Roman Martyrology-March 21st-on this date in various years-
At Monte Cassino, the birthday of the holy abbot St. Benedict, who restored and wonderfully extended the monastic discipline in the West, where it had almost been destroyed. His life, brilliant in virtues and miracles, was written by Pope St. Gregory.
At Catania, St. Birillus, who was consecrated bishop by St. Peter. After converting many gentiles to the faith, he died in extreme old age.
At Alexandria, under Emperor Constantine and the governor Philagrius, the commemoration of the holy martyrs who were murdered by the Arians and the heathens, being attacked by them while they were in church on Good Friday.
On the same day, the holy martyrs Philemon and Domninus.
At Alexandria, blessed Serapion, anchoret and bishop of Thmuis, a man of great virtue, who was driven into exile by the enraged Arians, where he departed to heaven.
In the territory of Lyons, St. Lupicinus, abbot, whose life was brilliant with the glory of holiness and miracles.
In the village of Ranft, near Sachseln in Switzerland, St. Nicholas of Flue, a family man who became an anchoret, famed for his most ardent penitence and contempt for the world, and known by the Swiss as the father of the fatherland. He was numbered among the saints by Pope Pius XII.
And elsewhere in divers places, many other holy martyrs, confessors, and holy virgins.
R. Thanks be to God.
