모르몬경, also known as the Book of Mormon, is a sacred text of the Latter Day Saint movement, which was founded by Joseph Smith in the early 19th century. It is considered by followers to be a companion to the Bible and is believed to contain the writings of ancient prophets who lived in the Americas. The book narrates the history of several groups of people, including the Nephites and Lamanites, and their interactions with God. It emphasizes themes of faith, repentance, and the teachings of Jesus Christ, who is said to have visited the Americas after his resurrection.
