The First Council of Constantinople (Latin: Concilium Constantinopolitanum; Ancient Greek: Σύνοδος τῆς Κωνσταντινουπόλεως) was a council of Christian bishops convened in Constantinople (now Istanbul, Turkey) in AD 381 by the Roman Emperor Theodosius I.^[1]^[2] This second ecumenical council, an effort to attain consensus in the church through an assembly representing all of Christendom, except for the Western Church,^[3] confirmed the Nicene Creed, expanding the doctrine thereof to produce the Niceno-Constantinopolitan Creed, and dealt with sundry other matters. It met from May to July 381^[4] in the Church of Hagia Irene and was affirmed as ecumenical in 451 at the Council of Chalcedon.
