What are the motifs in No Man Knows My History: The Life of Joseph Smith by Fawn M. Brodie?

American religion is a recurring idea in the book. No Man Knows My History, the Life of Joseph Smith, by Fawn M. Brodie, tells the story of the only successful American church. Joseph Smith formed a church, The Church of Jesus Christ of Latter-day Saints, which has lasted over 175 years, with millions of members today. Offshoots of this church continue today, though much of the world has little memory of this.
