Mary said to the angel, "How can this be, seeing I am a virgin?"
The conjecture which some have drawn from these words, that she had formed a vow of perpetual virginity, is unfounded and altogether absurd. She would, in that case, have committed treachery by allowing herself to be united to a husband, and would have poured contempt on the holy covenant of marriage; which could not have been done without mockery of God. Although the Papists have exercised barbarous tyranny on this subject, yet they have never proceeded so far as to allow the wife to form a vow of continence at her own pleasure. Besides, it is an idle and unfounded supposition that a monastic life existed among the Jews.
