Presented here for the first time in English translation (from Rufinus's Latin version) is the Apology for Origen, the sole surviving work of St. Pamphilus of Caesarea (d. 310 AD), who was one of the most celebrated priest-martyrs of the ancient Church. Written from prison with the collaboration of Eusebius (later to become the bishop of Caesarea), the Apology attempts to refute accusations made against Origen, defending his views with passages quoted from his own works. Pamphilus aims to show Origen's fidelity to the apostolic proclamation, citing excerpts that demonstrate Origen's orthodoxy and his vehement repudiation of heresy. He then takes up a series of specific accusations raised against Origen's doctrine, quoting passages from Origen's writings that confute charges raised against his Christology. Some excerpts demonstrate that Origen did not deny the history of the biblical narratives; others clarify Origen's doctrine of souls and aspects of his eschatology. Pamphilus was beheaded on February 16, 310, under the emperor Maximinus Daia.
