The Pure Church of Christ is the first known schismatic organization to emerge from the Latter Day Saint movement.
According to George A. Smith, Wyman Clark was baptized about the same time as Sidney Rigdon. He, another follower of Joseph Smith, Jr. named Northrop Sweet and four unnamed others were responsible for the creation of the “Pure Church of Chris” At the time of the creation of the “Pure Church of Christ” in Kirtland, a society that had undertaken to have a community of property. A number of people located on a farm owned by Isaac Morley had been baptized, but had not yet been instructed in relation to their duties. These people claimed that a spirit entered into them. Some clamed to see angels, and letters would come down from heaven.
Upon hearing of these “Event” Joseph Smith, Jr. came to Kirtland, in order to teach these Saints that they were in error. When Joseph attempted to instruct these Saints in relation to the true Spirit, and the manner of determining the one from the other, in a short time a number of those who had been influenced by those manifestations, apostatized. Among the number was Wycom Clark who claimed he received a revelation that he was to be the prophet and that he was the true revelator. Clark organized the "Pure Church of Christ," and commenced having meetings, and preaching.
