What happens when the Book of Mormon slips into the public domain and someone entirely outside the faith decides to publish it? In this episode of the Sunstone Mormon History Podcast, Lindsay and Bryan trace the strange journey of an 1858 “unauthorized” edition, a scrappy little volume caught between evolving copyright law, religious rivalry, and the chaos of the post-Nauvoo moment. What starts as a quirky catalog find quickly becomes a story of opportunistic publishers, anti-Mormon agendas, and a network of “Never Brigham” believers trying to reclaim the text for themselves. Along the way, a little-known New York publisher markets the book like a sales scheme, a U.S. senator proposes distributing it to undermine Mormonism, and Zadoc Brooks rewrites the introduction to turn it into a direct challenge to Brigham Young and polygamy. Threaded through it all are Martin Harris’s wandering years and the early formation of RLDS identity, revealing a moment when authority over the Book of Mormon, and Mormonism itself, was anything but settled.
