That appearance on earth as an individual is the crisis in the history both of Christ Himself and of the humanity He saves and leads. The ministry of Jesus, therefore, culminating in His death, is essential to Paul's whole thought. If in certain aspects of his theology it is the death that bulks most largely -- because it seemed to him to be the purest and most moving expression of what the whole life meant -- he is quite aware that the ethical impulse given by the example and teaching of Jesus is of the very stuff of the Christian life. He alludes to the Gospel story but sparingly, but those who study his teaching most closely become aware that he is himself acting and speaking all through under the impulse of the life and teaching of Jesus. If he refuses to "know Christ after the flesh," it means that he will not risk a harking back to the temporary conditions of the Galilean ministry when the Spirit of Christ is clearly leading out into new fields. The issues of that ministry have been gathered up in the new experience of "Christ in me", and that experience gives a living Christ, who leads ever onward those who will adventure with Him, and not a prophet of the past, whose words might pass into a dead tradition.
