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.
At Antioch, St. Anastasius, bishop and martyr. During the reign of Emperor Phocas he was cruelly murdered by Jews in a riot which they had instigated against the Christians.
At Nicomedia, St. Glycerius, priest. During the persecution of Diocletian he was subjected to many torments, and finally fulfilled his martyrdom by being cast into the flames.
In Tuscany, the holy martyrs John and Festus.
In Lycia, St. Themistocles, martyr. In the reign of Emperor Decius, he offered himself to take the place of Dioscorus, whom they were seeking to slay. He was tortured on the rack, dragged over rough ways and scourged, and thus obtained the crown of martyrdom.
At Treves, St. Severinus, bishop and confessor.
And elsewhere in divers places, many other holy martyrs, confessors, and holy virgins.
R. Thanks be to God.
