We find this institution in the course of time and in various countries debased by polygamy, and corrupted by concubinage. These aberrations testify to the force of human passion, and the wantonness of power and wealth ever warring against it, but they only enhance thereby the force of the institution's universal existence from the point of view from which I have regarded it. 2. Take, secondly, the rite of bloody sacrifice. It would be hard to find anything more contrary to reason and feeling than the thought that taking away the life of innocent creatures by pouring out their blood could be not only acceptable to the Maker of those creatures, but could be accepted by Him in expiation of sin committed by man. Yet this is the conception of bloody sacrifice; this was expressed in the rites which accompanied it; and besides this particular notion of expiation, which is the correlative of sin, the most solemn duties of man, that is, Adoration, Thanksgiving, and Petition, the whole expression of his obedience to God, and dependence on God, were bound up with this rite, and formed part of it. And we find this rite of sacrifice existing from the earliest times in these various nations; continued through the whole of their history, solemnised at first by their kings and chief men, and then by an order of men created for that special purpose, and in every nation themselves holding a high rank in virtue of their performing this function. What, again, are the chances of a rite so peculiar being chosen spontaneously by so many various nations, and chosen precisely to express their homage for their own creation and continuance in being, to make their prayers acceptable, and above all, to cover their sin, to serve as an expiation, and to turn away punishment. This is the testimony which Assyria and Egypt, which Greece and Rome, which India and China bear to their original unity. If God instituted this rite, at the fall itself, as a record and token of the promise then made, its existence through the many changes of the race becomes intelligible; on any other supposition it remains a contradiction both to reason and feeling, which is like nothing else in human history. The institution of sacrifice comprehends with its accompaniments the whole of religion. It suffered the most grievous corruption in that it was offered to false gods, to deified men, to powers of nature, to those who were not gods but demons. Again, its meaning was obscured, and the priests who offered it were not pure in their lives. But whatever abominations were at any time or in any place connected with it, its peculiarity, its testimony to the unity of the race, to the power which established it, remain without diminution.
