Theology today can mean anything from reverence for the living God to the proposition that God is dead. How has the 'science of thinking about God' reached this dilemma? The Pelican Guide to Modern Theology, which is under the general editorship of Professor R.P.C. Hanson, discusses the outlook of modern Christian thinker and their attitude to the work of past theologians. Its three volumes, which examine the very foundations of Christianity in such questions as 'What and how is God?' cover the philosophy of religion , historical theology, and the study of the Bible: they help to explain why, even in these secular days, some people find theology the most attractive, exacting and satisfying intellectual pursuit of all.
