [*This and the Fourth Article are omitted in the Leonine edition.]

[¶1] Objection 1: It would seem lawful for a menstruous wife to ask for the marriage debt. For in the Law a man who had an issue of seed was unclean, even as a menstruous woman. Yet a man who has an issue of seed may ask for the debt. Therefore a menstruous wife may also.

[¶2] Objection 2: Further, leprosy is a worse complaint than suffering from monthly periods, and would seem to cause a greater corruption in the offspring. Yet a leper can ask for the debt. Therefore, etc.

[¶3] Objection 3: Further, if a menstruous wife is not allowed to ask for the debt, this can only be because it is feared this may be detrimental to the offspring. Yet if the wife be unfruitful there is no such fear. Therefore, seemingly, at least an unfruitful wife may ask for the debt during her menses.

[¶4] On the contrary, "Thou shalt not approach to a woman having her flowers" (Lev. 18:19) where Augustine observes: "Although he has already sufficiently forbidden this he repeats the prohibition here lest he seem to have spoken figuratively."

[¶5] Further, "All our justices" are become "as the rag of a menstruous woman" (Is. 64:6) where Jerome observes: "Men ought then to keep away from their wives because thus is a deformed blind lame leprous offspring conceived: so that those parents who are not ashamed to come together in sexual intercourse have their sin made obvious to all": and thus the same conclusion follows.

[¶6] I answer that, It was forbidden in the Law to approach to a menstruous woman, for two reasons both on account of her uncleanness, and on account of the harm that frequently resulted to the offspring from such intercourse. With regard to the first reason, it was a ceremonial precept, but with regard to the second it was a moral precept. For since marriage is chiefly directed to the good of the offspring, all use of marriage which is intended for the good of the offspring is in order. Consequently this precept is binding even in the New Law on account of the second reason, although not on account of the first. Now, the menstrual issue may be natural or unnatural. The natural issue is that to which women are subject at stated periods when they are in good health; and it is unnatural when they suffer from an issue of blood through some disorder resulting from sickness. Accordingly if the menstrual flow be unnatural it is not forbidden in the New Law to approach to a menstruous woman both on account of her infirmity since a woman in that state cannot conceive, and because an issue of this kind is lasting and continuous, so that the husband would have to abstain for always. When however the woman is subject to a natural issue of the menstruum, she can conceive; moreover, the said issue lasts only a short time, wherefore it is forbidden to approach to her. In like manner a woman is forbidden to ask for the debt during the period of that issue.

[¶7] Reply to Objection 1: The issue of seed in a man is the result of infirmity, nor is the seed in this case apt for generation. Moreover a complaint of this kind is continual or lasting like leprosy: wherefore the comparison falls.

[¶8] This suffices for the Reply to the Second Objection.

[¶9] Reply to Objection 3: As long as a woman is subject to the menses it cannot be certain that she is sterile. For some are sterile in youth, and in course of time become fruitful, and "vice versa," as the Philosopher observes (De Gener. Anim. xvi).

### Supp. · Q. 64, Art. 4: Whether a menstruous woman should or may lawfully pay the marriage debt  to her husband if he ask for it?

[¶11] Whether a menstruous woman should or may lawfully pay the marriage debt to her husband if he ask for it? [*This and the previous article are omitted in the Leonine edition.]

[¶12] Objection 1: It would seem that a menstruous wife may not pay the marriage debt to her husband at his asking. For it is written (Lev. 20:18) that if any man approach to a menstruous woman both shall be put to death. Therefore it would seem that both he who asks and she who grants are guilty of mortal sin.

[¶13] Objection 2: Further, "Not only they that do them but they also that consent to them are worthy of death" (Rom. 1:32). Now he who knowingly asks for the debt from a menstruous woman sins mortally. Therefore she also sins mortally by consenting to pay the debt.

[¶14] Objection 3: Further, a madman must not be given back his sword lest he kill himself or another. Therefore in like manner neither should a wife give her body to her husband during her menses, lest he be guilty of spiritual murder.

[¶15] On the contrary, "The wife hath not power of her own body, but the husband" (1 Cor. 7:4). Therefore at his asking his wife must pay the debt even during her menses.

[¶16] Further, the menstruous wife should not be an occasion of sin to her husband. But she would give her husband an occasion of sin, if she paid him not the debt at his asking; since he might commit fornication. Therefore, etc.

[¶17] I answer that, In this regard some have asserted that a menstruous woman may not pay the debt even as she may not ask for it. For just as she would not be bound to pay it if she had some personal ailment so as to make it dangerous for herself, so is she not bound to pay for fear of danger to the offspring. But this opinion would seem to derogate from marriage, by which the husband is given entire power of his wife's body with regard to the marriage act. Nor is there any parallel between bodily affliction of the offspring and the danger to her own body: since, if the wife be ailing, it is quite certain that she would be endangered by the carnal act, whereas this is by no means so certain with regard to the offspring which perhaps would not be forthcoming.

[¶18] Wherefore others say that a menstruous woman is never allowed to ask for the debt; and that if her husband ask, he does so either knowingly or in ignorance. If knowingly, she ought to dissuade him by her prayers and admonitions; yet not so insistently as possibly to afford him an occasion of falling into other, and those sinful, practices, if he be deemed that way inclined. If however, he ask in ignorance, the wife may put forward some motive, or allege sickness as a reason for not paying the debt, unless there be fear of danger to her husband. If, however, the husband ultimately persists in his request, she must yield to his demand. But it would not be safe for her to make known [*"Indicare," as in the commentary on the Sentences; the Leonine edition reads "judicare."] her disaffection, lest this make her husband entertain a repulsion towards her, unless his prudence may be taken for granted.

[¶19] Reply to Objection 1: This refers to the case when both willingly consent, but not when the woman pays the debt by force as it were.

[¶20] Reply to Objection 2: Since there is no consent without the concurrence of the will, the woman is not deemed to consent in her husband's sin unless she pay the debt willingly. For when she is unwilling she is passive rather than consenting.

[¶21] Reply to Objection 3: A madman should be given back his sword if a greater danger were feared from its not being returned to him: and thus it is in the case in point.
