Brigham Young taught that Adam was an exalted being who came to earth from another world. His teachings are often called the “Adam-God theory” or “Adam-God doctrine,” though Young didn’t use either term. While The Church of Jesus Christ of Latter-day Saints has distanced itself from Young’s teachings, the Adam-God theory remains a point of debate among scholars, fundamentalist groups, and critics of the faith. In this interview, author Samuel Weber explores the evolution of Brigham Young’s teachings about Adam and God.
