The Church of Jesus Christ of Latter-day Saints (the LDS Church or, informally, the Mormon Church), was organized in 1830. As of 2010 the Church had a worldwide membership of approximately 14 million people. The Church headquarters is in Salt Lake City, Utah. Mormons believe the Bible and Jesus’s teachings in revelations to modern-day apostles and prophets. Mormons believe that their Church is the same as the original Church Jesus established when He was on the earth (see Ephesians 2:19–20; 4:11–14). The name “Mormon” is a nickname that comes from the Church’s belief in the Book of Mormon (ancient scripture revealed to and recorded by prophets in the Americas during the same time the Bible was being written in the Old World).
