Vaughn J. Featherstone calls "Adam-God" a "theory" and those who profess belief in it as ignorant of the basics of the Gospel.

Another case is the one of those who talk about the “Adam-God” theory; I guess when they are engrossed with all these different theories, and things in the Church, they don’t have time to study faith and repentance. Maybe they ought to get back to basics. And when they understand everything about faith, then they can move on to the next principle.
