...most of the [first martyrs] died....for refusing to extend a civil loyalty into a religious idolatry. Most of them did not die for refusing to worship Mercury or Venus, or fabulous figures who might be supposed not to exist; or others like Moloch or Priapus whom we might well hope do not exist. Most of them died for refusing to worship somebody who certainly did exist; and even somebody whom they were quite prepared to obey but not to worship. The typical martyrdom generally turned on the business of burning incense before the statue of Divus Augustus; the sacred image of the Emperor. He was not necessarily a demon to be destroyed; he was simply a despot who must not be turned into a deity. That is where their case came so...very near to the practical problem of mere State-worship to-day. And it is typical of all Catholic thought that men died in torments, not because their foes "spoke all false"; but simply because they would not give an unreasonable reverence where they were perfectly prepared to give a reasonable respect. For us the problem of Progress is always a problem of Proportion: improvement is reaching a right proportion, not merely moving in one direction. And our doubts about most modern developments, about the Socialists in the last generation, or the Fascists in this generation, do not arise from our having any doubts at all about the desirability of economic justice, or of national order...[but of the] Divine Right of Kings.
