"Now, in fact Jesus and his words have never belonged to the categories of dogma or law, and to read them as if they did is simply to miss them. They are essentially subversive of established arrangements and ways of thinking. That is clear from the way they first entered the world, their initial effects, and how they are preserved in the New Testament writings and live on in his people. He himself described his words as “spirit and life” (John 6:63). They invade our “real” world with a reality even more real than it is, which explains why human beings then and now have to protect themselves against them.
He and his early associates overwhelmed the ancient world because they brought into it a stream of life at its deepest, along with the best information possible on the most important matters."
