This phrase was used in the East to describe the relation of Christ to the Father within the Godhead. It was intended to clarify the nature of the Trinity and to reject Arianism. It was the term used to settle controversy over the place of Jesus Christ in the Trinity at the Council of Nicea I (325). Its use was confirmed by the Council of Constantinople I (381). Some theologians preferred the use of the term homoiousios (Greek for "of like substance") in order to emphasize distinctions among the three persons in the Godhead, but the term homoousios became a consistent mark of Nicene orthodoxy in both East and West.
