Amanda Power at Lapham's Quarterly:
At its most essential level, the notion of an omniscient, omnipotent, interested, judging God was translated into our inherited forms of governance through the Roman Catholic interpretation of Christ’s words to Peter, in the Gospel According to Matthew. “Upon this rock I will build my church,” Christ says to his apostle, “and the gates of Hades shall not overpower it. I will give you the keys of the kingdom of heaven; and whatever you shall bind on earth shall be bound in heaven, and whatever you shall loose on earth shall be loosed in heaven.” The Church alleged that this authority had been transmitted through the succession of the bishops of Rome, and flowed from pope on down through the clerical hierarchy, so that every priest shared in the power to bind and loose on earth, in the knowledge that their decisions would be upheld by God.
Through the priests, God’s power to watch and judge had a human embodiment. They were not to shed blood, but there were circumstances in which they were to hand over obdurate individuals to secular authorities for execution. God’s dispersed authority was thus delegated even to laypeople whose individual jurisdiction extended no further than towns and villages. At the top of the secular hierarchy, monarchs were anointed by priests, thus symbolizing their religious legitimacy. As in John of Salisbury’s “ministers of God,” these monarchs’ worst abuses were sanctioned by the assertion of the elites that governments always operated with the backing of watchful divine will.
