Jerald and Sandra Tanner's overview of Adam-God; concludes that, while Brigham Young did teach Adam is God, the modern LDS Church does not hold it to be a doctrine.

In all fairness to the Mormon Church it should be stated that they no longer teach the Adam-God doctrine, even though some members of the church still believe it. Anyone who is caught teaching this doctrine is liable to be excommunicated. This, however, shows the inconsistency of the Mormon Church, for they say that Brigham Young was a prophet, and at the same time they will excommunicate a person for believing in his teachings.
