The Doctrine and Covenants is a part of the scriptural canon the Latter Day Saint movement. This 1880 edition contains two parts. First are the "Lectures on Faith," which set forth basic church doctrine. Second are the "Covenants and Commandments," a compilation of revelations, or "covenants" of the church. The Lectures on Faith were removed from later editions of the book, as they are not considered canonical by most Latter Day Saints.
