When I was at Laughlin AFB, in Del Rio by golly Texas, I met one of the supposedly best authorities on Mormonism. He was a retired USAF E-9. It was his opinion that ole Joe Smith was a teller of tall tales, and concocted this whole Book of Mormon thing, as just a story, with the hope of selling it, to make money, and it got away from him and a new religion began. If that is true, and it may very well be, I would say that is a classic example of people having itching ears. If this doctrine did not come from God, then I have an idea where it DID come from.
