My most recent post on M* is Mormons as Modalists. Here is a preview:
An interesting fact of Divine Investiture is that it makes Mormons “Modalists,” after a fashion.
Here I pause to the storm of disaffected Mormon and anti-Mormon protest. “No, Mormons aren’t Modalists! They are the opposite of Modalists! They are Freakin’ Tritheists!”
I also pause to let the Believing Mormons protest (assuming they’ve even heard of Modalism before). “No! I am not a Modalist! That’s… a heresy! It’s worse than… than… the Trinity Doctrine!”
