Students of Mormon history may be familiar with the term “Campbellite” because Parley P. Pratt suggested that the first missionaries heading west in 1830 to preach the gospel to the Lamanites stop in Mentor, Ohio, to see his friend Sidney Rigdon, his former Campbellite minister prior to his conversion to Mormonism. Perhaps some know of the angry interactions in Hiram, Ohio, between the “Campbellites” and “Mormonites,” as they were pejoratively called at the time, or Alexander Campbell’s published essay on the Book of Mormon, his main title “Delusions” proclaiming his point of view. Many of the new converts to Mormonism in the Ohio region were previously reformed Baptists, Campbell's affiliation until about 1830. This competition for seekers of truth led to conflicts between the two groups.
