Biblical scholars and theologians such as John Howard Yoder have helped us see that the coming of Jesus was indeed political. Jesus' coming had to do with all of life, not just with the inner world of the individual. The kingdom of God come in Jesus brings in the beginning of the new creation and this began at the coming of Jesus: his Incarnation, life and ministry, death, resurrection, ascension and pouring out of the Spirit at Pentecost.
Jesus' coming said, in a day when Casear was considered both "son of God" and "Lord", that those titles belong to Jesus. Yet at the same time Jesus taught to give to Caesar what belongs to Caesar and to God what belongs to God. Jesus seemed uninterested in dealing directly with the powers and trying to be a part of the world system. Instead he speaks of a kingdom not from this world and not living according to it. This is the heart of his kingdom come and now present "in Jesus" and in those who are in Jesus, his church.
To say Jesus' coming and the kingdom of God is political is to say that it really is concerned about all of life: the personal, communal and systemic; local, national and international. But it is one that infiltrates, I believe, especially through the people of God in Jesus, the church and the church's act and proclamation of the good news of Jesus in the world. And in the tradition of Daniel, Esther and early Christians in various stations of life, it is one that is salt and light in whatever corner or calling one is found in, and having potentially a major impact for its time.
I believe Jesus' coming is subversive in a transformative way within the system. It makes a big difference potentially even now. Herod could have been a part of that if he would have bowed his knees in repentance to the newborn king. In fact no matter what form of government is in play in this world, even in most trying circumstances brought on by it, acknowledging the King of kings and Lord of lords, the one exalted over all- can help in this world and existence to make a difference. But it's one of a subtle nature through the church and through members of the church at work in society. Not one of directly overthrowing this world order, which awaits the return of Jesus to this world, the Second Advent.
These are rather preliminary thoughts I have on this. Have you thought about this, and whether you have or not, what would you like to share here?
