"And meanwhile let us learn to reconcile ourselves to this outstanding sign of the times: eschatology has become the large mountain of offense lying across the pathway of modern unbelief. That part of it which we call Messiahship was already a piece broken from the rock in the days of Jesus. The double offense was at bottom. Neither will be tolerated in modern religious thought. And the results will inevitably be the same. Paul divorced from his eschatology becomes unfit for his Apostleship; Jesus divested of his Messiahship can no longer serve us as Savior."
