Theology is well aware that the God of the Gospel has a genuine interest in human existence and, in fact, awakens and calls man to faith in him; it knows that in this way God claims and arouses man’s entire spiritual capacity, more, in fact, than his spiritual capacity. But theology is interested in all this because it is primarily and comprehensively interested in God himself. The dominate presupposition of its thought and speech is God’s own proof of his existence and sovereignty. If theology wished to reverse this relationship, and instead of relating man to God, related God to man, then it would surrender itself to a new Babylonian captivity.

In reply to Emil Brunner’s criticism of him for his failure to come out as strongly against communism as he had against Nazism:

I cannot admit that it is the duty of Christians or of the Church to give theological backing to what every citizen can, with much shaking of his head, read in his daily paper and what is so admirably expressed by Mr. Truman and by the Pope. Has the ‘East’ of whatever we may call it, really such a hold over us that we must needs oppose it with our last breath when the last but one would suffice? No, when the Church witnesses it moves in fear and trembling, not with the stream but against it.
