Although the wager of battle and the other ordeals have much in common, there is sufficient distinction between them to render convenient their separate consideration, even at the risk of a little occasional repetition. The development and career of these forms of the judgment of God were not in all respects similar, nor was their employment in all cases the same. The mere fact that the duel was necessarily a bilateral ordeal, to which both sides had to submit, in itself establishes a limit as to the cases fitted for its employment, nor were all races of mankind adapted by character for its use. Moreover, in its origin it was simply a device for regulating under conditions of comparative fairness the primitive law of force, and the conception of the intervention of a Divine Power, whereby victory would enure to the right, probably was a belief subsequently engrafted on it. In the other ordeals this is the fundamental idea on which they were based, and we may perhaps assume that they represent a later development in human progress, in which brute strength has declined somewhat from its earliest savage supremacy, and a reliance upon the interposition of a superhuman agency, whether the spirit of a fetish or an omnipotent and just Godhead, single or multiform, has grown sufficiently strong to be a controlling principle in the guidance of daily life. Yet this, too, is only a step in the evolution of human thought, before it can grasp the conception of an Omnipotence that shall work out its destined ends, and yet allow its mortal creatures free scope to mould their own fragmentary portions of the great whole—a Power so infinitely great that its goodness, mercy, and justice are compatible with the existence of evil in the world which it has formed, so that man has full liberty to obey the dictates of his baser passions, without being released from responsibility, and, at the same time, without disturbing the preordained results of Divine wisdom and beneficence. Accordingly, we find in the religious history of almost all races that a belief in a Divine Being is accompanied with the expectation that special manifestations of power will be made on all occasions, and that the interposition of Providence may be had for the asking, whenever man, in the pride of his littleness, condescends to waive his own judgment, and undertakes to test the inscrutable ways of his Creator by the touchstone of his own limited reason. Thus miracles come to be expected as matters of every-day occurrence, and the laws of nature are to be suspended whenever man chooses to tempt his God with the promise of right and the threat of injustice to be committed in His name.
