Calling Mary coredemptrix is not saying she was not one of the redeemed.
First it would help if an agreement of what is meant by Co redeemer is met. Here is the explanation given by those who support the title of Coredemptrix. Keep in mind also that it is not official Catholic doctrine. And as such does not have to be believed by the faithful.
“When the Church invokes Mary under the title, “Coredemptrix”, she means that Mary uniquely participated in the redemption of the human family by Jesus Christ, Our Lord and Saviour. At the Annunciation (cf.Lk.1:38) Mary freely cooperated in giving the Second Person of the Trinity his human body which is the very instrument of redemption, as Scripture tells us: “We have been sanctified through the offering of the body of Jesus Christ once for all” (Heb.10:10).
And at the foot of the cross of our Saviour (Jn.19:26), Mary’s intense sufferings, united with those of her Son, as Pope John Paul II tells us, were, “also a contribution to the Redemption of us all” (Salvifici Doloris, n.25). Because of this intimate sharing in the redemption accomplished by the Lord, the Mother of the Redeemer is uniquely and rightly referred to by Pope John Paul II and the Church as the “Coredemptrix.”
It is important to note that the prefix “co” in the title Coredemptrix does not mean “equal to” but rather “with”, coming from the Latin word cum. The Marian title Coredemptrix never places Mary on a level of equality with her Divine Son, Jesus Christ. Rather it refers to Mary’s unique human participation which is completely secondary and subordinate to the redeeming role of Jesus, who alone is true God and true Man.”
“Jesus Christ as true God and true man redeems the human family, while Mary as Coredemptrix participates with the Redeemer in his one perfect Sacrifice in a completely subordinate and dependent way. The key word here is “participation” in that which is exclusively true of Jesus Christ. The title “Coredemptrix” never puts Mary on a level of equality with our Lord; rather, it refers to Mary’s unique and intimate participation with her divine Son in the work of redemption. “Coredemptrix” is a Latin word; the prefix “co” in the title, “Coredemptrix,” derives from the Latin word “cum,” which means “with,” not “equal to.” Mary’s sufferings are efficacious towards the redemption of man because they are wholly rooted in the redemptive graces of Christ and are perfectly united to His redeeming will.”
Catholics do agree wholeheartedly that Jesus is the one and only mediator between man & God. No question ... the bible teaches this ... the Catholic Church teaches this. No subordinate co-deities, no additional redeemers, no additional mediators! Clear enough?
“But what about our role in bringing people to Christ, preaching the Gospel, as teachers, pointing people to Christ .... and so on? We can be mediators in that fashion. Surely you do not disagree that faith comes from (by grace) from receiving the gospel message.”
The idea of Mary as Coredemptrix acknowledges her unique role in the plan of salvation. All Christians have a role. In preaching the Gospel it is to be hoped that sinners will hear and come to Christ. If you or I preach that Gospel and the grace of the Lord is answered by that sinner, which is given the greater Glory? Our preaching or the Gospel? I say the Gospel.
Personally I think that such a title should remain a personal and pious devotion and not become doctrine. However the Holy Spirit does not give me the charism of infallibility so should it become doctrine I will submit to Mother Church. Of whom Christ promised the gates of hell would not prevail. Oh I admit at times they sure nuff do place holes in the defenses and at times even crumble parts of the fortress. But Christ is good and His promise is all.
A lot of people “uniquely” participated in the redemption.
Judas did, Pilate did too.
So did Joseph, and Simon of Cyrene.
That doesn’t make them co-redeemers, nor does what Mary did make her co-redeemer.
I am glad you posted that, but it will mean nothing to the Catholic-haters who come here playing “The Game.”
After all, in the Game, it is THEY who decide what Catholics believe, even down to the meaning of individual words. Pointing out the bankruptcy of their position only returns cries of “Spin! Spin! Spin!”
Some of them can be observed here keeping score.
