And, for the record, I don't think what you say adds up. You're claiming that Catholics say Christ did not pay the penalty for sin and then you quote:
It was by this inward sacrifice of obedience unto death, by this perfect love with which He laid down his life for His friends, that Christ paid the debt to justice, and taught us by His example,
Part of our estrangement from God is not knowing who Hs is or what He wants (at least no in sufficient detail). Consequentlypart of atonement will be exemplary
I'm not disparging anyone. I'm simply stating what is the current view of the Catholic Church. Catholics do not believe in the blood atonement of Christ so there is no need for Mary to have had her "debt of sin" paid. Christ dead showed us what true love and obedience is all about. This is very similar with the Orthodox view.
I have given you a reference to the Catholic website of NewAdvent on the Atonement in the above post so that you can read it for yourself. Don't yell at me.
