The Church of Jesus Christ of Latter-day Saints, informally known as the LDS Church or Mormon Church, is a nontrinitarian restorationist Christian denomination and the largest denomination in the Latter Day Saint movement. Founded during the Second Great Awakening, the church is headquartered in Salt Lake City, Utah, and has established congregations and built temples worldwide. According to the church, as of 2024, it has over 17.5Â million members, of which over 6.8Â million live in the U.S. The church also reports over 109,000 volunteer missionaries and over 200 dedicated temples.
Church theology is restorationist and nontrinitarian; the church is a Christian denomination and includes a belief in the doctrine of salvation through Jesus Christ and his substitutionary atonement on behalf of mankind. It is often included in the lists of larger Christian denominations, though most Catholics, Orthodox Christians and evangelicals, and some Mainline Protestants have considered the LDS Church to be distinct and separate from mainstream Christianity. The church has an open canon of four scriptural texts: the Holy Bible, the Book of Mormon, the Doctrine and Covenants (D&C), and the Pearl of Great Price. Other than the Bible, the majority of the church canon consists of material believed by the church's members to have been revealed by God to Joseph Smith, including texts described as lost parts of the Bible, and other works believed to have been written by ancient prophets, including the Book of Mormon. Members adhere to church laws of sexual purity, health, fasting, and Sabbath observance, and contribute ten percent of their income to the church in tithing. The church teaches ordinances through which adherents make covenants with God, including baptism, endowment, and celestial marriage.
