Whether the Mother of God took a vow of virginity?

❌ Objection 1 : It would seem that the Mother of God did not take a vow of virginity. For it is written (Dt. 7:14): "No one shall be barren among you of either sex." But sterility is a consequence of virginity. Therefore the keeping of virginity was contrary to the commandment of the Old Law. But before Christ was born the old law was still in force. Therefore at that time the Blessed Virgin could not lawfully take a vow of virginity.

❌ Objection 2 : Further, the Apostle says (1 Cor. 7:25): "Concerning virgins I have no commandment of the Lord; but I give counsel." But the perfection of the counsels was to take its beginning from Christ, who is the "end of the Law," as the Apostle says (Rm. 10:4). It was not therefore becoming that the Virgin should take a vow of virginity.

❌ Objection 3 : Further, the gloss of Jerome says on 1 Tim. 5:12, that "for those who are vowed to virginity, it is reprehensible not only to marry, but also to desire to be married." But the Mother of Christ committed no sin for which she could be reprehended, as stated above (Question [27], Article [4]). Since therefore she was "espoused," as related by Lk. 1:27 it seems that she did not take a vow of virginity.
