After the Bible, this IS the greatest book ever written. De Monfort admitted the Holy Ghost moved his hand while penning it.

I consider the Bible and the Catechism one and the same. God revealed Himself in the Scriptures and then gave His ordained Church the authority to interpret it as Heaven intended, so the Bible and the Catechism are really one book. The Church defining the Bible's meanings is absolutely essential in every way, so both books complete each other. Now, since there is no question as to the greatest book ever, we see a book here that introduces us to the New Ark of the Covenant. Mary is FIFTY PERCENT of Satan's eternal enemy in Genesis 3:15 - yes. The Woman and the Seed. Jesus AND Mary, were to be eternally at war with Lucifer, as God would have it. This book teaches us on so many different levels that the mother of the living God is with us today and how we need to have a devotion to Her to find Her Son, Jesus Christ, in the end. God created Mary for His own use, and to reject Her, to reject really getting to know and understand Her in every way, would be a delight to the demons in Hell who so fear Her. Satan's wish to diminish Her, tear Her down and cover Her up, is a diabolical plan, and it worked with the Protestant Reformation. This book was hidden away for 150 years!!! Yes, the Devil tried to silence the author and his book, but to no avail. I cannot imagine any other book that could teach us to love and honor Mary the way Jesus did any better than True Devotion To Mary. To bind ourselves closer to the New Ark is ABSOLUTELY CRUCIAL. God loves NOTHING else He has ever created MORE than the Virgin. NOTHING. Mary IS HIS GREATEST MASTERPIECE. This book really teaches us how to love Her in the deepest and best possible way. What else can I say?? Others may feel different books have the 2nd place spot, but for me, this book IS IT!
