Doctrine of the Orthodox Church

The Nicene Creed

I believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible; And in one Lord Jesus Christ, the Son of God, the Only-Begotten, begotten of the Father before all worlds, Light of Light, Very God of Very God, begotten, not made; of one essence with the Father; by Whom all things were made: Who for us men and for our salvation came down from heaven and was incarnate of the Holy Spirit and the Virgin Mary, and was made man; And was crucified also for us under Pontius Pilate, and suffered and was buried; The third day He arose again, according to the Scriptures; And ascended into heaven, and sits at the right hand of the Father; And He shall come again with glory to judge the living and the dead; Whose Kingdom shall have no end. And I believe in the Holy Spirit, the Lord and Giver of Life, Who proceeds from the Father; Who with the Father and the Son together is worshipped and glorified, Who spoke by the prophets. And I believe in One Holy, Catholic, and Apostolic Church. I acknowledge one Baptism for the remission of sin. I look for the Resurrection of the dead and the life of the world to come. Amen.
