The key to understanding all these graces is Mary’s role as the New Eve, which the Fathers proclaimed so forcefully. Because she is the New Eve, she, like the New Adam, is born immaculate, just as the First Adam and Eve were created immaculate. Because she is New Eve, she is mother of the new mankind (Christians), just as the first Eve was the mother of first mankind (the children of Adam). And, because she is the New Eve, she shares the fate of the New Adam. The First Adam and Eve died and went to dust; the New Adam and Eve were physically raised to heaven.
Of particular interest in the following quotations from the Fathers are those that speak of Mary’s immaculate nature. We all one day will be rendered immaculate (sinless), but Mary, as the prototypical Christian, received this grace early. God granted it to make her a fitting mother for his Son.
Before the terms "original sin" and "immaculate conception" were even coined, early passages imply the doctrines. Many works mention that Mary gave birth to Jesus without pain. Pain in childbearing is part of the penalty of original sin (Gen. 3:16). Thus, Mary could not have been under that penalty. By God’s grace, she was immaculate in anticipation of her Son’s redeeming death on the cross. The Church therefore describes Mary as "the most excellent fruit of redemption" (CCC 508).
The Ascension of Isaiah
"[T]he report concerning the child was noised abroad in Bethlehem. Some said, ‘The Virgin Mary has given birth before she was married two months.’ And many said, ‘She has not given birth; the midwife has not gone up to her, and we heard no cries of pain’" (Ascension of Isaiah 11 [A.D. 70]).
The Odes of Solomon
"So the Virgin became a mother with great mercies. And she labored and bore the Son, but without pain, because it did not occur without purpose. And she did not seek a midwife, because he caused her to give life. She bore as a strong man, with will. . . . " (Odes of Solomon 19 [A.D. 80]).
"[Jesus] became man by the Virgin so that the course which was taken by disobedience in the beginning through the agency of the serpent might be also the very course by which it would be put down. Eve, a virgin and undefiled, conceived the word of the serpent and bore disobedience and death. But the Virgin Mary received faith and joy when the angel Gabriel announced to her the glad tidings that the Spirit of the Lord would come upon her and the power of the Most High would overshadow her, for which reason the Holy One being born of her is the Son of God. And she replied, ‘Be it done unto me according to your word’ [Luke 1:38]" (Dialogue with Trypho the Jew 100 [A.D. 155]).
"Consequently, then, Mary the Virgin is found to be obedient, saying, ‘Behold, O Lord, your handmaid; be it done to me according to your word.’ Eve, however, was disobedient, and, when yet a virgin, she did not obey. Just as she, who was then still a virgin although she had Adam for a husband—for in paradise they were both naked but were not ashamed; for, having been created only a short time, they had no understanding of the procreation of children, and it was necessary that they first come to maturity before beginning to multiply—having become disobedient, was made the cause of death for herself and for the whole human race; so also Mary, betrothed to a man but nevertheless still a virgin, being obedient, was made the cause of salvation for herself and for the whole human race. . . . Thus, the knot of Eve’s disobedience was loosed by the obedience of Mary. What the virgin Eve had bound in unbelief, the Virgin Mary loosed through faith" (Against Heresies 3:22:24 [A.D. 189]).
"And again, lest I depart from my argumentation on the name of Adam: Why is Christ called Adam by the apostle, if as man he was not of that earthly origin? But even reason defends this conclusion, that God recovered his image and likeness by a procedure similar to that in which he had been robbed of it by the devil. It was while Eve was still a virgin that the word of the devil crept in to erect an edifice of death. Likewise through a Virgin the Word of God was introduced to set up a structure of life. Thus what had been laid waste in ruin by this sex was by the same sex reestablished in salvation. Eve had believed the serpent; Mary believed Gabriel. That which the one destroyed by believing, the other, by believing, set straight" (The Flesh of Christ 17:4 [A.D. 210].
"If therefore it might come to pass by the power of your grace, it has appeared right to us your servants that, as you, having overcome death, do reign in glory, so you should raise up the body of your Mother and take her with you, rejoicing, into heaven. Then said the Savior [Jesus]: ‘Be it done according to your will" (The Passing of the Virgin 16:2–17 [A.D. 300]).
"You alone and your Mother are more beautiful than any others, for there is no blemish in you nor any stains upon your Mother. Who of my children can compare in beauty to these?" (Nisibene Hymns 27:8 [A.D. 361]).
"Mary’s life should be for you a pictorial image of virginity. Her life is like a mirror reflecting the face of chastity and the form of virtue. Therein you may find a model for your own life . . . showing what to improve, what to imitate, what to hold fast to" (The Virgins 2:2:6 [A.D. 377]).
"Come, then, and search out your sheep, not through your servants or hired men, but do it yourself. Lift me up bodily and in the flesh, which is fallen in Adam. Lift me up not from Sarah but from Mary, a virgin not only undefiled, but a virgin whom grace had made inviolate, free of every stain of sin" (Commentary on Psalm 118. 22–30 [A.D. 387]).
"That one woman is both mother and virgin, not in spirit only but even in body. In spirit she is mother, not of our head, who is our Savior himself—of whom all, even she herself, are rightly called children of the bridegroom—but plainly she is the mother of us who are his members, because by love she has cooperated so that the faithful, who are the members of that head, might be born in the Church. In body, indeed, she is the mother of that very head" (Holy Virginity 6:6 [A.D. 401]).
"Our Lord…was not averse to males, for he took the form of a male, nor to females, for of a female he was born. Besides, there is a great mystery here: that just as death comes to us through a woman; that the devil, defeated, would be tormented by each nature, feminine and masculine, as he had taken delight in the defection of both." (Christian Combat 22:24 [A.D. 396].
"Having excepted the holy Virgin Mary, concerning whom, on account of the honor of the Lord, I wish to have absolutely no question when treating of sins—for how do we know what abundance of grace for the total overcoming of sin was conferred upon her, who merited to conceive and bear him in whom there was no sin?—so, I say, with the exception of the Virgin, if we could have gathered together all those holy men and women, when they were living here, and had asked them whether they were without sin, what do we suppose would have been their answer?" (Nature and Grace 36:42 [A.D. 415]).
Timothy of Jerusalem
"Therefore the Virgin is immortal to this day, seeing that he who had dwelt in her transported her to the regions of her assumption" (Homily on Simeon and Anna [A.D. 400]).
Gregory of Tours
"The course of this life having been completed by blessed Mary, when now she would be called from the world, all the apostles came together from their various regions to her house. And when they had heard that she was about to be taken from the world, they kept watch together with her. And behold, the Lord Jesus came with his angels, and, taking her soul, he gave it over to the angel Michael and withdrew. At daybreak, however, the apostles took up her body on a bier and placed it in a tomb, and they guarded it, expecting the Lord to come. And behold, again the Lord stood by them; the holy body having been received, he commanded that it be taken in a cloud into paradise, where now, rejoined to the soul, [Mary’s body] rejoices with the Lord’s chosen ones and is in the enjoyment of the good of an eternity that will never end" (Eight Books of Miracles 1:4 [A.D. 584]).
Gregory of Tours
"But Mary, the glorious Mother of Christ, who is believed to be a virgin both before and after she bore him, has, as we said above, been translated into paradise, amid the singing of the angelic choirs, wither the Lord preceded her" (ibid., 1:8).
John the Theologian
"[T]he Lord said to his mother, ‘Let your heart rejoice and be glad, for every favor and every gift has been given to you from my Father in heaven and from me and from the Holy Spirit. Every soul that calls upon your name shall not be ashamed, but shall find mercy and comfort and support and confidence, both in the world that now is and in that which is to come, in the presence of my Father in the heavens’" (The Falling Asleep of Mary [A.D. 400]).
John the Theologian
"And from that time forth all knew that the spotless and precious body had been transferred to paradise" (ibid.).
