Have you ever heard someone refer to Our Lady as “The New Eve” and wonder what they were talking about?
To find out why Catholics refer to Mary as the New Eve, we have to start at the very beginning: Genesis. Eve, the wife of Adam, became the "mother of all the living," we read in Genesis 3:20. Because of Adam and Eve's disobedience to God, sin and death entered the world, and all of Eve's children are born in original sin.
But Mary’s role in salvation history beautifully illustrates how God makes all things new. Through the obedience of Mary, the handmaid of the Lord, Jesus Christ entered the world as man to reverse the disobedience of Adam and Eve.
So not only can we call Mary the “New Eve,” we can consider Christ the "New Adam."
Christ, the Son of Mary, offers a new life of grace to all who believe in Him. All who accept Christ's invitation become His brothers and sisters, and become the spiritual children of Mary, the New Eve.
Many Fathers of the Church clearly saw the connection between Eve and Mary, and would frequently claim: "death through Eve, life through Mary."
Much more recently, Pope Paul VI wrote in his Credo of the People of the God in 1968: "We believe that the Holy Mother of God, the New Eve, Mother of the Church, continues in heaven to exercise her maternal role on behalf of the members of Christ."
