Category:First Council of Nicaea

The First Council of Nicaea (325) lasted two months and twelve days. Three hundred and eighteen bishops were present. Hosius, Bishop of Cordova, assisted as legate of Pope Sylvester. The Emperor Constantine was also present. To this council we owe The Creed (Symbolum) Of Nicaea, defining against Arius the true Divinity of the Son of God (homoousios), and the fixing of the date for keeping Easter (against the Quartodecimans).
