Happy Feast Day of Our Lady of the Miraculous Medal!
From a Supplement to 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 of Our Lady of the Miraculous Medal.
