Roman Martyrology-August 15th- on this date in various years-
The Assumption of the most holy Virgin Mary, Mother of God.
At Cracow in Poland, St. Hyacinth, confessor of the Order of Preachers, whom Pope Clement VIII placed in the number of the saints. His feast is observed on the 17th of August.
At Alba Regalis in Hungary, St. Stephen, King of Hungary, who was graced with divine virtues, was the first to convert the Hungarians to the faith of Christ, and was received into heaven by the Virgin Mother of God on the very day of her Assumption. By decree of Pope Innocent XI, his feast is kept on the 2nd of September, on which day the strong city of Buda, by the aid of the holy king, was recovered by the Christian army.
At Rome, on the Appian Way, St. Tarsicius, acolyte. The pagans accosted him as he was carrying the Sacrament of Christ’s Body, and began to inquire what it was. But he judged it an unworthy thing to cast pearls before swine. They therefore beat him with sticks and stones until he expired. The sacrilegious searchers examined his body, but found no vestige of the Sacrament of Christ, either in his hands or in his clothes. The Christians took up the body of the martyr, and buried it reverently in the cemetery of Callistus.
At Tagaste in Africa, St. Alipius, bishop, who was the disciple of blessed Augustine, and the companion of his conversion, his colleague in the pastoral charge, his valiant fellow-soldier in disputing heretics, and finally his partner in the glory of heaven.
At Soissons in France, St. Arnulf, bishop and confessor.
At Rome, St. Stanislas Kostka, a native of Poland, confessor of the Society of Jesus, who being made perfect in a short time, fulfilled a long time by the angelic innocence of his life. He was inscribed on the list of the saints by the Sovereign Pontiff, Benedict XIII.
And elsewhere in divers places, many other holy martyrs, confessors, and holy virgins.
R. Thanks be to God.
