There was a human being in the first century who was called “Divine,” “Son of God,” “God,” and “God from God,” whose titles were “Lord,” “Redeemer,” “Liberator,” and “Savior of the World.” Who was that person? Most people who know the Western tradition would probably answer, unless alerted by the question’s too-obviousness, Jesus of Nazareth. And most Christians probably think that those titles were originally created and uniquely applied to Christ. But before Jesus ever existed, all those terms belonged to Caesar Augustus. To proclaim them of Jesus the Christ was thereby to deny them of Caesar the Augustus. Christians were not simply using ordinary titles applied to all sorts of people at that time, or ever extraordinary titles applied to special people in the East. They were taking the identity of the Roman emperor and giving it to a Jewish peasant. Either that was a peculiar joke and a very low lampoon, or it was what the Romans called majestas and we call high treason.
