Mary's role as Co-Redemptrix (again this is not defined as De Fide dogma) is completely subordinate and entirely dependent on Christ's redemption and sacrifice. It is a cooperative role just as we are called to be "co-workers" with God in salvation (1 Cor 3:9; 2 Cor 5:20; 6:1 cf. Phil 2:12-13). In the sense previously defined, the primary meaning of Co-Redemptrix, that Mary cooperated in the Redemption through the Incarnation of Christ, there certainly is plenty of biblical support for the claim that Mary "with Christ redeemed mankind" (John 1:1,14; 3:16-17; 1 John 4:9-14). The Adam-Christ (Rom 5:12ff; 1 Cor 15:20ff) and Eve-Mary parallel is found throughout the early Fathers of the Church, from St. Justin Martyr (c. 150 AD) forward showing us the entire history of Christianity believed that "Mary with Christ redeemed" the human race. This important early belief is stated explicitly by St. Irenaeus:
"By disobeying, Eve became the cause of death for herself and for the whole human race. In the same way Mary, though she also had a husband, was still a virgin, and by obeying, she became the cause of salvation for herself and for the whole human race..." (St. Irenaeus, Against Heresies 3:22 c. 180 AD)
The RCC seems oblivious to the nearly incestuous shellac with which they tarnish the relationship between Christ and Mary. It is not only unScriptural and blasphemous, it's thoroughly unseemly.
Human suffering is not redemptive by ourselves alone, but ONLY because we as Christians are united to Christ as part of his saving body, the branches in the vine (John 15:1-8). The Blessed Virgin Mother of God, as the preeminant saint and member of the Church, by her loving obedience and cooperation in the Incarnation, by her sufferings at the cross, and by her present prayer and intercession in heaven, has indeed brought salvation to the body of Christ, and redemption to the whole world. This way she really is the Co-Redemptrix of humanity and Mediatrix of all graces.
I’m amazed to see Nestorian heresies revived in this thread.
Blasphemy.
"Look unto me, and be ye saved, all the ends of the earth: for I am GOD, and there is none else." -- Isaiah 45:22 "For there is one God, and one mediator between God and men, the man Christ Jesus" -- 1 Timothy 2:5
"None else."
For those with ears to hear and eyes to see.
