We must conclude that, being necessary to God by a necessity which is called "hypothetical", (that is, because God so willed it), the Blessed Virgin is all the more necessary for men to attain their final end. Consequently we must not place devotion to her on the same level as devotion to the other saints as if it were merely something optional.
Louis de MontfortNever will anyone who says his Rosary every day become a formal heretic or be led astray by the devil.
Louis de MontfortIf devotion to the Blessed Virgin is necessary for all men simply to work out their salvation, it is even more necessary for those who are called to a special perfection. I do not believe that anyone can acquire intimate union with our Lord and perfect fidelity to the Holy Spirit without a very close union with the most Blessed Virgin and an absolute dependence on her support.
