So, you believe the “demon” theory, too? Really. Aren’t you even a little embarrassed by it?
I know not exactly what guided Joseph Smiths hand, it may have been the Devil himself or could be as simple as that which drove PT Barnum to pursue his circus, a sucker is born every minute.
What I do know is what ever guided him did not come from above. God doesn't talk in circles, make hard right and left turns in his actions, ask us to lie, intentionally complicate salvation or waste his efforts on our behalf. Most of all he does not hide from his people only to randomly reappear in New York forest.
So if it is not from bellow or from the mind of man, there are precious few choices left...
