History of Gregorian Masses
Gregorian Masses take their name from Saint Gregory the Great, who was Pope in the 6th century. The Church has declared that the confidence of faithful Catholics in the effectiveness of the Gregorian Mass Serious is both reasonable and pious (Sacred Congregation for Indulgences of August 24, 1888). Tradition has it that then-Pope Gregory had a personal revelation from a deceased brother monk that his soul had been released from Purgatory upon the completion of thirty days of consecutive Masses said for the repose of his soul.
