For him, philosophy was man’s search for truth apart from God. It was a type of Barth’s “religion,” in which man himself tried to reach heaven or truth or God. But theology begins and ends with faith in Christ, who reveals himself to man; apart from such revelation, there could be no such thing as truth. Thus the philosopher—and the theologian who operates on a philosopher’s assumptions—chases his own tail and gazes at his own navel. He cannot break out of that cycle, but God, via revelation, can break in.
