* In addition to the Bible’s Old and New Testaments, they believe in the Book of Mormon — said to be the writings of ancient prophets who lived in North America from about 2200 BC to AD 421. The writings include an account of Jesus Christ in North America after his crucifixion and resurrection.
* Mormons believe these writings were recorded on gold plates ultimately buried in a hillside in what eventually became upstate New York; that an angel in 1823 led then-teenager Joseph Smith to those plates; and that Smith later transcribed them before returning them to the angel. Smith is the founder of the Mormon Church; the Book of Mormon was first published in 1830.
* Mormons believe the president of the Church of Jesus Christ of Latter-Day Saints is a prophet of God.
* Mormons believe God, Jesus Christ and the Holy Ghost are one in will and purpose but are not literally the same being or substance.
* Mormon church doctrine forbids consumption of alcohol, tobacco, tea, coffee and illegal drugs.
* Adult Mormons wear simple, white “temple garments” under their regular clothes as a private, symbolic reminder of their covenant with God.
* Mormons discontinued the practice of polygamy in 1890. A small number of fundamentalists, disavowed by the church, still practice it today.
