The Nicene Creed 325 AD and updated in 381 AD
It was first written in 325 AD in Nicea (now Turkey) with 318 church fathers in attendance. As the heresies of the century continued they felt it was important to also address the divinity of the Holy Spirit and pronounced anathema upon those who taught against the full Triune God. The updated version was written in 381 AD.
Common in fourth century heretical teachings included rejections of Jesus Christ being a member of the Godhead and continued on with the same attack against the Holy Spirit with the Pneumatomachian teachings.
I believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.
And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds; God of God, Light of Light, very God of very God; begotten, not made, being of one substance with the Father, by whom all things were made.
Who, for us men for our salvation, came down from heaven, and was incarnate by the Holy Spirit of the virgin Mary, and was made man; and was crucified also for us under Pontius Pilate; He suffered and was buried; and the third day He rose again, according to the Scriptures; and ascended into heaven, and sits on the right hand of the Father; and He shall come again, with glory, to judge the quick and the dead; whose kingdom shall have no end.
And I believe in the Holy Ghost, the Lord and Giver of Life; who proceeds from the Father and the Son; who with the Father and the Son together is worshipped and glorified; who spoke by the prophets.
And I believe one holy catholic and apostolic Church. I acknowledge one baptism for the remission of sins; and I look for the resurrection of the dead, and the life of the world to come. Amen.
Also note: when the word “catholic” is used it’s not in reference to the Roman Catholic Church. The word “catholic” means universal and was used in this genre as referring to the whole body of Christ.
