"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 only-begotten Son of God, begotten of the Father before all ages. Light of Light, very God of very God, begotten, not made, of one essence with the Father, through whom all things were made. Who for us and for our salvation came down from heaven and was incarnate of the Holy Spirit and the Virgin Mary and became Man. He was crucified for us under Pontius Pilate, and suffered and was buried. On the third day He rose 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, and His kingdom will have no end. And I believe in the Holy Spirit, the Lord, the Giver of Life, who proceeds from the Father. Who with the Father and the Son together is worshiped and glorified, and who spoke by the prophets. And I believe in One, Holy, Catholic, and Apostolic Church. I acknowledge one baptism for the forgiveness of sins. I look for the resurrection of the dead, and the life of the world to come. Amen."
