I meant to post about this a long time ago but forgot. Anyway, if you saw the PBS special on the Mormons, you may have noticed a reference to one of the early LDS founders, Sidney Rigdon. Turns out, he started in the COC, along with Alexander Campbell, but grew disillusioned with AC and glommed onto Joseph Smith instead. For me, it's just further proof that the COC has more in common with the Mormons, the Jehovah's Witnesses, and other quasi-Christian sects that originated during the 19th century than it does with Christianity at large, since all those movements traded people back and forth for many years. Anyway, if you didn't get a chance to watch the Mormons special on PBS, you can watch it online. You should also read Under the Banner of Heaven for a riveting history of the Fundamentalist Latter Day Saints, the ones who still practice polygamy.
