The Church of Jesus Christ of Latter-day Saints was organized on April 6, 1830. In Doctrine & Covenants section 20, the basic doctrine and organization of the church is described. We learn the importance of the Book of Mormon in the Restoration, and that “God does inspire men and call them to his holy work in this age and generation, as well as in generations of old.” (D&C 20:11) We learn about the nature of God, that He is infinite and eternal, and the creator of heaven and earth, and of all men, male and female, and that we are created in His likeness. We learn that His Only Begotten Son is our Savior and that if we are baptized and believe in His name and endure in faith, we should be saved through His grace. 

We are also taught about baptism, including who should be baptized, how we should be baptized, and who has authority to baptize. We learn about the sacrament, who should administer it, and the prayers that should be used. 

In this section we learn the duties of elders, priests, teachers, and deacons. Each priesthood office has specific duties and keys that pertain to that office, and members of all priesthood offices should “warn, expound, exhort, and teach, and invite all to come unto Christ.” (D&C 20:59)
