Nephi, what are some good mormon theologians vis a vis mormonism?
The ones that immediately come to mind are James Talmage and Bruce McConkie.
James Talmage's Jesus the Christ
is a biography of Christ's entire life according to the LDS, starting at the pre-earth councils and what-not. His other works are pretty commonly read too.
Bruce McConkie is famous, or perhaps infamous, for his Mormon Doctrine
, which most of the apologists against the LDS cite from a lot.
