The Nicene Creed was not created by Christians, but by Constantine who was an avowed Pagan who wanted to unify the masses and keep them under subjection. It, along with other "creeds of men" was rejected by God and have been the cause of most of the problems with the lack of unity in the churches today. God told Joseph Smith that they were an abomination before him and that the truth would be shown unto Joseph later. The biggest truth that it missed was the Manhood, the Fatherhood and the Godhood of God himself and that he and his Son are two separate beings, thus the reason they both showed up in regards to Joseph's prayer, the vision that started the restoration of all things and the putting down of the false creeds of man.
