This volume consists of a critical commentary on the interactions between Marxism and theology in the work of the major figures of Western Marxism. It deals with the theological writings of Ernst Bloch, Walter Benjamin, Louis Althusser, Henri Lefebvre, Antonio Gramsci, Terry Eagleton, Slavoj Zizek and Theodor Adorno. In many cases their theological writings are dealt with for the first time in this book. It is surprising how much theological material there is and how little commentators have dealt with it. Apart from the critical engagement with the way they use theology, the book also explores how their theological writings infiltrate and enrich their Marxist work. The book has three parts: Biblical Marxists (Bloch and Benjamin), Catholic Marxists (Althusser, Lefebvre, Gramsci and Eagleton), and the Protestant Turn (Zizek and Adorno).
