Roman Martyrology, March 21st

This Day, the Twenty-First Day of March

On Mount Cassino, the birthday of the holy abbot Benedict, who restored and wonderfully extended in the West the monastic discipline, which was almost destroyed. His life, brilliant in virtues and miracles, was written by Pope Saint Gregory.

At Alexandria, under the emperor Constantine and the governor Philagrius, the commemoration of the holy martyrs who were attacked and murdered by the Arians and the Gentiles whilst they were in the church on Good Friday.

The same day, the holy martyrs Philemon and Domninus.

At Catania, Saint Birillus, who was consecrated bishop by Saint Peter. After converting many Gentiles to the faith, in extreme old age he rested in peace.

At Alexandria, blessed Serapion, anchoret and bishop of Thmuis, a man of great virtue, who being forced into exile by the enraged Arians, went to Heaven.

In the territory of Lyons, the abbot Saint Lupicinus, whose life was resplendent with the luster of holiness and miracles.

And elsewhere in divers places, many other holy martyrs, confessors, and holy virgins.

V: All ye Holy Martyrs, pray for us
R: Thanks be to God
