Stick to saying Mary was the Second Eve. At least it has some scriptural parallel in Jesus Christ as the second Adam.
Abrahm was an astrologer and worshipped strange gods prior to his becoming Abraham. The theology just doesn't hold up to scrutiny.
Apparently Abraham was okay in God’s book: See Luke 13: 28, Luke 16: 22-29, Luke 19:9, John 8:39, John 8: 56.
Mary is the second Abraham: she was the new Ark of the New Covenant, she held the Word inside her, was completely blameless, was completely obedient, found great favor with God, went beyond Abraham’s willingness to sacrifice his son to actually accepting God’s will and watching her son actually sacrificed, and faithfully walked with our Savior every step of His journey. Christ started his public ministry of redemption at her request with the miracle at Cana. She was at the foot of the cross with Him. Her spiritual children outnumber the stars.
No other human participated in Christ’s mission as completely as Mary did. I worship God— but I honor Mary as the greatest human who ever lived. She is completely God’s and her last words to us, as told to us by the Holy Spirit, are, “Do whatever He tells you.” What’s not to love about Mary!?! She is a perfect example of how a human being can love God.
Eve’s sin, the first sin, was greater than Adam’s. It is only just that Mary, a woman, was the human who contributed most to God’s plan for our salvation. God made all things new and settled all accounts.
