D.G. Hart is an insightful historian who has spent significant time studying church history and theology. He has worked for, and been associated with, Hillsdale College, Westminster Theological Seminary and the Intercollegiate Studies Institute. He is the author of at least 9 books, including Recovering Mother Kirk: A Case for Liturgy in the Reformed Tradition (2003), The Lost Soul of American Protestantism (2004) and From Billy Graham to Sarah Palin: Evangelicals and the Betrayal of American Conservatism (2011). Mr. Hart has some very interesting things to say about the relations between church and state. But, even more interesting is his commentary concerning the historical relationship between traditional conservatism and the religious right.
