Happy Feast Day of St. Margaret Mary Alacoque!
From The Saint Andrew Daily Missal with Vespers for Sundays and Feasts by Dom Gaspar Lefebvre, O.S.B., of the Abbey of St- André (Bruges, Belgium: Liturgical Apostolate of the Abbey of St-André, 1956), here is the beautiful Mass for the Feast Day of St. Margaret Mary Alacoque.
May the celestial patronage of this illustrious Spouse of Our Lord avail everyone of us unto a greater, more ardent love for the Sacred Heart of the same Divine Savior.
