Thomas Aquinas - Summa Theologica, Part III (Tertia Pars)

FOURTH ARTICLE [III, Q. 28, Art. 4]

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 (Deut. 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.

Obj. 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 (Rom. 10:4). It was not therefore becoming that the Virgin should take a vow of virginity.

Obj. 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 (Q. 27, A. 4). Since therefore she was "espoused," as related by Luke 1:27 it seems that she did not take a vow of virginity.

On the contrary, Augustine says (De Sanct. Virg. iv): "Mary answered the announcing angel: 'How shall this be done, because I know not man?' She would not have said this unless she had already vowed her virginity to God."

I answer that, As we have stated in the Second Part (II-II, Q. 88, A. 6), works of perfection are more praiseworthy when performed in fulfilment of a vow. Now it is clear that for reasons already given (AA. 1, 2, 3) virginity had a special place in the Mother of God. It was therefore fitting that her virginity should be consecrated to God by vow. Nevertheless because, while the Law was in force both men and women were bound to attend to the duty of begetting, since the worship of God was spread according to carnal origin, until Christ was born of that people; the Mother of God is not believed to have taken an absolute vow of virginity, before being espoused to Joseph, although she desired to do so, yet yielding her own will to God's judgment. Afterwards, however, having taken a husband, according as the custom of the time required, together with him she took a vow of virginity.

Reply Obj. 1: Because it seemed to be forbidden by the law not to take the necessary steps for leaving a posterity on earth, therefore the Mother of God did not vow virginity absolutely, but under the condition that it were pleasing to God. When, however, she knew that it was acceptable to God, she made the vow absolute, before the angel's Annunciation.

Reply Obj. 2: Just as the fulness of grace was in Christ perfectly, yet some beginning of the fulness preceded in His Mother; so also the observance of the counsels, which is an effect of God's grace, began its perfection in Christ, but was begun after a fashion in His Virgin Mother.

Reply Obj. 3: These words of the Apostle are to be understood of those who vow chastity absolutely. Christ's Mother did not do this until she was espoused to Joseph. After her espousals, however, by their common consent she took a vow of virginity together with her spouse.

We now consider the espousals of God's Mother: concerning which two points arise for inquiry:

(1) Whether Christ should have been born of an espoused virgin?

(2) Whether there was true marriage between our Lord's Mother and Joseph? _______________________

FIRST ARTICLE [III, Q. 29, Art. 1]

Whether Christ Should Have Been Born of an Espoused Virgin?

Objection 1: It would seem that Christ should not have been born of an espoused virgin. For espousals are ordered to carnal intercourse. But our Lord's Mother never wished to have carnal intercourse with her husband; because this would be derogatory to the virginity of her mind. Therefore she should not have been espoused.

Obj. 2: Further, that Christ was born of a virgin was miraculous, whence Augustine says (Ep. ad Volus. cxxxvii): "This same power of God brought forth the infant's limbs out of the virginal womb of His inviolate Mother, by which in the vigor of manhood He passed through the closed doors. If we are told why this happened, it will cease to be wonderful; if another instance be alleged, it will no longer be unique." But miracles that are wrought in confirmation of the Faith should be manifest. Since, therefore, by her Espousals this miracle would be less evident, it seems that it was unfitting that Christ should be born of an espoused virgin.

Obj. 3: Further, the martyr Ignatius, as Jerome says on Matt. 1:18, gives as a reason of the espousals of the Mother of God, "that the manner of His Birth might be hidden from the devil, who would think Him to be begotten not of a virgin but of a wife." But this seems to be no reason at all. First, because by his natural cunning he knows whatever takes place in bodies. Secondly, because later on the demons, through many evident signs, knew Christ after a fashion: whence it is written (Mk. 1:23, 24): "A man with an unclean spirit . . . cried out, saying: What have we to do with Thee, Jesus of Nazareth? Art Thou come to destroy us? I know . . . Thou art the Holy one of God." Therefore it does not seem fitting that the Mother of God should have been espoused.

Obj. 4: Further, Jerome gives as another reason, "lest the Mother of God should be stoned by the Jews as an adulteress." But this reason seems to have no weight, for if she were not espoused, she could not be condemned for adultery. Therefore it does not seem reasonable that Christ should be born of an espoused virgin.

On the contrary, It is written (Matt. 1:18): "When as His Mother Mary was espoused to Joseph": and (Luke 1:26, 27): "The angel Gabriel was sent . . . to a virgin espoused to a man whose name was Joseph."

I answer that, It was fitting that Christ should be born of an espoused virgin; first, for His own sake; secondly, for His Mother's sake; thirdly, for our sake. For the sake of Christ Himself, for four reasons. First, lest He should be rejected by unbelievers as illegitimate: wherefore Ambrose says on Luke 1:26, 27: "How could we blame Herod or the Jews if they seem to persecute one who was born of adultery?"

Secondly, in order that in the customary way His genealogy might be traced through the male line. Thus Ambrose says on Luke 3:23: "He Who came into the world, according to the custom of the world had to be enrolled. Now for this purpose, it is the men that are required, because they represent the family in the senate and other courts. The custom of the Scriptures, too, shows that the ancestry of the men is always traced out."

Thirdly, for the safety of the new-born Child: lest the devil should plot serious hurt against Him. Hence Ignatius says that she was espoused "that the manner of His Birth might be hidden from the devil."

Fourthly, that He might be fostered by Joseph: who is therefore called His "father," as bread-winner.

It was also fitting for the sake of the Virgin. First, because thus she was rendered exempt from punishment; that is, "lest she should be stoned by the Jews as an adulteress," as Jerome says.

Secondly, that thus she might be safeguarded from ill fame. Whence Ambrose says on Luke 1:26, 27: "She was espoused lest she be wounded by the ill-fame of violated virginity, in whom the pregnant womb would betoken corruption."

Thirdly, that, as Jerome says, Joseph might administer to her wants.

This was fitting, again, for our sake. First, because Joseph is thus a witness to Christ's being born of a virgin. Wherefore Ambrose says: "Her husband is the more trustworthy witness of her purity, in that he would deplore the dishonor, and avenge the disgrace, were it not that he acknowledged the mystery."
