Book excerpt: The Death of Christian Britain uses the latest techniques to offer new formulations of religion and secularisation and explores what it has meant to be 'religious' and 'irreligious' during the last 200 years. By listening to people's voices rather than purely counting heads, it offers a fresh history of de-christianisation, and predicts that the British experience since the 1960s is emblematic of the destiny of the whole of western Christianity. Challenging the generally held view that secularization has been a long and gradual process beginning with the industrial revolution, it proposes that it has been a catastrophic short term phenomenon starting with the 1960's. Is Christianity in Britain nearing extinction? Is the decline in Britain emblematic of the fate of western Christianity? Topical and controversial, The Death of Christian Britain is a bold and original work that will bring some uncomfortable truths to light.
