It is of importance to understand the controversies of christology in regard of its parallel with the organisation of the church, as these are ideally united as one, the latter seen as the body of Christ. The issue of how to reconcile the claims of monotheism with the assertion of the divinity of Jesus of Nazareth was largely settled at the First Ecumenical Council held at Nicaea (325). Especially among the Greek-speaking Christians, attention turned to how to understand how the second person of the Trinity became incarnate in the person of Jesus Christ.[2] The Nicene Creed said of Jesus that he was "of one Being (ousia) with (God) the Father" and that he "was incarnate of the Holy Spirit and the Virgin Mary and became truly human."[3] However, neither the Nicene Creed nor the canons of the Council provided a detailed explanation of how God became human in the person of Jesus, leaving the door open for speculation.
