The Nicene Creed

First Council of Nicaea

The First Council of Nicaea, convened by the Emperor Constantine in A.D. 325, was the first ecumenical council of the Church. Some three hundred bishops assembled to answer the teaching of Arius, who held that the Son was a creature and not truly God. Against him the council confessed the Son to be homoousios — of one essence with the Father — and set forth the Creed that stands as the foundation of all later confessions of the faith.

1. 1. The Symbol of Faith

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 (γεννηθέντα), not made, being of one substance (ὁμοούσιον, consubstantialem) with the Father. By whom all things were made, both which be 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, and ascended into heaven. And he shall come again to judge both the quick 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 (ἤν ποτε ὅτε οὐκ ἦν), 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 [τρεπτὸν in Greek; convertibilem in Latin] — all that so say, the Catholic and Apostolic Church anathematizes them.
