The CES Letter is an 84-page document written by Jeremy Runnells, a former member of the Church of Jesus Christ of Latter-day Saints (LDS Church), who sought official answers from the LDS Church on its troubling origins, history, and practices. The letter outlines a large list of issues Runnells has with LDS Church beliefs and its historical narrative, mostly dealing with historical issues. The CES Letter has been translated into several languages and has gained attention both inside and outside the LDS community. While some have praised the CES Letter for its thoroughness and honesty, others have criticized it for being one-sided and overwhelming readers with negative information. The CES Letter has become a polarizing document, and its impact on the LDS Church and its members is a topic of ongoing debate.
