The First Council of Constantinople (Latin: Concilium Constantinopolitanum; ‹See Tfd›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.
