Mom, to be fair, the LDS church has never officially adopted the "Adam is God" doctrine. I think that most LDS members were as shocked by Brigham Young's statements about it as anyone would have been. It is not taught now and it was not taught 35 years ago, when I was still a member. For purposes of these discussions (specifically the reaction to the above sermon) the Adam/god doctrine is a diversion. I'd like to see this thing stay on topic, or else it will deteriorate into a "he said-she said" shouting match.
Lets all stick to the issue at hand. What does the Bible have to say about whether or not there is a plurality of Gods? What does the bible say about the nature of our God. Was he once a man before he became God?
