As usual, CS Lewis has something useful to contribute. From the Screwtape letters:

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 reasons are obvious. In the first place the parochial organisation should always be attacked, because, being a unity of place and not of likings, it brings people of different classes and psychology together in the kind of unity the Enemy desires. The congregational principle, on the other hand, makes each church into a kind of club, and finally, if all goes well, into a coterie or faction. In the second place, the search for a "suitable" church makes the man a critic where the Enemy wants him to be a pupil. What He wants of the layman in church is an attitude which may, indeed, be critical in the sense of rejecting what is false or unhelpful, but which is wholly uncritical in the sense that it does not appraise - does not waste time in thinking about what it rejects, but lays itself open in uncommenting, humble receptivity to any nourishment that is going. (You see how grovelling, how unspiritual, how irredeemably vulgar He is!) This attitude, especially during sermons, creates the condition (most hostile to our whole policy) in which platitudes can become really audible to a human soul. There is hardly any sermon, or any book, which may not be dangerous to us if it is received in this temper. So pray bestir yourself and send this fool the round of the neighbouring churches as soon as possible. Your record up to date has not given us much satisfaction.

I always found the idea of the unity of place rather than of liking especially important.
