Some (though not all) members of these groups consider the term "Campbellite" derogatory, saying that they are followers of Jesus, not Campbell. They draw parallels with Martin Luther's protest of the name "Lutherans." Others deem it a neutral tribute to the origins of their churches in the work of Thomas Campbell and Alexander Campbell (among others). These groups were originally called "reformed Baptist", but were not related to the Reformed Baptist tradition.
Other prominent individuals in the early movement included Sidney Rigdon and Parley P. Pratt, who, along with more than 3,000 of their adherents converted to Mormonism in the 1830s in Ohio.
