In the Secret of Mary by Louis D Montfort, he writes:
48. 3. We must never go to our Lord except through Mary, using her intercession and good standing with him. We must .
49. 4. We must perform all our actions for Mary, which means that as slaves of this noble Queen we will work only for her, promoting her interests and her high renown, and making this the first aim in all our acts, while the glory of God will always be our final end. In everything we must renounce self- love because more often than not, without our being aware of it, selfishness sets itself up as the end of all we work for. We should often repeat from the depths of our heart: "Dear Mother, it is to please you that I go here or there, that I do this or that, that I suffer this pain or this injury."
50. Beware, chosen soul, of thinking that it is more perfect to direct your work and intention straight to Jesus or straight to God.
Without Mary, your work and your intention will be of little value. But if you go to God through Mary, your work will become Mary's work, and consequently will be most noble and most worthy of God.

By spreading devotion to the Blessed Virgin Mary, St Louis De Montfort was teaching souls to love the devil's greatest enemy. [In True Devotion to Mary , he states that the devil fears Mary more than all Angels and men,
and in a sense more than God Himself.
De Montfort's writing was examined by the Holy See, which pronounced there was nothing in them to hinder his beatification and canonization. https://archive.org/details/TheSecretOfMary
All of this is contradicted by the New Testament. The catholic cannot defend this with any Scripture.
To claim Satan fears Mary, a created being, more than God Himself, the Creator of all, is, well....words fail to explain this blasphemy.
The blasphemy of the catholic church on mary is beyond measure. And the catholic insists they do not pray to hear as if she were God.
An appeal to the truth found in the New Testament is required to clear up this false roman catholic teaching.
5Thomas said to Him, “Lord, we do not know where You are going, how do we know the way?”
6Jesus said to him, “I am the way, and the truth, and the life; no one comes to the Father but through Me. John 14:5-6 NASB
Jesus makes it clear in His reply to Thomas that He is the only way to the Father. The Greek is emphatic in v6 on this. He is the only way.
He does not set a qualification on going through Mary or anyone else. If the catholic wants to insist otherwise they are at odds with Christ Himself.
ealgeone:
Louis D. Monfort is a spiritual writer and theologian, and that is his theological opinion. There are a diversity of spirituality traditions and devotions within the Catholic Church. One could never Pray the Rosary in ones life and still be an orthodox Catholic. Nobody is required to pray the Rosary are have a Marian Spirituality, for the record. The last 3 Popes, all have a devotion to Mary, albeit in different ways. I would say Pope Benedict’s spirituality was more formed by Saint Augustine and Saint Bonvanenture(Patristic and Scholastic theology, but with a more private devotion to Mary). Pope John Paul II had perhaps more of public devotion to Mary, probably prayed the Rosary every day. Pope Francis seems to have a spirituality based on Saint Ignatius (founder of the Jesuits) and by his name Francis, Saint Francis of Assisi.
And yes Louis D. Montfort is a Saint and has a strong Marian Devotion, but not every Catholic has a Marian devotion to his level, neither of the previous 3 Popes did, so while yes he is a Saint, everything one theologian and spiritual writer writes while it may not be in direct conflict with Defined Doctrine, it also does not mean that everything a canonized Saint writes is the only way to express the faith.
And again, what he is writing about is intercessory prayer, prayer with and in communion with Mary to God. There is nothing wrong with that.
