10. Elders Rigdon and Pratt fulfilled the mission appointed to them by this revelation. In company with Leman Copley, who at his own earnest request had been ordained to the Priesthood, (John Whitmer's _History of the Church_, p. 20) they visited the settlement of the Shakers, near Cleveland, Ohio, and preached the Gospel to them; "but," writes Elder Pratt, "they utterly refused to hear or obey the Gospel."--_Autobiography of Parley P. Pratt_, p. 65 (first ed.) John Whitmer also remarks upon this incident: "The above-named brethren went and proclaimed [the Gospel] according to the revelation given them, but the Shakers hearkened not to their words and received not the Gospel at that time, for they are bound in tradition and priestcraft; and thus they are led away with foolish and vain imaginations."--John Whitmer's _History of the Church_. Ms. p. 20. 11. This is a very brief allusion to very important and strange phenomena. Elder Parley P. Pratt, in his _Autobiography_, has a much more extended account of the spirit manifestations which called forth the revelation upon the subject. "As I went forth among the different branches," he says, alluding to the branches in the vicinity of Kirtland, "some very strange spiritual operations were manifested, which were disgusting rather than edifying. Some persons would seem to swoon away and make unseemly gestures, and be drawn or disfigured in their countenances. Others would fall into ecstasies and be drawn into contortions, cramp, fits etc. Others would seem to have visions, and revelations, which were not edifying and which were not congenial to the doctrine and spirit of the Gospel. In short, a false and lying spirit seemed to be creeping into the Church. All these things were new and strange to me and had originated in the Church during our absence, and previous to the arrival of President Joseph Smith from New York. Feeling our weakness and inexperience, and lest we should err in judgment concerning these spiritual phenomena, myself, John Murdock, and several other Elders, went to Joseph smith and asked him to inquire of the Lord concerning these spirits or manifestations. After we had joined in prayer in his translating room, he dictated in our presence the following revelation." This is the revelation given in the text above on spiritual manifestations. 12.
