The Church just released this information today:
The Church takes no position on the specific geographic location of Book of Mormon events in the ancient Americas. Church members are asked not to teach theories about Book of Mormon geography in Church settings but to focus instead on the Book of Mormon’s teachings and testimony of Jesus Christ and His gospel.
The Book of Mormon includes a history of an ancient people who migrated from the Near East to the Americas. This history contains information about the places they lived, including descriptions of landforms, natural features, and the distances and cardinal directions between important points. The internal consistency of these descriptions is one of the striking features of the Book of Mormon.
Since the publication of the Book of Mormon in 1830, members and leaders of The Church of Jesus Christ of Latter-day Saints have expressed numerous opinions about the specific locations of the events discussed in the book. Some believe that the history depicted in the Book of Mormon occurred in North America, while others believe that it occurred in Central America or South America. Although Church members continue to discuss such theories today, the Church takes no position on the geography of the Book of Mormon except that the events it describes took place in the Americas.
The Prophet Joseph Smith himself accepted what he felt was evidence of Book of Mormon civilizations in both North America and Central America. While traveling with Zion’s Camp in 1834, Joseph wrote to his wife Emma that they were “wandering over the plains of the Nephites, recounting occasionally the history of the Book of Mormon, roving over the mounds of that once beloved people of the Lord, picking up their skulls and their bones, as a proof of its divine authenticity.”1 In 1842, the Church newspaper Times and Seasons
published articles under Joseph Smith’s editorship that identified the ruins of ancient native civilizations in Mexico and Central America as further evidence of the Book of Mormon’s historicity.2
Anthony W. Ivins, a Counselor in the First Presidency, stated: “There has never been anything yet set forth that definitely settles that question [of Book of Mormon geography]. So the Church says we are just waiting until we discover the truth.”3The Church urges local leaders and members not to advocate theories of Book of Mormon geography in official Church settings. Speaking of the book’s history and geography, President Russell M. Nelson taught: “Interesting as these matters may be, study of the Book of Mormon is most rewarding when one focuses on its primary purpose—to testify of Jesus Christ. By comparison, all other issues are incidental.”4
