An 8 November 1831 conference authorized JS to “correct those errors or mistakes” that he found in the revelations “by the holy Spirit.” This may have included reviewing and revising them according to his developing understanding of church doctrine and ecclesiology. Decades later William E. McLellin remembered that around November 1831, JS, Cowdery, and Rigdon spent hours revising the revelations. A 1 December 1832 entry in JS’s journal also states that he “wrote and corrected revelations” that day. McLellin wrote that the April 1832 assignment to Cowdery, Phelps, and Whitmer was to “better the language” of the revelations.
