"Jesus himself, and most of the message of the Gospels, is a message of service to the poor, a critique of the rich and the powerful, and a pacifist doctrine. And it remained that way, that's what Christianity was up ... until Constantine. Constantine shifted it so the cross, which was the symbol of persecution of somebody working for the poor, was put on the shield of the Roman Empire. It became the symbol for violence and oppression, and that's pretty much what the church has been until the present."
