GraceDK - the way you answer posts makes it impossible to quote you, so I’ve copied your post here.
You’ve answered your own question. Mary was conceived without sin and remained sinless for her entire life. That means she was completely at one with the Holy Trinity. There is absolutely no stretch there at all. Being completely without sin means being completely at one with God the Father, Son and Holy Spirit. No sin means no separation. That could not be said about any other human being except our Lord, of course, because everyone else was born with original sin. When we pray “Hail Mary, full of grace”, those are not just words. Mary was always completely filled with grace. That means she was never stained with sin. She was always in union with God. That is basic teaching of the Church.
Yes, of course, ultimately all salvation is from our Lord. No one here or anywhere else is saying salvation is from Mary. Here is a very good explanation from
catholicbible101.com:
In the last book of the Bible, Revelation (or Apocalypse), in the 12th chapter, there is a huge battle going on (enmity) between Mary, the woman clothed with the sun who gives birth to a savior, and the devil. The devil tries to take her out, but God miraculously rescues her and her child by putting them into the desert, away from Herod’s evil clutches. Revelation 12:17 says that we are her children if we obey the commandments and bear testimony to her son, Jesus. **This is a great bookend to the Garden of Eden, where an immaculately created virgin, Eve, says yes to the demon Lucifer, and allowed sin to enter the world. **
Mary, also an immaculately created virgin, says yes to the angel Gabriel, and allowed salvation to enter the world. Eve came out of Adam, Jesus came out of Mary.
It was through Mary that Christ came into the world and through her (again, not from her) that he brings salvation to the world and crushes the head of Satan.
There can be speculation about Enoch and Elijah, but there is no definite teaching on it, as jwinch2 pointed out. It is dogma of the Church that Mary was assumed into heaven body and soul and that is not taught about anyone else, of course with the exception of our Lord.
The Catholic Church has put her imprimatur on everything St. Louis de Montfort wrote. He is considered the authority on Marian devotion and as I have posted, he is up as a candidate for doctor of the church. You may think whatever you want to think, but all of his writings have the full approval of the Catholic Church. His cannonization took over 200 years, and if you wish to read about it, you can go
here. Here is just one excerpt from that about the examination of his writings:
Finally, on May 7, 1853, it was made public that the deliberations of the congregation had revealed nothing in the writings of Montfort that constituted an obstacle to the pursuit of his cause. The Holy Father approved and confirmed this rescript of the Sacred Congregation on May 12, 1853.
That means there is nothing in St. Louis de Montfort’s writings that go against church teaching including the quote that “It was through the blessed Virgin Mary that Jesus Christ came into the world, and it is also through her that he must reign in the world.”
