Unlike other purely religious organizations formed by Joseph Smith, members of the Council of Fifty were not necessarily Latter Day Saints. At its formation, there were three non-Mormon members: Marenus G. Eaton, who had revealed a conspiracy against Smith by Nauvoo dissenters; Edward Bonney, whose brother was a Mormon but who later acted as prosecutor against Smith for his role in the destruction of the "Nauvoo Expositor"; and Uriah Brown. Their admittance reflected Mormon teachings that the Millennial theocracy would be multi-denominational, though Jesus himself would be king. Although Brigham Young did not admit non-Mormons to the Council during his administration, he invited both Mormons and non-Mormons to be part of the theocracy, and even part of the theocratic government. All three nonmembers would be expelled in early 1845 once Brigham Young became chairman of the council.
