“…that early Christians, taught their Faith by the Apostles, wrote of a New Eve, Mary.”
St. Irenaeus (b. 2nd century; d. c 200) declared that Mary became “the cause of salvation, both to herself and the whole human race,” because “what the virgin Eve had bound fast through unbelief, this did the virgin Mary set free through faith.” (Against Heresies, Book III, cap. 22, 4)
“…and whosoever perverts the oracles of the Lord to his own lusts, and says that there is neither a resurrection nor a judgment, he is the first-born of Satan.[3] Wherefore, forsaking the vanity of many, and their false doctrines, let us return to the word which has been handed down to us from[4] the beginning; “watching unto prayer,”[5] and persevering in fasting; beseeching in our supplications the all-seeing God “not to lead us into temptation.” - St. Polycarp
Polycarp was converted to Christianity by Apostles, He is known as one of the Apostolic Fathers.
St. Irenaeus was a disciple of St. Polycarp.
Ergo; St. Irenaeus was taught by Apostles through this Apostolic Father.
“Stand fast, therefore, in this conduct and follow the example of the Lord,
'firm and unchangeable in faith, lovers of the brotherhood, loving each other,
united in truth,’ helping each other with the mildness of the Lord, despising no man.” - St. Polycarp
St. Polycarp’s concern was preserving and handing on intact the doctrines of the Faith.
From the Catechsim of the Catholic Church on what the Catholic Church teaches:
“You Did Not Abandon Him to the Power of Death”
410 After his fall, man was not abandoned by God. On the contrary, God calls him and in a mysterious way heralds the coming victory over evil and his restoration from his fall. This passage in Genesis is called the Protoevangelium (“first gospel”): the first announcement of the Messiah and Redeemer, of a battle between the serpent and the Woman, and of the final victory of a descendant of hers.
411 The Christian tradition sees in this passage an announcement of the “New Adam” who, because he “became obedient unto death, even death on a cross,” makes amends superabundantly for the disobedience of Adam. Furthermore many Fathers and Doctors of the Church have seen the woman announced in the Protoevangelium as Mary, the mother of Christ, the “new Eve.” Mary benefited first of all and uniquely from Christ’s victory over sin: she was preserved from all stain of original sin and by a special grace of God committed no sin of any kind during her whole earthly life.
“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.” Justin Martyr, Dialogue with Trypho, 100 (A.D. 155).
St. John the Apostle of our Lord died at Ephesus, in the third year of Trajan, 100 AD, the same year St. Justin Martyr was born.
St Polycarp was a disciple of St. John the Apostle.
