This book gives a personal insight into the hearts and minds of a fundamentalist Christian sect, the Open Brethren. Using Brethren magazine articles, obituaries, and testimonies, Peter Herriot argues that the Brethren constitute a perfect example of a fundamentalism. Their culture is entirely opposed to the beliefs, values, and norms of modernity. As a result, like other fundamentalisms they challenge modern Christianity and impede its efforts to engage with global society.

Peter Herriot, who was brought up in a Brethren family, was Professor of Psychology at the City University and at Birkbeck College, University of London. He has since written on fundamentalism from a social psychological perspective. Among his books are 'Religious Fundamentalism: Global, Local, and Personal' (2009) and 'Warfare and Waves: Calvinists and Charismatics in the Church of England' (2017).
