Want to do a well-rounded engagement of Mormonism? Study and quote:
- General Conference talks
- “Correlated” priesthood and relief society manuals
- Institute and seminary manuals (what the teens and college students are being taught)
This is what makes Bill McKeever and Eric Johnson so awesome — they work hard to keep abreast of LDS literature, with a special focus on the manuals that are actually being used to teach Mormons.
And then, if possible:
- 19th century LDS scripture
- Popular literature found at Deseret Book, etc.
- Works of LDS neo-orthodoxy (generally BYU professors)
- “Mormon Doctrine”, by Bruce McConkie
- Works of James Talmage (pivotal theological figure of the “reconstruction era” of Mormon history)
- Dialogue: A Journal of Mormon Thought
It also helps to be able to summarize the historical development of a particular doctrine (using the term loosely here). A really helpful work on this is This Is My Doctrine: The Development of Mormon Theology, by Charles Harrell. Quoting from the Journal of Discourses (essentially the 19th century “Conference Reports”!) also is relevant when surveying historical LDS teachings.
A sloppy countercultist will overly depend on 19th century quotes of brazen leaders like Brigham Young and Orson Pratt. Conversely, a quasi-ecumenical liberal will tend to only quote from 19th century Mormon scripture and the works of neo-orthodox BYU professors.
