Now comes the understatement: The people in the congregation, having witnessed a scene to rival anything in The Exorcist, look around at each other and say, "What is this? ... A new teaching!"
A new teaching? If this had happened in any congregation I know, they may have sat for hours in stupefied silence, they may have rushed to the altar in sudden repentance, or they may have jumped out of the church windows in terror, but the last thing they would have done was to comment on how this casting out of a demon constituted an innovation in Christian education. A new teaching? Indeed.
To call such an extraordinary event of the casting out of a demon a new teaching, well, I think that constitutes understatement for most of us because our ordinary experiences of teaching are so dull. So much of our teaching and learning involves stuff that is on the periphery of our lives. We may need to know it, but it doesn't exactly hit the core of us, the things which most centrally define us as persons. It doesn't move us, change us, make us new persons.
Christ's teaching, on the other hand, transform us. Just ask the demon-possessed man, ask the apostle Paul, ask Martin Luther, ask John Wesley. You could describe this as a new teaching but better yet describe it as God with us. For if God is with us, that changes everything.
