“For as Eve was seduced by the word of an angel to flee from God, having rebelled against His Word, so Mary by the word of an angel received the glad tidings that she would bear God by obeying his Word. The former was seduced to disobey God, but the latter was persuaded to obey God, so that the Virgin Mary might become the advocate of the virgin Eve. As the human race was subjected to death through [the act of] a virgin, so it was saved by a virgin.” Irenaeus, Against Heresies, V:19,1 (A.D. 180).
“Under your mercy we take refuge, O Mother of God. Do not reject our supplications in necessity, but deliver us from danger,[O you] alone pure and alone blessed.” Sub Tuum Praesidium, From Rylands Papyrus, Egypt (3rd century).

“For it is said that he [Gregory the Wonderworker] heard the one who had appeared in womanly form exhorting John the Evangelist to explain to the young man the mystery of the true faith. John, in his turn, declared that he was completely willing to please the Mother of the Lord even in this matter and this was the one thing closest to his heart. And so the discussion coming to a close, and after they had made it quite clear and precise for him, the two disappeared from his sight.” Gregory of Nyssa, On Gregory the WonderWorker (A.D. 380).
“Mary, the holy Virgin, is truly great before God and men. For how shall we not proclaim her great, who held within her the uncontainable One, whom neither heaven nor earth can contain?” Epiphanius, Panarion, 30:31 (ante A.D. 403).
“Give milk, Mother to him who is our food, give milk to the bread coming down from heaven …give milk to him who made you such that he could be made fruitfulness in conception and in birth, did not take from you the ornament of virginity.” Augustine, Sermon 369:1 (A.D. 430).
“Hail to thee Mary, Mother of God, to whom in towns and villages and in island were founded churches of true believers.” Cyril of Alexandria, Homily 11 (ante A.D. 444).

“The Virgin’s festival (parthenike panegyris) incites our tongue today to herald her praise …handmaid and Mother, Virgin and heaven, the only bridge of God to men, the awful loom of the Incarnation, in which by some unspeakable way the garment of that union was woven, whereof the weaver is the Holy Ghost; and the spinner the overshadowing from on high; the wool the ancient fleece of Adam; the woof the undefiled flesh from the virgin, the weaver’s shuttle the immense grace of Him who brought it about; the artificer the Word gliding through the hearing.” Proclus of Constantinople, Homily 1 (ante A.D. 446).
