Book excerpt: Hans Mol's imprisonment by the Gestapo during World War II began a long intellectual journey, exploring the role of religion in society. Part One of this book includes a brief outline of Mol’s most influential theory, explicated in Identity and the Sacred (1976). Part Two is comprised of four previously-unpublished essays written by Mol during the 70s and 80s, covering topics from evolution to evangelicalism. This volume concludes with transcripts of interviews conducted with Hans Mol during 2012. This volume of Mol’s work will be of keen interest to academics and students with an interest in the sociology of religion post-World War II and the development of contemporary Christian theology.
