'... Christian teachers in secular schools may, I sometimes think, do more good precisely because they are not allowed to give religious instruction in class. At least I think that, as a child, I shd. have been very allured and impressed by the discovery - which must be made when questions are asked - that the teacher believed firmly in a whole mass of things he wasn't allowed to teach! Let them give us the charm of mystery if they please.'
CS Lewis in Walter Hooper (Ed.), The Collected Letters of CS Lewis Vol III, p.332.
