Christianity brought about a revolution in European civilisations and is now part of the political and moral DNA of the West. But the Church was also party to unholy alliances with Western rulers, not least in its complicity with European empires that wrought colonial violence all over the world. Yet whatever the good, bad and ugly of history, the Church cannot retreat from politics. If we are to speak truth to power and stand up to the powers, then we must do kingdom-business with the business of political power (chapter 2).
