That Old-Time Religion in Modern America: Evangelical Protestantism in the Twentieth Century is by D. G. Hart, a historian and member of an evangelical church, the Orthodox Presbyterian Church.
The book is ok. It's a highly readable narrative of the move of born-again Christians from the shame of the Scopes trial to the prominence of the Christian Coalition. Hart's argument that evangelical pietism has led to many conundrums for modern-day evangelicals (who piously refuse to keep their faith separate from other areas of "secular" life) is a reasonable explanation for their tense relationship with modernity.
He also argues that fundamentalists and evangelicals preserve the basic character of Christianity from the American past while Liberals and other non-evangelical Christian groups have been the ones who have deviated from the historical norm. This argument, besides being pretty incredible, is not supported with evidence in this book. To my mind, all Christians in America had to change to deal with science, modern historical methods, and biblical criticism. Even retrenchment is a kind of change. Hart's failure to see how the "old-time religion" is also a construction of modernity keeps the book from being truly a worthwhile read.
