The only letter I ever want to address to 'average people' is one that says - I do not care whether you believe in Christianity or not, but I do resent your being so ignorant, lazy, and unintelligent. Why don't you take the trouble to find out what is Christianity and what isn't? Why, when you can bestir yourself to mug up technical terms about electricity, won't you do as much for theology before you begin to argue about it? ... You would be ashamed to know as little about internal combustion as you do about the Nicene Creed.
Quoted in One Eternal Day: Dorothy L. Sayers on doctrinal ignorance
