Polycarp, bishop of Smyrna, one of the early Fathers of the Church, a disciple of the Apostles and in particular of St. John; was for nearly 70 years bishop, and suffered martyrdom for refusing to renounce Christ, "after having served Him," as he said, "for 86 years"; of his writings the only one extant is an "Epistle to the Philippians," the genuineness of which, at one time questioned, is now established, and is of value chiefly in questions affecting the canon of Scripture and the origin of the Church.
