Phillips summarizes the evangelistic distinctions between the disciples of Christ and the disciples of Caesar:
But whereas the Caesars sought to Romanize the world through brutality, force, and bloodshed, the Christians sought to evangelize the world through love, self-giving, and sacrifice. The glad tidings of Jesus were therefore bad news for Caesar, since it proclaimed there was another way to transform the world that was superior to Caesar’s way. It announced that God had called out a people whose vocation was to work for peace and justice on Jesus’ terms, not Caesar’s (43).
