Steven Waldman has produced an excellent overview of the development of religious liberty in the United States. It is well-written, as one would expect of a journalist (the Beliefnet.com founder is a veteran of Newsweek, among other publications), but also well-researched and reasonably nuanced. Experts on particular eras or subjects will find details about which they can justly complain, but on the whole, Sacred Liberty: America’s Long, Bloody, and Ongoing Struggle for Religious Freedom deserves high marks.
