Christianity and other religions claim that their books and creeds contain truths revealed by God. How can we know whether they do? Revelation investigates the claim of the Christian religion to have such revealed truths; and so considers which parts of the Bible are to be regarded as literal history, and which as metaphorical truth. This entirely rewritten second edition contains a long new chapter examining whether traditional Christian claims about personal morality (divorce, homosexuality, abortion, etc.) can be regarded as revealed truths.
