So I beleive the question really is what is a sound devotion to Our Blessed Mother Mary?
The way I understand it is, we have to have a sound devotion to our Blessed Mother Mary in order for it to lead us to Jesus Christ.
I’ll preface this with one more question -
why have a devotion to Mary?
Please do not get me wrong. I do agree with St. Louis that devotion to Mary is necessary, simply and solely because it is a way of reaching Jesus perfectly, loving him tenderly, and serving him faithfully.
Why can we not reach Jesus perfectly? Montfort gives us these points in paragraph 25:
God the Holy Spirit entrusted his wondrous gifts to Mary, his faithful spouse, and chose her as the dispenser of all he possesses, so that she distributes all his gifts and graces to whom she wills, as much as she wills, how she wills and when she wills.
What is his rationale for this? None given. It is proof by assertion. He
teases that he
could offer proofs such as Father Poiré’s “Triple Crown of the Blessed Virgin” but it appears that work has been lost to history. After Montfort, we see profound influence in Popes such as Leo XIII, Paul VI, and John Paul II, through whom the vast majority of Marian doctrine has come. This means that this role of Mary in salvation is relatively new in the Church.
If you look back at the early doctors, you do not see such accolades universally poured upon Mary. While John Damascene and Ephraim of Syria trumpet Mary’s intercession, Augustine limits it. Irenaeus, Clement of Rome, Ignatius of Antioch, don’t even mention Mary outside of Scripture. But where Montfort cites Augustine or Irenaeus he takes them in a different character than those I think the authors themselves intended. I was astounded to find that Paul VI had misquoted Irenaeus, but it turns out he took the interpretation wholesale from Montfort.
I’ll be honest, I can only read so much of Montfort before it strikes me as so much blasphemy. Louis gives lip-service to Christ but the entire focus of his True Devotion is Mary, going so far as to say there are true and false kinds of devotion to Mary. He reinterprets Scripture to point it towards Mary. He even presumes things that the writers of Scripture themselves did not know. His writings are novel - neodoxy - even he says so:
My heart has dictated with special joy all that I have written to show that Mary has been unknown up till now
If God gives Mary all graces to dispense as she wills, then why do we need God?
If Mary perfectly conforms her will to God’s so that her will and the Will of God are indistinguishable, then why do we need Mary? Does she cease to be a separate being? As such, does Montfort allow us to move from hyperdulia to true worship as far as Mary is concerned?
And why does Jesus Christ, Lord and Savior, Uncreated and Eternal, need a
distributor for the Grace of which He is the Source?
My honest opinion is this: Marian devotion, rightly practiced, isn’t devotion at all but co-worship with Mary of Jesus. Mary should never be the target. She kneels as the handmaiden, and we kneel alongside her but not in front of her. The dogmas are taken out of proportion in practice.
To say Mary is Queen of Heaven because she is the mother of the Son is one thing. To say that she commands armies of angels is quite another.
To say that Mary is mediatrix of all graces because Jesus Christ, the source of all Grace, was born in flesh through Mary’s body is one thing. To say that Mary has been appointed with special powers of distribution in Heaven is quite another.
To say that Mary is co-redemptrix in the same way that all who share the Gospel and exhort to a living faith in Christ are co-redeemers is one thing. To say that one cannot reach Christ without Mary in the current sense - not just that Mary is necessary for Christ’s birth but directly for every sinner’s individual redemption - is quite another.
