The function of Parable in religion is to exhibit "form by form." Law undertakes the profounder task of comparing "line by line." Thus Natural Phenomena serve mainly an illustrative function in Religion. Natural Law, on the other hand, could it be traced in the Spiritual World, would have an important scientific value--it would offer Religion a new credential. The effect of the introduction of Law among the scattered Phenomena of Nature has simply been to make Science, to transform knowledge into eternal truth. The same crystallizing touch is needed in Religion. Can it be said that the Phenomena of the Spiritual World are other than scattered? Can we shut our eyes to the fact that the religious opinions of mankind are in a state of flux? And when we regard the uncertainty of current beliefs, the war of creeds, the havoc of inevitable as well as of idle doubt, the reluctant abandonment of early faith by those who would cherish it longer if they could, is it not plain that the one thing thinking men are waiting for is the introduction of Law among the Phenomena of the Spiritual World? When that comes we shall offer to such men a truly scientific theology. And the Reign of Law will transform the whole Spiritual World as it has already transformed the Natural World. I confess that even when in the first dim vision, the organizing hand of Law moved among the unordered truths of my Spiritual World, poor and scantily-furnished as it was, there seemed to come over it the beauty of a transfiguration. The change was as great as from the old chaotic world of Pythagoras to the symmetrical and harmonious universe of Newton. My Spiritual World before was a chaos of facts; my Theology, a Pythagorean system trying to make the best of Phenomena apart from the idea of Law. I make no charge against Theology in general. I speak of my own. And I say that I saw it to be in many essential respects centuries behind every department of Science I knew. It was the one region still unpossessed by Law. I saw then why men of Science distrust Theology; why those who have learned to look upon Law as Authority grow cold to it--it was the Great Exception.
