What do you see as the basic differences between Mormonism/LDS and "mainstream" Protestant denominations (e.g., Baptist)? I am not interested in claims of moral superiority or authenticity, but rather basic beliefs in the relationship between Man and God.
A Mormon told me that when Jesus passed his authority on to his disciples and eventually was it Paul who was the first pope or Peter? Anyways, from that pope to the modern day pope, for centuries the Chistian/Catholic Church was corrupted and the whole thing is a scam.
So god told Joseph Smith to start his own religion, and that authority went from Joseph Smith to the Modern day leader of the Mormon church. The authority has never been broken. So all traditional christians are wrong.
The other ones I love are the born agains who say Christians who were baptized as babies need to be born again as adults otherwise we aren't saved and won't go to heaven. Nice angle to win over other Christians to your particular sect/cult of Christianity.
