I think religion and the state server each other. Every religion opposes government only when there is no agreement between them. Christianity opposed rulers till they did not let the church to lay its own authority and when the rulers became 'devoted' christian, they helped each other against the common man, peasants, surfs etc. I think Jesus was the real revolutionary, likewise Buddha, who were against the atrocities and crimes committed by the state and the contemporary prevailing religion against the commoners. But his so called followers (priests, church) used his name and ideas (contorted), for their own benefit. This is the reality of humanity.
