Roman Catholics seem to like to have this issue both ways. They want to give Mary all of the accolades and have the idols of her and prayers to her and when called on it they resort to something along the lines of what you've noted.
Mary is accorded far more to her in Roman Catholicism which is not recorded in the NT. Her titles, given by Roman Catholicism, do not start appearing until ~ 3rd century.
When I read things like this form St. Alphonsus de' Ligouri, a Roman Catholic bishop, who was declared to be a Doctor of the Church by Pope Pius IX in 1871, it is very difficult to accept what you say.
I've not seen any Roman Catholic denounce what he's said as being inaccurate.
Are you willing to denounce what he's written below? (bold and paragraph mine for emphais)
That is, O Lady, it is true that all the Saints desire our salvation, and pray for us; but the love, the tenderness, that thou showest us in Heaven, in obtaining for us, by thy prayers, so many mercies from God, obliges us to acknowledge that in Heaven
we have but one Advocate,
and that is thyself, and that thou alone art truly loving and solicitous for our welfare.
The Glories of Mary, p 158 (google books)
No matter how many disclaimers you want to add this is in contradiction of the New Testament.
For there is one God, and one mediator also between God and men, the man Christ Jesus, 1 Timothy 2:5 NASB
He is also on record as quoting St. Bonaventure, "No one can enter Heaven unless by Mary, as though through a door."
There is nothing in the NT supporting this.
Liguori also writes: Thou art the dispenser of all graces, our salvation is in thy hands.
Again, there is nothing in the NT supporting this. In fact, it stands in contradiction of the NT.
Every good thing given and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shifting shadow. James 1:17 NASB
Are you willing to say what a Roman Catholic bishop, declared to be a Doctor of the Church, has written is wrong?
I can certainly understand why you would not be comfortable with the Fifth Marian dogma. But I predict it will be approved.
I agree with Pope Benedict XVI...the the formula “Co-redemptrix” departs to too great an extent from the language of Scripture and of the Fathers and therefore gives rise to misunderstandings.
That can be said for all of the Marian dogmas based on a study of Scripture.
The Church gives Mary a singular dignity above any other creature, that she is above all the saints. But the Church never puts Mary on an equal footing with God. Every thing she does comes from Him.
“The Glories of Mary” was written in this context. Liguori tells us that Jesus is the only mediator of justice between men and God, who in virtue of His merits can, and according to His promises will, obtain for us pardon and divine grace. He further states that the eternal Father has given us Mary for our advocate along with Jesus Christ. Her advocacy is only through Jesus Christ in His divine majesty, which dwells in Him as God.
So yes, Mary is regarded above any other human being. But the Church has never given her the same status as Jesus and the Holy Spirit. Without Jesus, Mary’s role does not exist.
