Is there a universal concept of God? Do all the great faiths of the world share a vision of the same supreme reality? In an attempt to answer these questions, Keith Ward considers the doctrine of an ultimate reality within five world religions - Hinduism, Buddhism, Islam, Judaism and Christianity. He studies closely the works of definitive, orthodox writers from each tradition - Sankara, Ramanuja, Asvaghosa, Maimonides, Al-Ghazzali and Aquinas - to build up a series of 'images' of God, a common core of belief. Ward discovers that while the great religious traditions of the world retain their differences, there are convergences of thought at the deepest level, with a broad similarity of structure in concepts of God. He concludes that a recognition of these beliefs, as well as encouraging a clearer acceptance of the mystery of the divine, might also lead to an increase in understanding and tolerance of other faiths, to the enrichment of one's own.
