In the Nicene Creed, the Lord Jesus Christ is no longer "one in being with the Father." He is now " consubstantial with the Father." This too is thought to go back to the original better.
As long as they are trying to get back to originals, I think that it would be fun to go back to the original ending to the creed that the Council of Nicea came up with in 325 A.D.:
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.Apparently this was never very popular as it was dropped from the creed by the Council of Constantinople in 381 A.D.
