Man's ideas of course underwent modifications as civilization advanced. The religious idea had taken root and elaborated ramifications, and laws were evolved to govern them. The sun of prosperity shone; communities grew stronger and more numerous; from the worship of the physical laws of nature, the laws governing morality became involved. Thus morals invaded nations, over which they enthroned their gods. Every nation elaborated its own details, and slowly took its relative position. As these gods grew in importance men assumed the responsibility to guard them, and the function to attend them. Thus a class called priests were chosen, elected, or self-appointed to minister to them. These functionaries at the same time assumed the moral and political guidance of nations or communities, and individuals. In this manner arose hundreds upon hundreds of Gods: Io, Isis, Jupiter, Juno, etc., etc. The qualities of the gods, like the qualities of men, were good and bad. They were good and evil, light and dark, life and death, and were arranged to suit the time and occasion. When laws were established to govern society, obedience to these laws was declared to be right, disobedience wrong. Men learned this; they became conscious of what was right and what was wrong. The ministration to these gods was acknowledged to be a righteous act. Rules were established to prevent any violation or infringement of the duty due to these gods. A trespass in violation of anything considered sacred was regarded as an evil--a sin. Slowly the consciousness of sin, of doing wrong, of violating the law, was recognized and established, and the attitude men assumed towards the gods, or their conduct towards them, was regarded as moral holiness, sanctity, or piety. The evolution of images, idols, gods and goddesses, was not the work of a day, but of very many centuries. The same may be said of sacrifices, worship, ceremonies, the laws concerning the same, holiness, sin, good and evil, sanctity, sacrilege, divinity, blasphemy, etc., etc.
