I think all this shows is that you still don’t (or won’t) understand Mary’s true place in the Catholic faith.
Mary is the purest realization of faith. As far as creatures created by God go, Mary is the most pure and sinless of them all. When we act out our faith, we realize it; Mary, by her submission to God’s will and purest devotion to her Son, has acted out or realized our faith better than anyone else. That’s all that the quoted statement means, it doesn’t mean mean that she is faith or truth. Jesus is truth, He tells us so in John 14:6. Mary leads people to her Son by her example, plain and simple.
Pope Pius XII’s quote is similarly describing how Mary’s role in the faith is to lead people to her Son by her purest example and intercession. But, Catholics consider* all *relevant text and not just single verses taken out of context, so let’s read the whole thing shall we (comments in normal font intersperced are mine)?
Pope Pius XII’s Prayer Recta Ratio:
Enraptured by the splendor of thy heavenly beauty, and impelled by the anxieties of the world, we cast ourselves into thine arms, O Immacuate Mother of Jesus and our Mother, Mary, confident of finding in thy most loving heart appeasement of our ardent desires, and a safe harbor from the tempests which beset us on every side.
Our heavenly mother Mary intercedes for us because God has given her that power, that’s what Pope Pius XII is invoking here.
Though degraded by our faults and overwhelmed by infinite misery, we admire and praise the peerless richness of sublime gifts with which God has filled thee, above every other mere creature, from the first moment of thy conception until the day on which, after thine assumption into Heaven, He crowned thee Queen of the Universe.
Amazing! This prayer states that Mary is a creature (not a goddess) that has been endowed by God with gifts above all other creatures, among which are sinlessness, assumption, and coronation. Mary didn’t crown herself queen of heaven, God did! Just as the Catholic Church teaches. Mary has this high place because God gave it to her; she didn’t get it from us Catholics here on Earth, though we recognize that she has it.
O crystal fountain of faith, bathe our minds with the eternal truths! O fragrant Lily of all holiness, captivate our hearts with thy heavenly perfume! O Conqueress of evil and death, inspire in us a deep horror of sin, which makes the soul detestable to God and a slave of Hell!
Now that we get the full context of the single line that you misrepresented, let look at is again. “O crystal fountain of faith” is indeed Mary, and the phrase’s imagery is being invoked for a purpose: “bathe our minds with the eternal truths!”. Pope Pius XII is asking Mary to help us know and understand the truth better. We know from John 14:6 that Jesus is truth - Mary, help us to know Jesus better. That’s what this is all about. And again, Mary only has the power to conquer evil and death because her Son equipped her thus.
O well-beloved of God, hear the ardent cry which rises up from every heart. Bend tenderly over our aching wounds. Convert the wicked, dry the tears of the afflicted and oppressed, comfort the poor and humble, quench hatreds, sweeten harshness, safeguard the flower of purity in youth, protect the holy Church, make all men feel the attraction of Christian goodness. In thy name, resounding harmoniously in Heaven, may they recognize that they are brothers, and that the nations are members of one family, upon which may there shine forth the sun of a universal and sincere peace.
A beautiful way of asking Mary to intercede with God on our behalf. Are you seeing a pattern here?
Receive, O most sweet Mother, our humble supplications, and above all obtain for us that, one day, happy with thee, we may repeat before thy throne that hymn which today is sung on earth around thine altars: Thou art all-beautiful, O Mary! Thou art the glory, thou art the joy, thou art the honor of our people!
Amen.
In order for Mary to receive our supplications (prayers), we have to give them. And again, Mary is allowed to share in the glory, joy, and honor of her Son, she doesn’t merit it of her own accord. In fact, everyone in Heaven is allowed to share in the glory, joy, and honor of God, not just Mary.
Please disagree with what Catholics really believe, not what you think we believe.
Happy feast of the Immaculate Conception everyone! Thank you Mary for all of your aid, please continue to help us sinners get closer to your Son so that we may be with you both forever.
