I had it explained to me by a fellow graduate student, who was LDS, that I couldn't be a "real" Christian because I had not accepted the "Restored" Gospel. That is a game that two sides play.
Jesus said I will build my church and the gates of hell will not prevail against it.
So this idea of the Mormons that the church got "lost" is directly opposed to what Christ said. We have the faith that was once delivered to the saints. It has come down to us from Christ Himself thru the preaching of the Apostles and countless disciples.
I don't know which part of the bible they think is true and which untrue or how they determine what to pick and what to toss out. Just a rudimentary look says that everything Paul preached is tossed, and no wonder, his words are their strongest condemnation.
That was a long time ago. Now you will just spend eternity in the cheap seats of Heaven.
