"One of the great achievements of Hart"s biography is his contextualization of Machen, in which these anomalies resolve themselves into a coherent if not always attractive personality... What makes Hart"s achievement remarkable is the skill with which he has synthesized these interpretive pieces into a readable and compelling narrative."--Allen C. Guelzo, Christianity Today."Hart"s portrait of Machen provides a novel perspective that merits the attention of those interested not just in fundamentalism but in the place of faith in modern America."--Bradley J. Longfield, Christian Century.
