Heretics

'Nothing more strangely indicates an enormous and silent evil of modern society than the extraordinary use which is made nowadays of the word 'orthodox.' In former days the heretic was proud of not being a heretic. It was the kingdoms of the world and the police and the judges who were heretics. He was orthodox.' So begins 'Heretics' by Gilbet K. Chesterton. 'Heretics' is a classic piece of religious exposition.
