Happy Feast Day of St. Gerard Majella!
From a Supplement containing the proper Masses for the Feasts observed throughout the Dioceses of Canada, found in The Saint Andrew Daily Missal with Vespers for Sundays and Feasts by Dom Gaspar Lefebvre, O.S.B., and the Monks of the Abbey of St. Andrew (Saint Paul, MN: The E. M. Lohmann Co., 1959), here is the Mass for the Feast of Saint Gerard Majella.
