Looks like TheChristian summed up things nicely with his post following yours about how faith heals.
There is nothing I could disagree with more than your above statement. There is no way God gave his stamp of approval on everything this church has taught. It is a ridiculous thought. God always allows the growth that comes from learning on our own that certain doctrines are wrong. He was not the originator of the priesthood ban, but he allowed it so that we could eventually learn to stand against it. If we have nothing but truth in the church, we never get tested and turn into thoughtless drones.
