(From the Council of Nicea in 325 AD)
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, begotten from the Father, only-begotten, that is, from the essence of the Father, God from God, light from light, true God from true God, begotten not made, of the same essence as the Father, through Whom all things came into being, things in heaven and things on earth, Who because of us men and because of our salvation came down, and became incarnate and became man, and suffered, and rose again on the third day, and ascended to the heavens, and will come to judge the living and dead,
And in the Holy Spirit.
But as for those who say, There was [a time] when He was not, and, Before being born He was not, and that He came into existence out of nothing, or who assert that the Son of God is of a different hypostasis or essence, or created, or is subject to alteration or change – these the Catholic and apostolic Church anathematizes.
