My dear Wormwood,
.... You mentioned casually in your last letter that the patient has continued to attend one church, and one only, since he was converted, and that he is not wholly pleased with it.
May I ask what you are about? Why have I no report on the causes of his fidelity to the parish church? Do you realise that unless it is due to indifference it is a very bad thing? Surely you know that if a man can’t be cured of churchgoing, the next best thing is to send him all over the neighbourhood looking for the church that ‘suits’ him until he becomes a taster or connoisseur of churches.... the search for a ‘suitable’ church makes the man a critic where the Enemy wants him to be a pupil....
Your affectionate uncle,
SCREWTAPE
