Like every lost world the world of the early Christians was a combination of the foreign and the familiar, the unique and the commonplace. In The World of the Early Christians, Joseph Kelly introduces and explains the world of the early Christians, and while he examines the differences between our two societies, he also stresses our similarities. The early Christians were people, like us, trying to make their way in life. There are many introductions to the world of the early Christians, but few if any deal with its historical background and the basic questions non-specialists ask: Why did the Christians use philosophy at all? Didn't it make everything confusing? Why didn't they just stay with the Bible? In The World of the Early Christians Kelly answers such preliminary questions and concentrates on the fundamental issue of why Christians used philosophy, rather than simply listing the philosophies they used.
