He was later elected bishop of Harran in Mesopotamia (Carrhae), where he worked vigorously to reduce the existing abuses. He died in Constantinople in 422 after going there to consult with Theodosius II, although some argue that it may have instead occurred in 390 under Theodosius II's predecessor, Theodosius I. His body was transferred back to Harran, to the city of Antioch where he was buried. His feast day is 14 February.
