Who is Jesus Christ from Jesus: A Revolutionary Biography and what is their importance?

In the Bible, and specifically in its New Testament, Jesus Christ is portrayed as The Messiah, the person who, according to Jewish theological tradition will lead the faithful from their earthly sins into a more spiritual existence. While Jewish tradition holds that that person has not yet appeared on earth, according to Christian theological tradition, the man known as Jesus was that person. This book, however, is less interested in either tradition and more in the social, historical and political contexts of the man Jesus' life, work, teaching, and death.
