Telesphorus was a second-century bishop of Rome, traditionally recognized as the eighth successor to Saint Peter. Born in Thurii, Italy, to Greek parents, he is said to have lived as a hermit before his election to the papacy. His leadership occurred during the reigns of emperors Hadrian and Antoninus Pius. He is remembered for his efforts to combat Gnosticism and for his role in maintaining Sunday celebrations of Easter, even while remaining in communion with diverse Christian communities.
