BTW, they are walking this whole “small-g god was once a man” business back now a bit because of the reaction that it gets among non-Mormons.
For much of rest of the Christian world, although theology itself can develop, the deposit of faith is “set in stone” and unchangeable as part of revelation which is now closed. This is especially true for Catholics and Orthodox. However, it’s not at all true for Mormons.
Revelation is not closed according to the Mormon church and the “essentials” of what is commonly believed by members of the Mormon church can shift and have several times. It’s really all very fluid.
PS. I have a Mormon uncle and Mormon co-workers with whom I have discussed this many times.
PS. My comments are not to be construed as prejudiced against the religious freedom of Mormons to be Mormons. I am simply stating facts about comparative theology. It’s important that people understand the different belief systems so that they can avoid superficial ideas about these important matters.
