Month of Mary: Singular Vessel of Devotion

If 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.
