The Doctrine and Covenants: A collection of latter-day divine revelations and inspired declarations.
The Lord gave these to Joseph Smith and several of his successors for the establishment and regulation of the kingdom of God on the earth in the last days. The Doctrine and Covenants is one of the standard works of scripture in The Church of Jesus Christ of Latter-day Saints, along with the Bible, the Book of Mormon, and the Pearl of Great Price. The Doctrine and Covenants is unique, however, because it is not a translation of ancient documents; the Lord gave these revelations to his chosen prophets in this modern day in order to restore his kingdom. In the revelations, one hears the tender but firm voice of the Lord Jesus Christ (D&C 18:35–36).
Joseph Smith’s history says that the Doctrine and Covenants is the foundation of the Church in the last days and a benefit to the world (D&C 70 heading). The revelations in it initiate the work of preparing the way for the Lord’s Second Coming, in fulfillment of all the words spoken by the prophets since the world began.
The Pearl of Great Price: The kingdom of God on earth is likened to a “pearl of great price” (Matt. 13:45–46).
The Pearl of Great Price is also the name given to one of four volumes of scripture called the “standard works” of The Church of Jesus Christ of Latter-day Saints. The first edition of the Pearl of Great Price was published in 1851 and contained some material that is now in the Doctrine and Covenants. Editions published since 1902 contain (1) excerpts from Joseph Smith’s translation of Genesis, called the book of Moses, and of Matthew 24, called Joseph Smith - Matthew; (2) Joseph Smith’s translation of some Egyptian papyrus that he obtained in 1835, called the book of Abraham; (3) an excerpt from Joseph Smith’s history of the Church that he wrote in 1838, called Joseph Smith - History; and (4) the Articles of Faith, 13 statements of belief and doctrine.
