My son asked an excellent question one time about Mormons and Christianity:
So, if they believe you are only a Christian if you believe in the Nicene Creed, does that mean there were no Christians before 320 AD?
Excellent question. Mormons rely heavily on Biblical descriptions of Christ, and God, and are doing their best to re-establish the original Christian Church. If Peter, James, John, and Paul, Phillip, and the other apostles were Christians without the Nicene Creed, why can't Mormons be?
