Christians are deeply concerned about consumerism, but lack the tools to be able to engage robustly in the debate about its future. Economists obfuscate, politicians polarise, and church leaders bluff. While desire to consume is a fundamentally human trait, consumerism offers only illusory satisfaction. Yet Christianity happens to be unusually well-equipped to lead the fight against Mammon's most alluring secular narratives. Consumerism is human action, so it can as easily be redemptive as it can be parasitical. We just need to consume for God instead. Drawing on the Church's rich traditions of Social Liturgy, 'Buying God' calls on the Christian community to renew its confidence and strength in proclaiming this good news. Uniting theoretical work on theology, capitalism and consumerism with a scheme of detailed practical action, the book explores how we can wean ourselves off the material and on to the eternal, through prayer, example, and vibrant social action.
