What is the Traditional Latin Mass?
The Traditional Latin Mass is the Catholic Mass celebrated according to the Roman Missal promulgated by St. Pius V in 1570 and reissued by Blessed John XXIII in 1962. This form of Mass has come down to us with only slight and gradual changes from the time of St. Gregory the Great in the sixth century. It is distinct in many ways from the Mass celebrated according to the Roman Missal promulgated by Pope Paul VI in 1970.
