When I first ran into some kids who were Mormons, I immediately thought about them and what God said about Mormonism. I didn’t look into it all that much that day, but that night, I was reading my Bible and came across a verse that has never left my mind since: Galatians 1:8. Here is what it says:
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.
I’ve heard many accounts of who Joseph Smith saw when he prayed, but there is no doubt in the stories that the Angel Moroni came to Joseph and gave him the tablets on which were written the Book of Mormon.
I was very interested in this Angel Moroni because, according to the beliefs of the Mormons and the beliefs of Christians, there are obviously differences to significant to be called minor. Some of these have been documented HERE.
