from “The World’s Last Night,” Excerpt 2 of 7
Many are shy of this doctrine [of the Second Coming of Christ] because they are reacting (in my opinion very properly reacting) against a school of thought which is associated with the great name of Dr. Albert Schweitzer. According to that school, Christ’s teaching about his own return and the end of the world—what theologians call his “apocalyptic”—was the very essence of his message. All his other doctrines radiated from it; his moral teaching everywhere presupposed a speedy end of the world. If pressed to an extreme, this view, as I think Chesterton said, amounts to seeing in Christ little more than an earlier William Miller, who created a local “scare.” I am not saying that Dr. Schweitzer pressed it to that conclusion: but it has seemed to some that his thought invites us in that direction. Hence, from fear of that extreme, arises a tendency to soft-pedal what Schweitzer’s school has overemphasized.
