Symbolism and Belief and Holy Images, based on Bevan’s Gifford Lectures, examines the relationship of symbolical conceptions to unseen Reality or Divine Being, explaining how religious beliefs have been interpreted literally or/and symbolically. He reviews the different approaches to religious symbols from the ancient Greek philosophy through the medieval period to contemporary world religions. Symbolism is well balanced in the sense that it analyzes concrete symbols like height, time, light, spirit and the wrath of God, while discussing general theories of religious symbols and concluding that belief in God can be justified not by reason but by faith alone. Holy Images deals with idolatry and image-worship in ancient paganism and in Christianity.
