There is a universal moral law, as distinct from a moral code, which consists of certain statements of fact about the nature of man; and by behaving in conformity with which, man enjoys his true freedom. This is what the Christian Church calls "the natural law." The more closely the moral code agrees with the natural law, the more it makes for freedom in human behavior; the more widely it departs from the natural law, the more it tends to enslave mankind and to produce the catastrophes called "judgments of God."
