Roman Martyrology-December 21st-on this date in various years-
At Mylapore, the birthday of the blessed Apostle Thomas, who preached the Gospel to the Parthians, Medes, Persians, and Hyrcanians. Having finally penetrated into India, and instructed those nations in the Christian religion, he died pierced with lances at the order of the king. His remains were first taken to the city of Edessa in Mesopotamia, and then to Ortona.
At Fribourg in Switzerland, the birthday also of St. Peter Canisius, priest of the Society of Jesus, a confessor famed for his sanctity and learning. He defended and spread the Catholic faith with the utmost zeal in Germany during its most difficult times. Pope Pius XI added him to the list of the saints, and at the same time declared him to be a doctor of the universal Church, appointing his feast to be observed on the 27th of April.
