Hieromartyr Pamphilus of Caesarea, Presbyter

IMPORTANT DATE CORRECTION: the previously listed date "June 16" was not confirmed by any source; the correct date, consistently confirmed by all sources (drevo-info.ru, azbyka.ru, Wikipedia), is February 16 (matching the standard 13-day O.S./N.S. offset with March 1).

Hieromartyr Pamphilus was born around 240 in Berytus (modern Beirut) to a wealthy family, receiving a classical and theological education there and in Alexandria, where he studied under the presbyter Pierius, an heir to the Origenist tradition. He was ordained presbyter at Caesarea Maritima, where he devoted his considerable wealth and learning to the Church — founding a theological school and assembling a library of Christian and secular texts numbering around 30,000 volumes, one of the great libraries of the ancient Christian world, later used by Blessed Jerome and Eusebius. He personally copied and collated manuscripts of Scripture, and worked with Eusebius to compare the text of the Septuagint against the Hebrew original. Eusebius of Caesarea was his close friend, student, and collaborator, and out of veneration adopted the additional name "Eusebius Pamphili."

During the persecution of Maximinus Daia (a continuation of Diocletian's edicts), Pamphilus was arrested in 307, tortured, and imprisoned for about two years, during which he continued theological work (including, with Eusebius, a defense of Origen). He was executed by beheading on February 16, 309, together with a group of fellow confessors — the deacon Valens, the layman Paul, and others — bringing the total number of martyrs who suffered with him to twelve.

His feast is kept on February 16/March 1.
