Whether the consent that makes a marriage is a consent to carnal intercourse?

Objections

Objection 1 : It would seem that the consent which makes a marriage is a consent to carnal intercourse. For Jerome [*The words quoted are found implicitly in St. Augustine (De Bono Viduit ix)] says that "for those who have vowed virginity it is wicked, not only to marry, but even to wish to marry." But it would not be wicked unless it were contrary to virginity, and marriage is not contrary to virginity except by reason of carnal intercourse. Therefore the will's consent in marriage is a consent to carnal intercourse.
Objection 2 : Further, whatever there is in marriage between husband and wife is lawful between brother and sister except carnal intercourse. But there cannot lawfully be a consent to marriage between them. Therefore the marriage consent is a consent to carnal intercourse.
Objection 3 : Further, if the woman say to the man: "I consent to take thee provided however that you know me not," it is not a marriage consent, because it contains something against the essence of that consent. Yet this would not be the case unless the marriage consent were a consent to carnal intercourse. Therefore, etc.
Objection 4 : Further, in everything the beginning corresponds to the consummation. Now marriage is consummated by carnal intercourse. Therefore, since it begins by the consent, it would seem that the consent is to carnal intercourse.
