Fourth Century - The Nicean Creed

The Nicean Creed
One of the most important things accomplished at the Council of Nicea was the adoption of a creedal form that would guide the Church regarding theology, Christology, and the trinity. As has been mentioned, there was great debate about the use of the term homoousias. The creed did not have 100% approval even when it was drafted. Within a short amount of time the creed came under attack, and eventually was rewritten at the Council of Constantinople in 381 AD.

This is the text of the original version of the creed:

The Original Creed of 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 of the Father [the only-begotten; that is, of the essence of the Father, 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 [both in heaven and on earth];

Who for us men, and for our salvation, came down and was incarnate and was made man;

He suffered, and the third day he rose again, ascended into heaven;

From thence he shall come to judge the quick and the dead.

And in the Holy Ghost.

[But those who say: 'There was a time when he was not;' and 'He was not before he was made;' and 'He was made out of nothing,' or 'He is of another substance' or 'essence,' or 'The Son of God is created,' or 'changeable,' or 'alterable' - they are condemned by the holy catholic and apostolic Church.]

At the end of the original creed was added the text above - obviously aimed at Arius.
