How early Mormon leader Joseph Fielding and other Mormons responded to the King Follett discourse (April 7, 1844):
“I never felt more delighted with his discourse than at this time. They said at his oration, it is the voice of a god not of a man.” (Journal of Joseph Fielding, quoted in “The King Follett Discourse: Joseph Smith’s Greatest Sermon in Historical Perspective”)
How the people of Tyre and Sidon responded to the oration of Herod:
“On an appointed day Herod put on his royal robes, took his seat upon the throne, and delivered an oration to them. And the people were shouting, ‘The voice of a god, and not of a man!’ Immediately an angel of the Lord struck him down, because he did not give God the glory, and he was eaten by worms and breathed his last.” (Acts 12:21-23)
Joseph Smith died 81 days later, June 27, 1844.
Idolatry never wins in the end. “But the word of God increased and multiplied.” (Acts 12:24)
Note: The LDS manual “Church History In The Fulness Of Times Student Manual” awkwardly makes favorable use of Acts 12:20-23 to describe how the saints were “profoundly moved” by the King Follett discourse.
