after herbert armstrong's death in 1986, leaders in the wcg began to change the teachings of the church. this started in 1994. they changed the teachings to be more like other christian churches. many of the members wished to keep the original teachings, which they believed were the same beliefs as the early church of the first century. because of this, they left to start their own churches. ucg was established in may 1995 and is the largest church to come out of the wcg.
