Blood Atonement

Blood atonement was a practice in the history of Mormonism still adhered to by some fundamentalist splinter groups, under which the atonement of Jesus does not redeem an eternal sin. To atone for an eternal sin, the sinner should be killed in a way that allows their blood to be shed upon the ground as a sacrificial offering, so they do not become a son of perdition. The largest Mormon denomination, the Church of Jesus Christ of Latter-day Saints, has denied the validity of the doctrine since 1889 with early church leaders referring to it as a "fiction" and later church leaders referring to it as a "theoretical principle" that had never been implemented in the LDS Church.
