It is not demonstrably unchristian to kill the rich as violators of definable justice. It is not demonstrably unchristian to crown the rich as convenient rulers of society. It is not certainly unchristian to rebel against the rich or to submit to the rich. But it is quite certainly unchristian to trust the rich, to regard the rich as more morally safe than the poor.
G.K. Chesterton, Orthodoxy, chapter 7: The Eternal Revolution
