Mary is the new Eve.
Let me start this by looking at the logic.
St. Paul describes Jesus as the new Adam in 1 Cor 15, reversing or undoing what Adam did
For since death came through a human being, the resurrection of the dead came also through a human being.For just as in Adam all die, so too in Christ shall all be brought to life (verse 21-22)
So, too, it is written, The first man, Adam, became a living being, the last Adam a life-giving spirit. (verses 48)
But there were two people involved in the fall Adam and Eve. So logically there should be a new Eve reversing or undoing what the original Eve did by her obedience to God. That person is Mary.
The early Fathers believed this. The earliest writing we have on this was Justin Martyr who said Christ became man by the Virgin, in order that the disobedience that proceeded from the serpent might receive its destruction in the same manner in which it derived its origin. For Eve 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
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. (Letter to Trypho 160AD).
Justin Martyr makes the point that Eve conceived the word of the serpent while Mary conceived the Word of God.
St. Iranaeus (140 202) says that just as Adam was the head of the old human race, so Jesus is the head of the new humanity. And, just as Adam had a collaborator in the person of Eve, so Jesus has a collaborator in the person of Mary. Mary is the Eve in Gods new creation. Writing in Against Heresies he says
In accordance with this design Mary the Virgin is found obedient, saying Behold the handmaid of the Lord, be it done unto me according to thy word. But Eve was disobedient; for she did not obey when she was yet a virgin. And even as she, having indeed a husband, Adam, but being as yet a virgin
having become disobedient was made the cause of death, both for herself and the whole human race; so also did Mary, having a man betrothed (to her), and being nevertheless a virgin, by yielding obedience, became the cause of salvation, both to herself and the whole human race.
For the main scripture on this we need to turn to St. Johns gospel. His gospel is very deep and mystical. John is supposed to have written this near the end of his very old age and so had many years to reflect and meditate on what he had seen and heard. He does not give lists of miracles but seven of what he calls signs. It is to the first of these the miracle at Cana that we must examine carefully as with Johns gospel we need to look below the surface.
There is an interchange between Mary and Jesus
When the wine ran short, the mother of Jesus said to him, They have no wine. (And) Jesus said to her, Woman, how does your concern affect me? My hour has not yet come. (Jn 2:3-4)
Protestant commentators see Jesus addressing Mary as Woman as a rebuke. But this is not. Jesus would never be so rude to his mother as to rebuke her, particularly in public. It would be breaking the 4th commandment. And Mary does not act as rebuked. He means something special by the term Woman. In fact one commentator says there is not one occasion in ancient literature of a son addressing his mother as Woman
And again he addresses her as Woman at the cross.
When Jesus saw his mother and the disciple there whom he loved, he said to his mother, Woman, behold, your son. (Jn 19:26). Is Jesus rebuking her there? No. Again, addressing her as Woman is significant. But I will come to that later.
It is how Eve is described in the Garden of Eden. She is always called Woman until after the fall. In this Jesus is indicating that Mary is the new Eve.
You may think this is just co-incidence but the beginning of Johns gospel has several parallel with the beginning of Genesis.
Firstly it begins with the same phrase In the beginning
. John seems to be deliberately drawing out attention back to the book of Genesis. Next in Genesis 1:3-5 God created light to shine in darkness. In John 1:4-5 we are told this life was the light of the human race;
the light shines in the darkness.
Then he counts off seven days, just as at the beginning of Genesis:
The next day (Jn 1:29)
The next day (Jn 1:35)
The next day (Jn 1:43) so now we are on the fourth day
On the third day there was a wedding in Cana (Jn 2:1) so the wedding feast was on the seventh day. John then stops counting days.
The seventh day in Genesis is the perfect day, the Sabbath, the sign of the Covenant (See Ex31:16-17). Therefore this wedding feast is going to be very significant. And indeed it is. I wont go into it all now. In the OT the wedding feast is the sign of Gods redemption his people. John is indicating that the new covenant that will be enacted at the Last Supper is being inaugurated.
The wedding feast is the first sign. Calvary is the seventh great sign, when Jesus is crucified and blood and water pour from his side. This is Jesus hour, the one that at Cana he said had not yet come. Again Mary is present and again Jesus addresses her as Woman.
When Jesus saw his mother and the disciple there whom he loved, he said to his mother, Woman, behold, your son. Then he said to the disciple, Behold, your mother. And from that hour the disciple took her into his home. (Jn 19:26-27)
This is not Jesus making domestic arrangements from the cross. Here Jesus is giving Mary as mother of all believers since beloved disciple represents all Jesus disciples (we are all beloved disciples). And we are to take Mary into our home- that is into our hearts.
Let us move forward to the book of Revelation and chapter 12 when we again come across a Woman:
A great sign appeared in the sky, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars.(Rev 12:1)
This woman is Mary. We know this is Jesus because verse 5 tells us the child she bears is a male child, destined to rule all the nations with an iron rod referencing psalm 2:9.
Now this woman, Mary, is the mother of those who keep Gods commandments and bear witness to Jesus (verse 17).
So at the cross and in Revelation Mary is referred to as the mother of all believers, just as Eve was referred to as the mother of all the living (Gen 3:20)
