(CNN)Here's a look at the Church of Jesus Christ of Latter-day Saints.
Joseph Smith Jr. (December 23, 1805-June 27, 1844) founded the Church of Jesus Christ of Latter-Day Saints around 1830. He is seen as a living prophet.
"The Book of Mormon" is believed to be the result of Joseph Smith's communion with the divine.
It is also the source of the common nickname for the church and its followers, Mormons.
Joseph Smith claimed to have begun receiving messages at age 14 from God, Jesus Christ and other heavenly messengers.
Mormons consider themselves to be Christians. They follow the teachings found within the Christian "Bible," "The Book of Mormon," "Doctrine and Covenants" and "Pearl of Great Price."
"The Book of Mormon" tells the story of Israelites who left Jerusalem around 600 BC and traveled to North America after a calling from God. They set up civilizations, and centuries later witnessed an appearance by Jesus Christ after his crucifixion and resurrection.
They believe that God sent many prophets to spread his word after Jesus Christ's death and resurrection.
The church is led by a prophet who also serves as president of the church. The president serves for life.
The church's organizational hierarchy is the all-male General Authorities: the First Presidency (the president and two counselors), the Quorum of the Twelve Apostles, the First Quorum of the Seventy, the Second Quorum of the Seventy and the Presiding Bishopric (the bishop and two counselors); and the General Auxiliaries: the Primary, the all-female Relief Society, Sunday School, Young Men and Young Women.
Children are baptized at age eight. New members are also baptized.
There are two orders of priesthood. A young man 12 or older can enter into the Aaronic priesthood, seen as an earthly priesthood. Melchizedek priesthood can be obtained when a man turns 18. This entails spiritual and heavenly duties.
Follow a strict health code that prohibits the consumption of tobacco, alcohol, tea and coffee.
They are encouraged to tithe - giving 10% of their earnings to the church.
Many church members, between the ages 18 and 25 for males and 19 and 25 for females, become missionaries. Single men serve for two years; single women for 18 months.
The church is headquartered in Salt Lake City.
