And in one Lord Jesus Christ, the only begotten Son of God, and born of the Father before all ages. (God of God) light of light, true God of true God. Begotten not made, consubstantial to 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 Ghost and of the Virgin Mary and was made man; was crucified also for us under Pontius Pilate, suffered and was buried; and the third day rose again according to the Scriptures. And ascended into heaven, sits at the right hand of the Father, and shall come again with glory to judge the living and the dead, of whose Kingdom there shall be no end. And (I believe) in the Holy Ghost, the Lord and Giver of life, who proceeds from the Father (and the Son), who together with the Father and the Son is to be adored and glorified, who spoke by the Prophets. And one holy, catholic, and apostolic Church. We confess (I confess) one baptism for the remission of sins. And we look for (I look for) the resurrection of the dead and the life of the world to come. Amen."
