Interestingly, the host of Mormon stories, a fantastic you tube channel, says he was approached by Prior to be an expert on the LDS church.
He has deeply covered how going "deep" into the theology does logically lead to off shoots like Chad's. Even though "headquarters" does not teach it to the general churchgoer. Off shoots think the church has liberalized to apostasy. The church when pushed says the cults are apostasy. And leaders might get excommunicated for claiming to be s prophet.
When push comes to shove, reading deep and studying what does not get taught in the church, LDS literature supports the off shoots, even if "headquarters" does not.
That's why there are conflicting emotional responses to cases like this. "That's not real LDS," competes with "The LDS church is a cult itself and caused it."
What I have learned is, they are both right! I get the impression most Mormons never learn know or care about the "extreme" teaches embedded in scripture, but not encourage by the church.
It's not a matter of interpretation, either. Like"Spate the rod and spoil the child," which justifies or forbids beating children, depending on how you read it.
Books like "The second Comforter," a cult favorite, spend a lot of ink saying, "they didn't tell you this, but...."
BTW, a lot of this stuff also is ancient. Such as possession. Jesus apparently did castings. But personally being a prophet gives the church pain, but their own scriptures back it up.
So things could get interesting if Chad's defense is, this is no cult, this is mainstream!
MOO
