Firmilian
3rd century Bishop of Caesarea Mazaca

Firmilian (Greek: Φιρμιλιανός, Latin: Firmilianus, died c. 269 AD), 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).
Life
Gregory of Nyssa tells that Gregory Thaumaturgus, when still a pagan, having completed his secular studies, "fell in with Firmilian, a Cappadocian of noble family, similar to himself in character and talent, as he showed in his subsequent life when he adorned the Church of Caesarea." The two young men came to Alexandria to study with Origen by whom Gregory, at least, was baptised. Firmilian was more probably brought up as a Christian.
Later, when bishop of Cæsarea in Cappadocia, according to Eusebius, Firmilian invited Origen to his own country for the benefit of the Churches, around (232-5) when Origen was staying in Cæsarea of Palestine, on account of his bishop's displeasure at his having been ordained priest in that city.
