Early Mormon teaching was that Jesus and Lucifer were brothers. Lucifer’s plan for redeeming the human race was rejected by Elohim, the head of the council of gods. Jesus’ plan was accepted. I don’t know whether the LDS church still teaches this, however.
While I don’t think Romney being a Mormon is a issue, it is a church teaching. Regardless it does not serve Huckleberry hound well in bringing it up. Mormons can believe what ever they want to...geez
Is anyone saying they can't believe what they want to? I don't think so.
But let me ask you this: is it somehow wrong to bring their beliefs to light? Or is Huckabee supposed to help the Mormons keep their deep-dark secret beliefs without anyone else finding out about them?
