Professor J. B. Turner, of Illinois College, Jacksonville, Illinois, in his "Mormonism in All Ages" (1842), takes practically the same position, but goes a step further and undertakes to explain how the Prophet "deceived" the Witnesses, or how he "persuaded" them to believe, "in some sense," that they had actually beheld "the wonderful plates." In doing this the professor quotes the revelation given through the Prophet, in June, 1829, to Oliver Cowdery, David Whitmer, and Martin Harris, previous to their viewing the Nephite plates. [13] Also the revelation to Martin Harris in which he is promised that he shall be a witness to the truth of the Book of Mormon. [14] In the revelations cited the Lord promises these men that they shall view the Nephite record; and directs what they shall say after they have seen and heard the things promised. Because some of the phraseology of these revelations is found also in the testimony of the Three Witnesses, the professor rushes to the conclusion that the Witnesses never really saw the vision, nor heard the voice of God as promised, but were persuaded to accept these revelations through Joseph Smith as their witness to the truth of the Book of Mormon. In other words Professor Turner's theory is that the Witnesses had no other evidence than the word of Joseph Smith for the existence of the plates and other sacred things connected with them! And he triumphantly exclaims: Here, then, is the mighty power of God, the angel, and voice of the Lord, which revealed such marvels in 1830, all concentrated in the person, and pouring from the mouth of the Lord's Prophet in 1829. * * * * The whole, then, of this mighty array of bombast, nonsense, and blasphemy, resolves itself into this: "Joe Smith is not only 'author and proprietor' of the Book of Mormon, as both he and his Witnesses declare, but he is also 'power of god,' 'angel,' 'voice,' 'faith,' 'eyes,' 'ears,' and 'hands' for the Witnesses themselves; that is, all the evidence the world has for the Book of Mormon, after all this bluster, is 'Joe Smith's say so.' He says that God instructs him, he instructs the Witnesses and the Witnesses instruct the world. _Quod erat demonstradum_!" (p. 179.)
