Pius, the first of that name, the son of Rufinus, was from Aquilia, and was a priest of the holy Roman Church when he was made Supreme Pontiff. He lived under the Emperors Antoninus Pius and Marcus Aurelius. He held five ordinations in the month of December, wherein he ordained twelve bishops and eighteen priests. There remain several eminent ordinances of his, notably that which ruleth that the Resurrection of the Lord be not observed upon any day of the week save Sunday. He turned the house of Pudens into a church, and on account of its eminence above the other churches, as being that where the Bishop of Rome dwelt, he dedicated it under the name of the Shepherd. Here he often celebrated, and baptized and numbered among the faithful many converts to the faith. While he strove to do the work of a good shepherd he shed his blood for his sheep, and for the chief Shepherd Christ. He was crowned with martyrdom upon the 11th day of July, and buried upon the Vatican Hill.

St Pius I governed the Church in the middle of the 2nd century during the reigns of the Emperors Antoninus Pius and Marcus Aurelius. He was the ninth successor of Saint Peter. He decreed that Easter should only be kept on a Sunday. Although being credited with ordering the publication of the Liber Pontificalis, compilation of that document was not started before the beginning of the 6th century. He is said to have built one of the oldest churches in Rome, Santa Pudenziana.
St Pius I endured many hardships during his reign. The fact that Saint Justin taught Christian doctrine in Rome during the pontificate of St Pius I and that the heretics Valentinus, Cerdon, and Marcion visited Rome at the same time, is an argument for the primacy of the Roman See during the 2nd century. Pope Pius I opposed the Valentinians and Gnostics under Marcion, whom he excommunicated.
