Mormonism is the unofficial name for The Church of Jesus Christ of Latter-Day Saints, which originated in the early 1800s. Mormonism refers to the doctrines taught by Joseph Smith, doctrines that are believed to be original gospel preached by Jesus Christ. The Mormons oppose abortion, homosexuality, unmarried sexual acts, pornography, gambling, tobacco, consuming alcohol, tea, coffee, and the use of drugs. Despite its relatively young age, the Mormon Church continues to grow, and today it contains about 13 million members. The third edition of the Historical Dictionary of Mormonism expands on the second edition with a chronology, an introductory essay, a bibliography, and hundreds of cross-referenced dictionary entries on crucial persons, organizations, churches, beliefs, and events. Clearing up many of the misconceptions held about Mormonism and its members, this is an essential reference.
