Who they were
Firmilian, of a noble Cappadocian family, was a friend of St Gregory the Wonderworker and a disciple of Origen. As Bishop of Caesarea in Cappadocia he had a reputation comparable to that of St Cyprian.
He opposed the antipope Novatian, and in the baptismal controversy sided with St Cyprian. He died about 269.
