Roman Martyrology-June 21st- on this date in various years-
At Rome, St. Aloysius Gonzaga, cleric of the Society of Jesus and confessor, most renowned for his contempt of the princely dignity and the innocence of his life. Pope Benedict XIII placed him on the canon of the saints as special protector of young students; Pope Pius XI confirmed this and again solemnly declared him to be the heavenly patron of all Christian youth.
Also at Rome, St. Demetria, virgin, daughter of the holy martyrs Flavian and Dafrosa, and the sister of St. Bibiana, virgin and martyr. She was crowned with martyrdom under Julian the Apostate.
The same day, St. Eusebius, bishop of Samosata. In the time of the Arian emperor Constantius, he disguised himself in military dress and visited the churches of God to confirm them in the faith. He was banished into Thrace by Valens, but when peace was restored to the Church in the reign of Theodosius, he was recalled. When he again visited the churches, an Arian woman threw a tile down upon him, which fractured his skull and made him a martyr.
At Iconium in Lycaonia, St. Terence, bishop and martyr.
At Syracuse in Sicily, the birthday of the holy martyrs Rufinus and Martia.
In Africa, the holy martyrs Cyriacus and Apollinaris.
At Mainz, St. Alban, martyr, who was made worthy of the crown of life, after long labors and severe combats.
At Pavia, St. Ursiscenus, bishop and confessor.
At Tongres, St. Martin, bishop.
In the parts of Evreux, St. Leutfrid, abbot.
And elsewhere in divers places, many other holy martyrs, confessors, and holy virgins.
R. Thanks be to God.
