It's just because I have picked a little about mystics that I have no use for mystagogues. Real mystics don't hide mysteries, they reveal them. They set a thing up in broad daylight, and when you've seen it it's still a mystery. But the mystagogues hide a thing in darkness and secrecy, and when you find it, it's a platitude.
If you try to talk about a truth that’s merely moral, people always think it’s merely metaphorical. A real live man with two legs once said to me: ‘I only believe in the Holy Ghost in a spiritual sense.’ Naturally, I said: ‘In what other sense could you believe it?’ And then he thought I meant he needn’t believe in anything except evolution, or ethical fellowship, or some bilge. . . . -- The Secret of Father Brown
