We believe in one God, the Father Almighty, maker of all things visible and invisible; and in one Lord Jesus Christ, the Son of God, the only-begotten of his Father, of the substance of the Father, God of God, Light of Light, very God of very God, begotten not made, being of one substance (homoousios) with the Father. By whom all things were made, both which is in heaven and in earth. Who for us men and for our salvation came down [from heaven] and was incarnate and was made man. He suffered and the third day he rose again, ascended into heaven. And he shall come again to judge both the living and the dead. And [we believe] in the Holy Ghost. And whosoever shall say that there was a time when the Son of God was not, or that before he was begotten he was not, or that he was made of things that were not, or that he is of a different substance or essence [from the Father] or that he is a creature, or subject to change or conversion--all that so say, the Catholic and Apostolic Church anathematizes them.
