Ask and answer the big questions about the role of Christianity in Britain. Is Christianity being forced out of mainstream British society? From restrictions on the wearing of crosses to the abolition of Christmas nativity plays, a secular tradition is being introduced piecemeal into our way of life. Christianity is being marginalised. Christian social initiatives at local levels are now so severely restricted that several Christian bodies issue guidelines on handling local council prejudice. Is Britain's Christian heritage is slipping away? For centuries the Bible and Book of Common Prayer have been the foundation of British, language, literature and culture. Social action and welfare motivated and mobilised by Christian organisations predate the modern welfare state and British law is founded on a Christian system of ethics. Should Christians push back, re-engaging with politicians and opinion formers? George Carey, Archbishop of Canterbury from 1991 to 2002 and his freelance journalist son, Andrew, show that if Christians are still the salt and light of British society then introverted Christianity must give way to engagement not defensively, but with confidence and hope. time for a proper debate about the role of faith in modern Britain.
