The first ecumenical synod was held at Nicaea in A.D. 325, which decided to state the Christian faith in words, that it would clear the doubts about what is the true faith. The synod formulated the fundamental beliefs of all Christians in what has since been known as the ‘Nicene Creed’. The second and third synods at Constantinople and Ephesus expanded this statement of faith to counter various heresies (heterodoxies). To this day, this remains the creed of the Orthodox Church.
We believe in one true God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.
And in one Lord, Jesus Christ, the only-begotten Son of God, Who was begotten of the Father before all worlds; light of light, true God of true God; begotten and not made; and being of one substance with His Father, by Whom all things were made; Who for us men and for our salvation came down from heaven and was incarnate by the Holy Spirit and of the Virgin Mary, Mother of God. And He became man, and was crucified for us in the days of Pontius Pilate, and He suffered, died and was buried, and the third day He rose according to His will, and ascended into heaven, and sits at the right hand of His Father; and He will come again with great glory to judge both the living and the dead; and His kingdom shall have no end.
And we believe in the Holy Spirit, the Lord, the Giver of life to all, Who proceeds from the Father; Who together with the Father and Son is worshipped and glorified, Who spoke through the Prophets and Apostles.
And in one, holy, catholic, and apostolic Church. We confess one baptism for the remission of sins. And we look for the resurrection of the dead, and the new life in the world to come.
