Bishop Paul of Constantinople/Istanbul (d. AD 350)
Paul served as Constantinople’s bishop for 13 years, from 337 to 350. He opposed Arianism at Nicea’s Ecumenical Church Council in 325 and assisted in writing the first version of the Nicene Creed. However, Arianism continued to spread throughout the church of Asia Minor by the efforts of bishop Eusebius of Nicomedia, Constantius II, and Valens. Because Constantius II did not like Paul’s anti-Arian position, he expelled him and ordained Arian Eusebius of Nicomedia as Constantinople’s new bishop in 338. In 350, some Arians strangled Paul to death while he was celebrating a public worship service.
