Saint Pamphilus (; latter half of the 3rd century – February 16, 309 AD), was a presbyter of Caesarea and chief among the biblical scholars of his generation. He was the friend and teacher of Eusebius of Caesarea, who recorded details of his career in a three-book Vita that has been lost. Biography Eusebius' Martyrs of Palestine attests that Pamphilus was of a rich and honorable family of Beirut. This work also asserts that he gave all his property to the poor and attached himself to the "perfect men". Photius quotes Pamphilus's Apology for Origen to the effect that Pamphilus went to Alexandria, where his teacher was Pierius, the head of the famous catechetical school there, before settling in Caesarea Maritima, where he was ordained a priest. In Alexandria, Egypt, Pamphilus became devoted to the works of Origen of Alexandria. Photius says that Pamphilus was a Phoenician born at Berytus, and a scholar of Pierius, who collected sacred literature. According to Eusebius, he suffered martyrdom in the third year of the Diocletianic persecution, after spending two years in prison. While he was in prison, Pamphilus and Eusebius worked together on five books in defense of Origen. The Diocletianic persecution began in earnest in the year 303. In 306 a young man named Apphianus—a disciple of Pamphilus "while no one was aware; he even concealed it from us who were even in the same house"—interrupted the governor in the act of offering sacrifice, and paid for his boldness with martyrdom. His brother Aedesius, also a disciple of Pamphilus, suffered martyrdom about the same time at Alexandria under similar circumstances. Saint Pamphilus's turn came in November, 307. He was brought before Urbanus, the governor of Palestine, and upon refusing to offer sacrifice, was cruelly tortured, and then relegated to prison. In prison he continued copying and correcting manuscripts. He also composed, in collaboration with Eusebius, also imprisoned, an Apology for Origen in five books, which Eusebius edited and to which he added a sixth book. Saint Pamphilus and other members of his household, along with Valens, deacon of the Church of Jerusalem and Paul of Jamnia, men "in the full vigour of mind and body", were without further torture sentenced to be beheaded in February, 309. While sentence was being given a youth named Porphyrius - "the slave of Pamphilus", "the beloved disciple of Pamphilus", who "had been instructed in literature and
