Doctrine and Covenants (1835) is the second of three works (along with Book of Mormon and Pearl of Great Price) by Joseph Smith, Jr., the founder of the Church of Jesus Christ of Latter-day Saints (LDS). Doctrine and Covenants is a collection of revelations given to Smith during the 1830s. The content of these revelations ranges from the organization and impetus of the church to specific commandments, such as the proper role and titles of individuals in the LDS church (who are commonly called Mormons), to various theological doctrines.
