Frontline and American Experience did a four-hour documentary on Mormonism which you can watch online. The program did a commendable job of presenting history mingled with assorted points of view in such a way that you are left with feelings ranging from unsympathetic skepticism to deep respect towards this prominent American-born religion.
Less compliementary is Christopher Hitchens’ exposition of the Mormon faith on Slate (an excerpt from his book God Is Not Great).
Not to give the impression that this is the only guy I’m reading, but Hitchens tickles me almost every time. He will go right out and make the most politically incorrect statements girded by a thick and extensive foundation of documented facts and raw logic so intimidating that all the true believer can do in response is get angry and walk off. I love it 🙂 But I don’t think my Mormon friends will be as amused as I am.
