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.
