Jim Jessop, son of FLDS Bishop Merril Jessop, goes through the morning routine with his children and three wives (names to come) on the YFZ Ranch. The family usually wake up around 5am, get dressed, have a family reading and prayer, and then have breakfast together. The Fundamentalist Church of Jesus Christ of Latter Day Saints is one of the largest Mormon fundamentalist denominations and one of United States' largest practitioners of plural marriage. The FLDS Church emerged in the early 1900s when its founding members left The Church of Jesus Christ of Latter-day Saints. The split occurred largely because of the LDS Church's renunciation of polygamy and its decision to excommunicate practitioners of plural marriage.
