The Church of Jesus Christ of Latter-day Saints considers itself the “restoration” of a complete Christianity that was lost centuries ago after the death of the biblical apostles.

Several years ago, Denver Snuffer, a former Latter-day Saint, launched his Remnant movement, preaching that the Utah-based faith fell away from the truth after founder Joseph Smith was killed in 1844 and Brigham Young led his followers West.

Now, yet another faction, called The Doctrine of Christ, has emerged. Phil Davis, a Latter-day Saint in Provo, asserts that Young murdered Smith and that Mormonism’s first prophet recently returned to re-restore the church with Davis at its helm.

On this week’s show, Cristina Rosetti, a religious studies scholar at Claremont McKenna College in Southern California, discusses these groups, why some Latter-day Saints are joining them, how conspiracy theories play a role, and whether they pose any threat to the mainstream church.
