Reply to Objection 3: If the woman admit her betrothed, thinking that he wishes to consummate the marriage, she is excused from the sin, unless there be clear signs of fraud; for instance if they differ considerably in birth or fortune, or some other evident sign appear. Nevertheless the affianced husband is guilty of fornication, and should be punished for this fraud he has committed.
Reply to Objection 4: In a case of this kind the affianced husband, before his marriage with the other woman, is bound to marry the one to whom he was betrothed, if she be his equal or superior in rank. But if he has married another woman, he is no longer able to fulfill his obligation, wherefore it suffices if he provide for her marriage. Nor is he bound even to do this, according to some, if her affianced husband is of much higher rank than she, or if there be some evident sign of fraud, because it may be presumed that in all probability she was not deceived but pretended to be.
