Was he a fraud or a prophet?
Today I found myself reading a quote by Gordon B. Hinkley, President of the Church of Jesus Christ of Latter-day Saints. This is what he said, "We declare without equivocation that God the Father and His Son, the Lord Jesus Christ, appeared in person to the boy Joseph Smith... ... Our whole strength rests on the validity of that vision. It either occurred or it did not occur. If it did not, then this work is a fraud. If it did then it is the most important and wonderful work under the heavens." (President Gordon B. Hinkley, "The Marvelous Foundation of Our Faith," Ensign, Nov. 2002, 80.)
It doesn't get any more plain and simple than that.
