We believe in one God, the Father Almighty, the Creator of heaven and earth, of [things] visible and invisible.
And in one Lord Jesus Christ, the Son of God, the begotten of God the Father, Only-begotten, that is of the Essence of the Father. God of God, Light of Light, true God of true God, begotten and not creature; of the very same Nature of the Father, by Whom all things came into being in heavens and on earth, visible and invisible; Who for us men and for our salvation came down from Heaven, was incarnate, became man, was born perfectly of the saint virgin Mary by the Holy Spirit. By whom He took body, soul, and mind, and everything that is in man, truly and not in semblance. He suffered, was crucified, was buried, on the third day He rose again, He ascended into Heaven with the same body, [and] sat at the right [hand] of the Father. He is to come with the same body and with the Glory of the Father to judge the living and the dead; of His kingdom there is no end.
We believe also in the Holy Spirit, the uncreated and the perfect; Who spoke through the Law and through the Prophets and through the Gospel [Books]; Who came down upon the Jordan, preached through the Apostles and dwelled in the saints.
We believe also in only one Universal and Apostolic [holy] Church, in one baptism, in repentance, in the expiation and forgiveness of sins, in the resurrection of the dead, in the everlasting judgment of souls and bodies, in the Kingdom of Heaven, and in the life eternal.
