Under the Banner of Heaven: A Story of Violent Faith is a nonfiction book by Jon Krakauer that was recently adapted and released as a limited streaming series on Hulu. In the book and TV series, two stories are examined: the origin and evolution of the Church of Jesus Christ of Latter-day Saints (LDS Church) and a modern double murder committed in the name of God by brothers Ron and Dan Lafferty, who subscribed to a fundamentalist version of Mormonism.

In the years prior to the murder, Ron and Dan Lafferty became increasingly interested in Mormon groups that accepted many beliefs of the original LDS church, including polygamy and direct communication with God.

Ron and Dan were charged for the throat-slashing homicides of their sister-in-law Brenda Wright Lafferty and her 15-month-old daughter, Erica, that occurred on July 24, 1984. Ron, a self-proclaimed prophet, claimed to have received a revelation from God in which he was instructed to "remove" several people, including the two victims.

Every church, every denomination and every religious group has its own broken past, scars and ugliness, but is the LDS church just like any other Christian denomination? Speaking of which, are Mormons just other Christians that happen to have a different form of practice and worship, like Baptists, Methodists, or Presbyterians? Or was the church actually founded on something completely different than Biblical Christianity?
