Why don't you all just settle down and do what the Apostle Paul did. Preach Christ crucified.
Yet they can all pretty much agree on the nature of God and Jesus, that the Bible is the Word of God.
Mormonism tears them down, makes them common men who gained godhood (were polygamists) and claims that Christianity was TOTALLY lost from the earth (in direct contravention to Christ’s own words) and that the Bible is mistranslated (yet cannot point to where).
That’s much more than a simple disagreement over something like communion or how to pray to God, etc.
The mormons aren’t a “Christian” denomination. Please do your homework. They are a cult. And you mentioned Catholics? Beck used to be one. They are the one true Church. He left it. And so it goes....
