Abstract
This chapter shows how a cumulative case for theistic belief is already moving from considerations of natural theology to considerations of revealed theology, as one attempts to do justice to a wide range of historical data on the history of religions. Sense has to made of the widespread phenomenon of religious experience. Morality, too, is found to be more intelligible in a theistic context than within a purely naturalistic worldview. Further arguments for theism from value include appeals to the objectivity of beauty and truth. But the diversity of world religions presents a problem for the rationality of any one doctrinal system. Christianity, like any other faith, has to provide a theology of religion and the religions if its particular and unique claims are to be rationally justified.
