33. Thus in days gone by arose the oracles of the Greeks, and thus they were led astray by the demons. But thus also thenceforth their deception was brought to an end by the coming of the Lord , who brought to nought the demons and their devices. For they know nothing of themselves, but, like thieves, what they get to know from others they pass on, and guess at rather than foretell things. Therefore if sometimes they speak the truth, let no one marvel at them for this. For experienced physicians also, since they see the same malady in different people, often foretell what it is, making it out by their acquaintance with it. Pilots, too, and farmers, from their familiarity with the weather, tell at a glance the state of the atmosphere, and forecast whether it will be stormy or fine. And no one would say that they do this by inspiration, but from experience and practice. So if the demons sometimes do the same by guesswork, let no one wonder at it or heed them. For what use to the hearers is it to know from them what is going to happen before the time? Or what concern have we to know such things, even if the knowledge be true? For it is not productive of virtue, nor is it any token of goodness. For none of us is judged for what he knows not, and no one is called blessed because he hath learning and knowledge. But each one will be called to judgment in these points -- whether he have kept the faith and truly observed the commandments.'
