Pius I

Saint Pius I was born in Aquileia in northern Italy toward the end of the first century, the son of Rufinus. Ancient tradition also links him to Hermas, author of The Shepherd of Hermas, suggesting a family marked by humble origins and deep faith. In the mid–second century, during the reigns of the emperors Antoninus Pius and Marcus Aurelius, Pius was chosen as Bishop of Rome and served as the ninth successor of Saint Peter. His pontificate was a time of doctrinal testing, as influential teachers such as Valentinus, Cerdon, and Marcion came to Rome. Pius is remembered for defending the Church against Gnostic errors and for safeguarding the unity of apostolic teaching, even to the point of excommunication when necessary. Tradition also credits him with fostering the Church’s worship and life in Rome, including an early connection to the venerable church of Santa Pudenziana, and with insisting that Easter be celebrated on a Sunday. He is venerated as a saint and is patron of Roccaspinalveti, San Pio delle Camere, and Valgioie. His feast day is July 11.
