No, that has nothing to do with what Paul said.
Actually, it does. The principle is that just like Paul can save some (even though it is only Jesus that saves), we can say Mary or even you or me save some in the sense that he/we/she can bring Jesus Christ to others.
Let us look at this again:
"Since faith is the foundation, the source, of the gifts of God by which man is raised above the order of nature and is endowed with the dispositions requisite for life eternal, we are in justice bound to recognize the hidden influence of Mary in obtaining the gift of faith and its salutary cultivation - of Mary who brought the "author of faith" into this world and who, because of her own great faith, was called 'blessed.' 'O Virgin most holy, none abounds in the knowledge of God except through thee; none, O Mother of God, attains salvation except through thee; none receives a gift from the throne of mercy except through thee" (ADIUTRICEM (On the Rosary), Encyclical of Pope Leo XIII, promulgated on September 5, 1895).
You should actually read the entire letter in its context. The Pope is recommending devotion to Mary and praying the rosary. But he also says "Let each one weigh for himself, moreover, how fitting is this practice and how fruitful to himself;"... In other words, each person can decide for themselves whether or not they want to pray the rosary or not. Catholics are not required to pray the rosary or have a certain level of devotion to Mary. His words here are not binding on Catholics in the sense that he is making an infallible statement on faith and morals that he intends to be binding on all Christians.
No one is saved apart from "faith." And what the church of Rome says in the above quote makes it plain that no one can have the knowledge of God which comes as a result of "faith" EXCEPT THROUGH MARY."
Because our faith is placed in Jesus who came through Mary. The letter makes that pretty clear when it says:
"we are in justice bound to recognize the hidden influence of Mary in obtaining the gift of faith and its salutary cultivation-of Mary who brought the "author of faith"
It is through Mary that we can receive the gift of faith because it is through her that the "author of faith" (Jesus) came to us.
It cannot be denied that Rome teaches that no one without exception can be saved apart from Mary.
Well, without Mary we don't have Jesus, do we? In that sense, yeah.
In the sense that Mary can save us without Jesus? No way. And the Church doesn't teach that.
Would you please comment on paragraph 432 from the Catechism? You seem to be ignoring that.
Rome's teaching even is worse than that when we consider what that church teaches here:
"As she suffered and almost died together with her suffering and dying Son, so she surrendered her mother's rights over her Son for the salvation of the human race. And to satisfy the justice of God she sacrificed her Son, as well as she could, so that it may justly be said that she together with Christ has redeemed the human race" ( The Church Teaches, Documents of the Church in English Translation, by the Jesuit fathers of St. Mary's College).
Assuming that that is official Church teaching, I don't see how that is saying anything other than: Mary cooperated with God's plan as best she could and in that sense it can be said she saves some.
That is the same thing Paul is talking about in 1 Corinthians 9.
Tell me, how can Paul say that he saves some because he brings Jesus Christ to others and cooperates with God's plan (that's what he was doing, after all) but then we can't say the same thing about Mary when she brings Jesus Christ to the world and cooperates with God's plan in an even fuller sense?
The Scriptures make it plain that redemption only comes as a result of the Lord Jesus' death upon the Cross and Mary did not die upon the Cross:
The Catechism of the Catholic Church plainly teaches the exact same thing:
"Christ paid the price of His own sacrificial death on the cross to ransom us, to set us free from the slavery of sin, thus achieving our redemption." (Catechism of the Catholic Church pg.896)
Omigosh, give me a break. Have you ever met anyone in your life that believes Mary died on the cross for our sins? You obviously are very confused about Catholic teaching if you think Catholics think Mary is a Saviour in the sense that Jesus Christ is our Savior. No Catholics believe that. The Church has never taught that. You are misreading certain Catholic writings and coming to false conclusions.
Address paragraph 432 of the Catechism please. It clearly shows that what you
think the Church teaches...she actually
doesn't teach.
"Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot" (1 Pet.1:18-19).
It is not true that Mary, together with Christ, has redeemed the human race! Anyone with the least bit of spiritual discernment knows that what Rome teaches about Mary is false.
Or....you are misunderstanding what the Catholic Church really teaches. Which is the case.
You know, there are free online Catechism's of the Catholic Church where you can actually see what the Church really teaches for yourself.
Last thing: How can Paul say "I might by all means save some." ?
Paul didn't die on the cross, after all.
Peace.
