d.268. Bishop of Caesarea in Cappadocia from about 230. A great admirer of Origen, they exchanged visits and he was able to study under him. Firmilian was clearly a man of great influence in the East, but his only surviving work is a letter to Cyprian (Cypr., Ep.75). In this he supports Cyprian's contention that baptism belongs to the church alone and is therefore invalid outside its confines. He rejects the opposing view of Stephen, bishop of Rome, with all the considerable power of scorn at his command. He presided over at least one synod to deal with the heretical Paul of Samosata, bishop of Antioch, in 264, and died at Tarsus on his way to Antioch to a further synod to decide this issue.
