I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed. Galatians 1:6-9
Not only one other "gospel", but two others as well - Doctrines and covenants and Pearl of great price (which includes the bogusly translated egyptian papyrus of a pagan burial prayer).

My wife/kids and I recently moved to Utah and I have read those verses over and over since we got here. Paul does an excellent job of summing up every other pseudo Christian religion out there.
