It appears the time came when, as a matter of self-defense, man must manipulate and control spirits to save himself from destruction, and there were persons particularly adapted to this process, who formed the germs of the great system of priesthood. They stood between the masses and the spirits, and as the system developed and the number of priests increased, they became the ones who ruled the masses in place of the spirits. The priesthood, then, wherever it has developed a great system, has exercised an almost superhuman power over the ignorant, the debased, and the superstitious. It was the policy of kings to cultivate and protect this priesthood, and it was largely this which enabled them to have power over the masses. Having once obtained this power, and the military spirit having arisen in opposition to foreign tribes, the priests were at the head of the military, religious, and civil systems of the nation. Indeed, the early king was the high priest of the tribe, and he inherited through long generations the particular function of leader of religious worship. It will be easy to conceive that where the art of embalming was carried on, people believed in the future life of the soul. The religious system of the Egyptians was, indeed, of very remarkable character. The central idea in their doctrine was the unity of God, whom they recognized as the one Supreme Being, who was given the name of Creator, Eternal Father, to indicate the various characters in which he appeared. This pure monotheism was seldom grasped by the great masses of the people; indeed, it is to be supposed that many of the priestly order scarcely rose to its pure conceptions. But there {173} were other groups or dynasties of gods which were worshipped throughout Egypt. These were mostly mythical beings, who were supposed to perform especial functions in the creation and control of the universe. Among these Osiris and Isis, his wife and sister, were important, and their worship common throughout all Egypt. Osiris came upon the earth in the interests of mankind, to manifest the true and the good in life. He was put to death by the machinations of the evil spirit, was buried and rose, and became afterward the judge of the dead. In this we find the greatest mystery in the Egyptian religion. Typhon was the god of the evil spirits, a wicked, rebellious devil, who held in his grasp all the terrors of disease and of the desert. Sometimes he was in the form of a frightful serpent, again in the form of a crocodile or hippopotamus.
