The King Follett discourse, or King Follett sermon, was an address delivered in Nauvoo, Illinois by Joseph Smith, president and founder of the Latter Day Saint Movement, on April 7, 1844, less than three months before his assassination. The discourse was presented to a congregation of probably more than twenty thousand Latter-day Saints at a general conference held shortly after the funeral service of Elder King Follett, who had died on March 9, 1844, of accidental injuries. The sermon is notable for its claim that God was once a mortal man, and that mortal men and women can become gods (a concept commonly called divinization) through salvation and exaltation. These topics were, and are, controversial, and have received varying opinions and interpretations of what Smith meant. Literary critic Harold Bloom called the sermon "one of the truly remarkable sermons ever preached in America."
A full, verbatim account of the speech does not exist, but notes exist, taken contemporaneously, by Thomas Bullock (using a type of personal shorthand), William Clayton (writing in longhand), and Willard Richards (taking "minute"-style notes of major elements of the speech).Wilford Woodruff also took extensive contemporaneous notes and transferred the notes to his journal with editorializations, but his original notes were not preserved. One author (Searle) estimates that the surviving notes of the sermon contain roughly 30% of the words of the actual address, but that together, they are likely nearly topically complete.
