Despite the increasingly secular nature of modern life, religion remains a powerful factor in society. The readings in this volume present the Marxist view of the question, focusing on Christianity and the Western experience. What are the material roots of religion? What has been the role of the Christian church in history? What role has religion played in social struggles in the past? How should Marxist socialism relate to religion and religious believers? Can Christians be socialists and Marxists? Will there be a place for religion in a socialist society? These are some of the major questions addressed in this collection of classic writings by Karl Marx, Frederick Engels, Rosa Luxemburg, V.I. Lenin and Leon Trotsky.
