PET: The Catholic Church says it was Christ.
No, it doesn't. As the link showed, the RCC says Christ and Mary paid for men's sins and together they bought God's elect by their individual sufferings, each through their own "cross."
As Christ said, "by thy words thou shalt be condemned" (Matt. 12:37)
The Catholic Church does NOT say this, and the link does NOT show this.
I don't really want to jump into your convo here, but I want to point something out for any Lurkers who may be watching this thread. The link is to another thread on FR, an article written by a single Priest concerning Padre Pio and the proposed title of "Co-redemptrix." In no way is it an authoritative Church document.
Now we get to watch the ducking and back-tracking
Telling Catholics what they believe has always been a failing of protestants. Repeating a lie about Catholic beliefs does not make it any more true the thousandth time than the first.
But, thanks for repeating it. Just gives the Catholics one more chance to show protestant lies for what they are.
2. The recourse we have to Mary in prayer follows upon the office she continuously fills by the side of the throne of God as Mediatrix of Divine grace; being by worthiness and by merit most acceptable to Him, and, therefore, surpassing in power all the angels and saints in Heaven. Now, this merciful office of hers, perhaps, appears in no other form of prayer so manifestly as it does in the Rosary. For in the Rosary all the part that Mary took as our co-Redemptress comes to us, as it were, set forth, and in such wise as though the facts were even then taking place; and this with much profit to our piety, whether in the contemplation of the succeeding sacred mysteries, or in the prayers which we speak and repeat with the lips.
