In orthodox Mormonism, the term God generally refers to the biblical God the Father, whom Latter Day Saints also refer to as Elohim or Heavenly Father, and the term Godhead refers to a council of three distinct divine persons consisting of God the Father, Jesus Christ, and the Holy Ghost. However, in Latter Day Saint theology the term God may also refer to, in some contexts, the Godhead as a whole or to each member individually. Latter Day Saints believe that the Father, Son and Holy Ghost are three distinct beings, and that the Father and Jesus have perfected, glorified, physical bodies, while the Holy Ghost is a spirit without a physical body. Latter Day Saints also believe that there are other gods and goddesses outside the Godhead, such as a Heavenly Mother—who is the wife of God the Father—and that faithful Latter-day Saints may attain godhood in the afterlife. The term Heavenly Parents is used to refer collectively to the divine partnership of Heavenly Father and a Heavenly Mother. Joseph Smith taught that God was once a man on another planet before being exalted to Godhood.

Mormonism is the theology and religious tradition of the Latter Day Saint movement of Restorationist Christianity started by Joseph Smith in Western New York in the 1820s and 1830s. As a label, Mormonism has been applied to various aspects of the Latter Day Saint movement, although there has been a recent push from the Church of Jesus Christ of Latter-day Saints to distance themselves from this label. A historian, Sydney E. Ahlstrom, wrote in 1982 that, depending on the context, the term Mormonism could refer to “a sect, a mystery cult, a new religion, a church, a people, a nation, or an American subculture; indeed, at different times and places it is all of these."
