"[...] the Christian idea of man “made in the image and likeness of God” has created, on a political level, a tension that runs through the entire history of the West. It is, in fact, an ideal which, despite compromising and even murky vicissitudes, between ‘theocratic’ temptations and ‘satanocratic’ rejections of political power, has exerted, throughout history, a sometimes overwhelming pressure on its antithetical worldly element. “Render unto Caesar the things that are Caesar's, and unto God the things that are God's”: with this, the principle that Káysar is not Kýrios entered history – political power was desacralised, the worldly order relativised, and Caesar's demands subjected to a judgement of legitimacy by an inviolable conscience. On this basis, Origen could justify, against Celsus, the refusal of Christians to associate themselves with the cult of the emperor or to refuse to kill in obedience to his orders."
