Evangelical Inquirer (March 1831) publishes David S. Burnett's description of Moroni as a "ghost."
David S. Burnett, “Something New—‘The Golden Bible,’” Evangelical Inquirer [Dayton, Ohio], March 7, 1831, 218-219
The ignorance and superstition of these fanatics soon conjured up a ghost, who they said was often seen and to whom was committed the care of the precious deposit. This tradition made money diggers of many who had neither intelligence nor industry sufficient to obtain a more reputable livelihood. But they did not succeed and as the money was not dug up, something must be dug up to make money. The plan was laid, doubtless, by some person behind the curtain, who selected suitable tools. One Joseph Smith, a perfect ignoramus, is to be a great prophet of the Lord, the fabled ghost the angel of his presence, a few of the accomplices the apostles or witnesses of the imposition, and, to fill up the measure of their wickedness and the absurdity of their proceedings, the hidden golden treasure, is to be a golden bible and a new revelation. This golden bible consisted of metallic plates six or seven inches square, of the thickness of tin and resembling gold, the surface of which was covered with hieroglyphic characters, unintelligible to Smith, the finder, who could not read English. However the angel (ghost!) that discovered the plates to him, likewise informed him that he would be inspired to translate the inscriptions without looking at the plates, while an amanuensis would record his infallible reading; all which was accordingly done.
