If devotion to the Blessed Virgin Mary is necessary for all men simply to work out there 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.
Mary alone found grace before God without the help of any other creature. All those who have since found grace before God have found it only through her.
-St. Louis Marie de Montfort.
