Just remember who you're defending. The Mormon story goes something like this. When Joseph Smith turned 18 he prayed asking God which Church should he join. Catholics, baptists, protestants, lutherans, presbytarians, etc???? God answered. He said don't join any of them. They have all lost their authority from god during the dark ages. Corrupt popes. The connection between your church and God has been lost.
So God did a do over. He visited Joseph Smith in 1820 and told him to start a new church. So Mormon's do not think you traditional Christians are going to heaven. You're following a false religion. Lies. That bible of yours has been heavily edited and altered by the Catholic Church, who is all pedophiles.
