Per Atrios, I can’t shed many tears for Mitt Romney when people start highlighting some of the more unusual aspects of Mormon theology. I don’t think you get to say: “It’s vital, and crucially relevant to my qualifications for office, that I have a powerful set of guiding convictions… but never mind the actual contents of those beliefs.”
That said, now that I’ve read the account of the doctrine that Jesus is Satan’s older brother, I kind of like it. If Jesus is just sort of constitutionally perfect and sinless, it seems less impressive, in a way. If he could have been another Satan but opted to go the messiah route, that’s another story again. Though even in the latter case, I suppose watching dad throw your little brother into a lake of fire will tend to strengthen your disposition toward filial deference.
