This book asks thequestion 'what is religion?' from a theological perspective. In an age in whichreligion has reasserted itself on national and international stages, Theology against Religion argues that weshould take seriously the critique of religion, and engage with that critiquetheologically. The book argues that theologizing the critique of religion wascentral to the theological purposes of Karl Barth and Dietrich Bonhoeffer, andthat Barth and Bonhoeffer should be seen as traveling along the sametrajectory in terms of their theological approaches to religion. It is thistrajectory that this book seeks to explore in thinking with and beyondBonhoeffer, and by identifying a series of themes around which constructionengagements can take place. The result is an exciting series of discussionswhich take seriously the interplay of the religious, the secular, pluralism andthe concept of God, with chapters on salvation, the church, the public squareand other faiths.
