The Doctrine and Covenants is a collection of divine revelations and inspired declarations primarily received by Joseph Smith, the founder of the Latter Day Saint movement. First published in 1835, it serves as a guide for the establishment and governance of the Church of Jesus Christ of Latter-day Saints. The book includes 138 sections and two official declarations, covering a wide range of topics such as church organization, temple work, and eternal families. Unlike the Bible and the Book of Mormon, the Doctrine and Covenants is considered an open canon, meaning new revelations can be added.
