That's bad, but the bigger theological problem (IMO) is the believe in "eternal progression". Since the LDS "Heavenly Father" was once a man, he is not God at all, as Christians, Jews, and Muslims would define the term. All three of those monotheistic faiths would insist that God is uncreated and eternally existent, absolute Being, whose existence neither depends nor has depended on anything else. The LDS "Heavenly Father" no more meets that definition than I do.
I only have one comment....... PING!
