This is a very informative book about what the Latter Day Saints teach and practice. Jackson has certainly done his homework, which is evident as he spells out clearly what Mormon's believe and why they believe the way they do. While it is full of information, the author has a very easy-to-read style. Mormonism Explained is one of the most thorough books on Mormonism I ever read. It covers their history, beliefs, theology, and their diversity in beliefs. This book clears up some confusion I had about what Mormons really believe.I want to note that Jackson does not put down Mormonism as he explains their beliefs, not as a critic but as a teacher. It is a good book for those who want more insight into this religion.
