Gregorian Masses are a series of Holy Masses traditionally offered on 30 consecutive days as soon as possible after a person’s death. They are offered for an individual soul.
This series of 30 Masses, known as “Gregorian Masses”, derives its name from Pope St. Gregory the great (590-604). It is in his writings (Dialogues) we read that after offering 30 Masses consecutively for the repose of the soul of a monk, the deceased made known his deliverance from Purgatory.
This custom of offering the 30 Gregorian Masses spread throughout the entire Catholic world and still continues today. The Sacred Congregation of Indulgences has declared the tradition to be “a pious and resonable belief of the faithful”
These Masses may be offered for only one departed soul whose speedy entrance into heaven is sought through Divine Mercy. The “Gregorian Masses” cannot be offered for a person still living.
The requested stipend for a set of these Masses is $500. “The Gregorian Masses” that are requested are directed to the Shrine of Our Lady of Czestochowa in Poland.
