3rd AD century Bishop of Caesarea Mazaca
Firmilian, Bishop of Caesarea Mazaca from c. 232, was a disciple of Origen. He had a contemporary reputation comparable to that of Dionysius of Alexandria or Cyprian, bishop of Carthage. He took an active part in the mid-3rd century controversies over rebaptising heretics and readmitting lapsed Christians after the persecutions of Decius and was excommunicated by Pope Stephen I for his position. A single letter of Firmilian to Cyprian survives among Cyprian's correspondence. Jerome omits Firmilian from De viris illustribus. "To his contemporaries his forty years of influential episcopate, his friendship with Origen and Dionysius, the appeal to him of Cyprian, and his censure of Stephanus might well make him seem the most conspicuous figure of his time" (Wace).
