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

Secondly, because thereby the very words of the Virgin are rendered more credible by which she asserted her virginity. Thus Ambrose says: "Belief in Mary's words is strengthened, the motive for a lie is removed. If she had not been espoused when pregnant, she would seem to have wished to hide her sin by a lie: being espoused, she had no motive for lying, since a woman's pregnancy is the reward of marriage and gives grace to the nuptial bond." These two reasons add strength to our faith.

Thirdly, that all excuse be removed from those virgins who, through want of caution, fall into dishonor. Hence Ambrose says: "It was not becoming that virgins should expose themselves to evil report, and cover themselves with the excuse that the Mother of the Lord had also been oppressed by ill-fame."

Fourthly, because by this the universal Church is typified, which is a virgin and yet is espoused to one Man, Christ, as Augustine says (De Sanct. Virg. xii).

A fifth reason may be added: since the Mother of the Lord being both espoused and a virgin, both virginity and wedlock are honored in her person, in contradiction to those heretics who disparaged one or the other.

Reply Obj. 1: We must believe that the Blessed Virgin, Mother of God, desired, from an intimate inspiration of the Holy Ghost, to be espoused, being confident that by the help of God she would never come to have carnal intercourse: yet she left this to God's discretion. Wherefore she suffered nothing in detriment to her virginity.

Reply Obj. 2: As Ambrose says on Luke 1:26: "Our Lord preferred that men should doubt of His origin rather than of His Mother's purity. For he knew the delicacy of virgin modesty, and how easily the fair name of chastity is disparaged: nor did He choose that our faith in His Birth should be strengthened in detriment to His Mother." We must observe, however, that some miracles wrought by God are the direct object of faith; such are the miracles of the virginal Birth, the Resurrection of our Lord, and the Sacrament of the Altar. Wherefore our Lord wished these to be more hidden, that belief in them might have greater merit. Whereas other miracles are for the strengthening of faith: and these it behooves to be manifest.

Reply Obj. 3: As Augustine says (De Trin. iii), the devil can do many things by his natural power which he is hindered by the Divine power from doing. Thus it may be that by his natural power the devil could know that the Mother of God knew not man, but was a virgin; yet was prevented by God from knowing the manner of the Divine Birth. That afterwards the devil after a fashion knew that He was the Son of God, makes no difficulty: because then the time had already come for Christ to make known His power against the devil, and to suffer persecution aroused by him. But during His infancy it behooved the malice of the devil to be withheld, lest he should persecute Him too severely: for Christ did not wish to suffer such things then, nor to make His power known, but to show Himself to be in all things like other infants. Hence Pope Leo (Serm. in Epiph. iv) says that "the Magi found the Child Jesus small in body, dependent on others, unable to speak, and in no way differing from the generality of human infants." Ambrose, however, expounding Luke 1:26, seems to understand this of the devil's members. For, after giving the above reason—namely, that the prince of the world might be deceived—he continues thus: "Yet still more did He deceive the princes of the world, since the evil disposition of the demons easily discovers even hidden things: but those who spend their lives in worldly vanities can have no acquaintance of Divine things."

Reply Obj. 4: The sentence of adulteresses according to the Law was that they should be stoned, not only if they were already espoused or married, but also if their maidenhood were still under the protection of the paternal roof, until the day when they enter the married state. Thus it is written (Deut. 22:20, 21): "If . . . virginity be not found in the damsel . . . the men of the city shall stone her to death, and she shall die; because she hath done a wicked thing in Israel, to play the whore in her father's house."

It may also be said, according to some writers, that the Blessed Virgin was of the family or kindred of Aaron, so that she was related to Elizabeth, as we are told (Luke 1:36). Now a virgin of the priestly tribe was condemned to death for whoredom; for we read (Lev. 21:9): "If the daughter of a priest be taken in whoredom, and dishonor the name of her father, she shall be burnt with fire."

Lastly, some understand the passage of Jerome to refer to the throwing of stones by ill-fame. _______________________

SECOND ARTICLE [III, Q. 29, Art. 2]

Whether there was a true marriage between Mary and Joseph?

Objection 1: It would seem that there was no true marriage between Mary and Joseph. For Jerome says against Helvidius that Joseph "was Mary's guardian rather than her husband." But if this was a true marriage, Joseph was truly her husband. Therefore there was no true marriage between Mary and Joseph.

Obj. 2: Further, on Matt. 1:16: "Jacob begot Joseph the husband of Mary," Jerome says: "When thou readest 'husband' suspect not a marriage; but remember that Scripture is wont to speak of those who are betrothed as husband and wife." But a true marriage is not effected by the betrothal, but by the wedding. Therefore, there was no true marriage between the Blessed Virgin and Joseph.

Obj. 3: Further, it is written (Matt. 1:19): "Joseph, her husband, being a just man, and not willing to take her away [*Douay: 'publicly to expose her'], i.e. to take her to his home in order to cohabit with her, was minded to put her away privately, i.e. to postpone the wedding," as Remigius [*Cf. Catena Aurea in Matth.] expounds. Therefore, it seems that, as the wedding was not yet solemnized, there was no true marriage: especially since, after the marriage contract, no one can lawfully put his wife away.

On the contrary, Augustine says (De Consensu Evang. ii): "It cannot be allowed that the evangelist thought that Joseph ought to sever his union with Mary" (since he said that Joseph was Mary's husband) "on the ground that in giving birth to Christ, she had not conceived of him, but remained a virgin. For by this example the faithful are taught that if after marriage they remain continent by mutual consent, their union is still and is rightly called marriage, even without intercourse of the sexes."

I answer that, Marriage or wedlock is said to be true by reason of its attaining its perfection. Now perfection of anything is twofold; first, and second. The first perfection of a thing consists in its very form, from which it receives its species; while the second perfection of a thing consists in its operation, by which in some way a thing attains its end. Now the form of matrimony consists in a certain inseparable union of souls, by which husband and wife are pledged by a bond of mutual affection that cannot be sundered. And the end of matrimony is the begetting and upbringing of children: the first of which is attained by conjugal intercourse; the second by the other duties of husband and wife, by which they help one another in rearing their offspring.

Thus we may say, as to the first perfection, that the marriage of the Virgin Mother of God and Joseph was absolutely true: because both consented to the nuptial bond, but not expressly to the bond of the flesh, save on the condition that it was pleasing to God. For this reason the angel calls Mary the wife of Joseph, saying to him (Matt. 1:20): "Fear not to take unto thee Mary thy wife": on which words Augustine says (De Nup. et Concup. i): "She is called his wife from the first promise of her espousals, whom he had not known nor ever was to know by carnal intercourse."

But as to the second perfection which is attained by the marriage act, if this be referred to carnal intercourse, by which children are begotten; thus this marriage was not consummated. Wherefore Ambrose says on Luke 1:26, 27: "Be not surprised that Scripture calls Mary a wife. The fact of her marriage is declared, not to insinuate the loss of virginity, but to witness to the reality of the union." Nevertheless, this marriage had the second perfection, as to upbringing of the child. Thus Augustine says (De Nup. et Concup. i): "All the nuptial blessings are fulfilled in the marriage of Christ's parents, offspring, faith and sacrament. The offspring we know to have been the Lord Jesus; faith, for there was no adultery: sacrament, since there was no divorce. Carnal intercourse alone there was none."
