It is sometimes claimed that “natural law” theory is inherently Christian. This simply is not correct, though it is true that Christians, especially Thomistic Catholics, later adopted some aspect of natural law theory. In his work, Natural Law, A.P. d’Entréves said that: “The Thomistic interpretation of Christianity is unthinkable without the notion of natural law.” But natural law originated in Greek culture. According to d’Entréves, the theologian E. Troeltsch, wrote that natural law was “an alien element in Christianity” and represented “the inheritance of the ancient world which could be adapted to Christian teaching.”
Prof. Paul Conkin, in Self-Evident Truths, writes: “Natural-law theories originated in Greek philosophy. Plato and Aristotle affirmed not only a formal logical order in the world but an inherent purposefulness in all things. Nature stood for both the order and the purpose. Aristotle’s universe was one vast congeries of yearnings, of informed objects moving toward their own perfection and, in a sense, trying to imitate the objects above them in a chain of being stretching to a perfect mind which pulls all things toward it. Man, by his intellect, can grasp the formal truth in objects, can understand the structure of the universe. More importantly he can understand himself, grasp his own nature, which is also to perceive his own highest good.”
