M: I never did consider the Book of Mormon to be authentic. At least I have no recollection of ever seriously believing in the Book of Mormon. No doubt when I was a child I did hold that belief, but I have no recollection of it. Frankly, I am always somewhat amused by those who make extensive studies of the Book of Mormon through archeological remains, computer word studies, etc., in their attempt to prove its authenticity or to come to some conclusions as to whether it is what it purports to be.
O: Are you saying that the story of Moroni bringing the Book of Mormon to Joseph is a fabrication?
M: I won't comment here on Joseph Smith and his claims because he was a remarkably complicated person, and we don't know enough about him to competently judge his motives and mentality. My point is that I came to the conclusion at a very early age, earlier than I can remember, that you don't get books from angels and translate them by miracles; it is just that simple. So I simply don't believe the Book of Mormon to be authentic. I think that all of the hassling over the authenticity of the Book of Mormon is just a waste of time. You should understand that I don't mean to say that there aren't some interesting and worthwhile things in the Book of Mormon. I really don't even mean to attack the Book of Mormon but rather to simply deny its authenticity. I don't believe that it is what the Church teaches it to be. I know of no real evidence in its support, and there is a great deal of evidence against it. As you no doubt know, B. H. Roberts set forth some of that evidence in an unpublished book-length study of the Book of Mormon.
O: Doesn't that mean then that in your opinion the Church is merely a facade?
M: Of course not. I think it is unfortunate that a church should ground itself so thoroughly on something that is, in my opinion, not genuine and obviously is seriously doubted by thousands of persons who are in the Church and love the Church. But the Church is not a book, nor is it a collection of books—the standard works. Nor is it simply an ecclesiastical organization. The Church is the people who constitute it and their relationships to one another, their hopes and aspirations, their mutual love, their joys and tragedies. Whatever one might say about the Church's scriptures, its ecclesiastical organization, or its theological or historical claims, the Church is certainly not a facade. It is a living, moving, religious community and should not be judged on any other terms than its character and quality — its capacity to bring satisfaction and happiness to the people, to give them the strength and courage to live through the dangers and tragedies of life.
