...there being a god, that god must be worshiped. Worship means raising the god above the individual, and liturgies often make the point that the individual is less than nothing compared to the deity. If this be done, then, when the god is invoked, the individual has so little worth that he or she may be sacrificed for the needs of the god....
And who speaks for the god? If all people do, then no one does, and there is no god. If the people accept a priesthood, or the equivalent, then those priests exercise whatever power that god's believers grant that god over them, and that elite may cause an individual to be worth less, to be exiled, or even to die or to be killed. Yet such powers do not come from a deity.
In modern history and science, never has there been a verified occasion of a god appearing or demonstrating the powers ascribed throughout history to deities. Always, there is a prophet who speaks for the god. Why cannot the god speak? If a god is omnipotent, then the god can speak. If he cannot, then that god is not omnipotent. Often the prophets say that a god will only speak to the chosen, the worthy.
Should a people accept a god who is either too powerless to speak, or too devious and skeptical to appear? Or a god who will only accept those who swallow a faith laid out by a prophet who merely claims that deity exists—without proof? Yet people have done so, and have granted enormous powers to those who speak for god.
