Mormonism is the common name for the Latter Day Saint movement, a 19th‑century American religious tradition that describes itself as a restoration of early Christianity. Adherents identify as Christian and the movement is usually described as Christian and restorationist in orientation; it began as a distinct religious movement under the leadership of Joseph Smith and gave rise to several churches, the largest of which is The Church of Jesus Christ of Latter‑day Saints. The term "Mormon" historically refers to followers of doctrines associated with the Book of Mormon, a scripture unique to the movement.

Beliefs and scriptures

Core beliefs combine elements familiar to many Christian traditions—faith in Jesus Christ, prayer, and scripture—with distinctive teachings about prophetic restoration, continuing revelation, and the nature of God and humanity. Latter Day Saints accept the Bible (in translation), but also regard several other texts as scripture. Important writings include:

  • The Book of Mormon (presented as another testament of Jesus Christ)
  • Doctrine and Covenants (revelations and ecclesiastical guidance)
  • Pearl of Great Price (a compilation of additional writings and translations)

Other distinctive doctrines concern priesthood authority, the importance of covenants, ordinances performed in temples, and an emphasis on family relationships as central to spiritual life.

Organization and practices

The movement is not a single church but a family of denominations and groups. The largest, The Church of Jesus Christ of Latter‑day Saints, has a hierarchical structure with lay clergy, organized local congregations (wards and branches), and global leadership. Common practices include regular worship services, missionary work, scripture study, and a program of welfare and humanitarian service.

Temple rites—distinct from weekly worship—include ceremonies such as baptisms for the deceased, endowments, and sealings for families. These rites are regarded as sacred and are performed in purpose‑built temple buildings by qualified members.

History and development

Joseph Smith founded the movement in the 1820s–1830s in the northeastern United States, claiming visions and revelations that led to the publication of the Book of Mormon in 1830. Early history included rapid growth, internal schisms, controversy, and migrations of followers westward under leaders such as Brigham Young. In the late 19th century, some practices—most notably plural marriage—became a source of conflict with broader American society; mainstream branches later abandoned polygamy.

Contemporary presence and diversity

Today the movement is international and diverse. While the largest church remains headquartered in Utah, communities and related denominations exist worldwide with varying doctrines and practices. Members are often active in civic life, and the churches operate extensive welfare, educational, and humanitarian programs.

Distinctions and public perceptions

Mormonism sits at the intersection of shared Christian traditions and distinct theological claims, which has prompted debate over its classification as Christian among scholars and the public. Some objections focus on unique scriptures and doctrines, while members emphasize their commitment to Jesus Christ. The movement's history, growth, and cultural impact continue to make it a significant subject in studies of American religion and global faith movements.
