Maybe I am too naive, but I think that the message of Jesus was deeply subversive. That it was not something people had heard or necessarily thought before in the way Jesus presented it, so therefore, it caused at first minor ripples, which turned into massive waves, crushing the messenger, i.e. Jesus himself. Jesus' own family saw something about his message which was subversive, and attempted to distract him from proclaiming the kingdom. His mother probably was saying, "Jesus, you are creating discomfort for the leaders, you are going to get in trouble for saying what you are saying, so be a "good" citizen and stop!" (Of course this is my translation). The amazing part of Jesus' message was that he was attempting to offer mercy and forgiveness to an entire nation of people, which would in turn offer mercy and forgiveness to the entire Cosmos in his name. How is that not being a "good" citizen? This is the reason that theologians such as N.T. Wright are so popular, not because every 'jot and tittle' of their theology is without criticism, but because they present Jesus' message within the context of 1st century Judaism where it belongs. This enhances our understanding of Jesus' resurrection as his defeat of sin and death. If we only read our worldview, i.e. Western culture, division of church and state, Deism, materialism, consumerism into our understanding of Jesus, we have made Jesus into our own IMAGE. That is serious, because we will end up losing out on the incredible offer of participation with the God who cares deeply for all things in this world.
We will limit God to only being able to work within our thoughts and culture. Jesus' proclamation was not accepted in his day as it not in our day, because I suspect that it was thought of as weakness. At least the apostle Paul thought that it was weakness. That weakness was what would have saved an entire nation from possible destruction. (Matthew 5) Does it make a difference today? Why are we afraid of weakness? If we deny our weaknesses, insecurities, fears, we will only rely on violence to bring what we think is peace. That is what Rome was. We have to remember that if we rely on violence, the stronger will always defeat the strong in the paradigm of violence. I think that Jesus thought that violence never defeats the violent. He thought that the cross defeats the manifestation of evil, which is violence.
