Elijah
- The Old Testament prophet who, Latter-day Saints believe, returned as a resurrected messenger to restore the sealing keys that bind families for eternity.
Latter-day Saints believe Elijah appeared in the Kirtland Temple in 1836, fulfilling Malachi's prophecy that he would "turn the hearts of the fathers to the children." This is the doctrinal basis for temple sealing and family history work.
