LDS is not part of Christianity.
In the interest of being tolerant and nice, we've let this nonsense claim persist for too long.
When you take elements of one religion and then pile up a bunch of contradicting novel elements on top of them, you've created something else.
Which is fine. But Mormons need to move on and stop the charade that they're part of Christendom.
Sure, one or two heretical claims wouldn't necessarily place it outside Christianity, but polygamy enthusiast Joseph Smith loaded up his sect with claims that God was once a man (and is married to a female goddess), Jesus and Satan are brothers, there are an infinite number of gods, there is no original sin, and that every historic Christian creed should be rejected.
And when you add stuff like the planet Kolob, baptizing the dead, special underwear, an ancient Israelite presence in the US (along with the "Egyptian" language and Jesus himself)... well, you get the idea.
Can anyone tell me why The Church of Jesus Christ of Latter-day Saints was left out of the list of Christian churches?
