Without fully and consciously realizing that they were doing so, the followers of Jesus established a new religious tradition. This book tells the story of yet another assembly of saints whose history, I believe, is in many respects analogous to the history of those early Christians who thought at first that they had found the only proper way to be Jews. Mormonism started to grow away from traditional Christianity almost immediately upon coming into existence. It began as a movement that understood itself as Christian, but. . . these nineteenth-century Latter-day Saints (as they came to be called) embarked on a path that led to developments that now distinguish their tradition from the Christian tradition as surely as early Christianity was distinguished from its Hebraic context.--From the preface
