Justin Martyr was among the first to draw a parallel between Eve and Mary. This derives from his comparison of Adam and Jesus. In his Dialogue with Trypho, written sometime between 155 and 167, he explains:

He became man by the Virgin, in order that the disobedience which proceeded from the serpent might receive its destruction in the same manner in which it derived its origin. For Eve, who was a virgin and undefiled, having conceived the word of the serpent, brought forth disobedience and death. But the Virgin Mary received faith and joy, when the angel Gabriel announced the good tidings to her that the Spirit of the Lord would come upon her, and the power of the Highest would overshadow her: wherefore also the Holy Thing begotten of her is the Son of God; and she replied, 'Be it unto me according to thy word." And by her has He been born, to whom we have proved so many scriptures refer, and by whom God destroys both the serpent and those angels and men who are like him; but works deliverance from death to those who repent of their wickedness and believe upon Him.

It is possible that the teaching of Mary as the New Eve was part of the apostolic tradition rather than merely Justin Martyr's own creation. Irenaeus, bishop of Lyon, also takes this up, in Against Heresies, written about the year 182:

In accordance with this design, Mary the Virgin is found obedient, saying, "Behold the handmaid of the Lord; be it unto me according to your word." Luke 1:38 But Eve was disobedient; for she did not obey when as yet she was a virgin.... having become disobedient, was made the cause of death, both to herself and to the entire human race; so also did Mary, having a man betrothed, and being nevertheless a virgin, by yielding obedience, become the cause of salvation, both to herself and the whole human race. And on this account does the law term a woman betrothed to a man, the wife of him who had betrothed her, although she was as yet a virgin; thus indicating the back-reference from Mary to Eve,...For the Lord, having been born "the First-begotten of the dead," Revelation 1:5 and receiving into His bosom the ancient fathers, has regenerated them into the life of God, He having been made Himself the beginning of those that live, as Adam became the beginning of those who die. 1 Corinthians 15:20–22 Wherefore also Luke, commencing the genealogy with the Lord, carried it back to Adam, indicating that it was He who regenerated them into the Gospel of life, and not they Him. And thus also it was that the knot of Eve's disobedience was loosed by the obedience of Mary. For what the virgin Eve had bound fast through unbelief, this did the virgin Mary set free through faith.

During the second century, the Gospel of James was also written. According to Stephen J. Shoemaker, "its interest in Mary as a figure in her own right and its reverence for her sacred purity mark the beginnings of Marian piety within early Christianity".
