Paul: The Mind of the Apostle by A. N. Wilson
Jesus was no Christian, and his friends made no effort to break away from Jesus' religion, Judaism. What we call Christianity began with a Jew from Eastern Turkey known to the world as Paul of Tarsus. This book tells a story, not of a man who set out to found a new religion called Christianity, but of a visionary Jew who had a revolutionary idea of what it meant to be Jewish. The book sees Paul as the first of the great romantic poets, the man who made the crucified Jesus his inner light, and in so doing preserved the image of Christ the Saviour for posterity.
