a veritable hotbed

Been rereading Screwtape. Found this to be really delightful.

I think I warned you before that if your patient can't be kept out of the Church, he ought at least to be violently attached to some party within it. I don't mean on really doctrinal issues; about those, the more lukewarm he is the better. And it isn't the doctrines on which we chiefly depend for producing malice. The real fun is working up hatred between those who say 'mass' and those who say 'holy communion' when neither party could possibly state the difference between, say, Hooker's doctrine and Thomas Aquinas', in any form which would hold water for five minutes. And all the purely indifferent things--candles and clothes and what not--are an admirable ground for our activities. We have quite removed from men's minds what that pestilent fellow Paul used to teach about food and other unessentials--namely, that the human without scruples should always give in to the human with scruples. You would expect to find the 'low' churchman genuflecting and crossing himself lest the weak conscience of his 'high' brother should be moved to irreverence, and the 'high' one refraining from these exercises lest he should betray his 'low' brother into idolatry. And so it would have been but for our ceaseless labour. Without that the variety of usage within the Church of England might have become a positive hotbed of charity and humility,
