From the Scriptures

[They] shall teach the principles of my gospel, which are in the Bible and the Book of Mormon, in the which is the fulness of the gospel. And they shall observe the covenants and church articles to do them, and these shall be their teachings, as they shall be directed by the Spirit. Doctrine & Covenants 42:12-13

All who teach in the Church are to teach the fulness of the gospel: faith in Christ, repentance, baptism, arid the gift of the Holy Ghost as found in the standard works of the Church (D&C 33:12; 39:6; 3 Nephi 27:20-21; Hebrews 6:1-2). We are also blessed to continue to receive further light as part of the new and everlasting gospel covenant, light that expands our understanding of God’s plan of happiness (for example, the ordinances of the temple). Nevertheless, we are not to cast gospel pearls before unprepared or unappreciative individuals (D&C 41:6). We are to teach from the scriptures, bear testimony of the scriptures, and feast upon the doctrines and transcendent teachings found therein. We are to follow the living prophet and bear witness in word and deed of his counsel and teachings. We who teach—and every member of the Church is a teacher—must focus on gospel essentials and not stray away into speculative interests or gospel hobbies.. (Robert L. Millet and Lloyd D. Newell.
