'I do not mean to suggest that the desire to meet infidelity half-way is the sole or even the main cause responsible for the loose theology of our time. No preacher would deliberately judge the credibility of his message by the credulity of his audience. But the prevalent irreligion of the age does exercise a continual unconscious pressure upon the pulpit; it makes preachers hesitate to affirm doctrines whose affirmation would be unpopular. And a doctrine which has ceased to be affirmed is doomed, like a disused organ, to atrophy.'
Mgr Ronald Knox - 'The Belief of Catholics' (1927)
