The City of God, Volume I

20. Whether we are to believe that the good gods are more willing to have intercourse with demons than with men.

But does any urgent and most pressing cause compel the demons to mediate between the gods and men, that they may offer the prayers of men, and bring back the answers from the gods? and if so, what, pray, is that cause, what is that so great necessity? Because, say they, no god has intercourse with man. Most admirable holiness of God, which has no intercourse with a supplicating man, and yet has intercourse with an arrogant demon! which has no intercourse with a penitent man, and yet has intercourse with a deceiving demon! which has no intercourse with a man fleeing for refuge to the divine nature, and yet has intercourse with a demon feigning divinity! which has no intercourse with a man seeking pardon, and yet has intercourse with a demon persuading to wickedness! which has no intercourse with a man expelling the poets by means of philosophical writings from a well-regulated state, and yet has intercourse with a demon requesting from the princes and priests of a state the theatrical performance of the mockeries of the poets! which has no intercourse with the man who prohibits the ascribing of crime to the gods, and yet has intercourse with a demon who takes delight in the fictitious representation of their crimes! which has no intercourse with a man punishing the crimes of the magicians by just laws, and yet has intercourse with a demon teaching and practising magical arts! which has no intercourse with a man shunning the imitation of a demon, and yet has intercourse with a demon lying in wait for the deception of a man!

21. Whether the gods use the demons as messengers and interpreters, and whether they are deceived by them willingly, or without their own knowledge.
