Abstract
The recovery of theological integrity effected by Karl Barth has very much to do with his polemic against natural theology. Theology has regained credibility, however, at the price of being made unnatural, severed from the world in its own ecclesiastical sphere. This actually represents an indirect endorsement of natural theology inasmuch as the naturalistic understanding of the world is taken for granted as the way the world is. One result of this is the virtual abandonment of nature for theology, reflected in an alienation from science and a disinterest in ecology. The more specific object of Barth's critique of natural theology, Nazism, may also exert a reverse influence on Barth's theology, helping to account for its Christological exclusivism. The implication of this is that the critique of natural theology requires a renewed appreciation of the naturalness of theology
