ABSTRACT
Christians confess God as Father, Son and Holy Spirit. The classical statement of belief in the Triune God was adopted at the Council of Nicaea in 325 CE and reaffirmed and expanded at the Council of Constantinople in 381 CE. This creed, with its tripartite structure (‘We believe in one God the Father Almighty, maker of heaven and earth … and in one Lord Jesus Christ, the only son of God, begotten of the Father before all worlds … and in the Holy Spirit the Lord and Lifegiver’), is used to this day by millions of Christians throughout the world when they celebrate the Eucharist. It is the most ancient authoritative summary of Christian teaching and the mark of orthodox Christian faith.
