The Doctrine and Covenants is a collection of revelations and writings that are considered scripture by members of the Church of Jesus Christ of Latter-day Saints (LDS Church). It contains teachings, instructions, and guidance given to early church leaders, including Joseph Smith, the church's founder. The text addresses various aspects of faith, governance, and the organization of the church. First published in 1835, the Doctrine and Covenants has undergone several revisions and expansions over the years. It is unique among Latter-day Saint scriptures, as it includes modern revelations rather than ancient texts. The book serves as a foundational document for church doctrine and practice, emphasizing the importance of ongoing revelation.
