The Church of Jesus Christ of Latter-day Saints (LDS Church) is the largest group in the Mormon movement. It was started in 1830 in New York by Joseph Smith. They believe that Joseph Smith was a prophet who restored the church Jesus Christ set up on earth when he was alive. They teach that they are the only church that has the full gospel. They also believe that the Father, Son and Holy Spirit are three separate individuals, but all have the same purpose. LDS scriptures include the Bible, the Book of Mormon, the Doctrine and Covenants, and the Pearl of Great Price. Members of the church, often called Mormons, and properly known as Latter-Day Saints are known for being active in missionary work. They also believe in the importance of families.
