22 The last and most important point remains, whether, O Emperors, you ought to restore those helps which have profited you; for he says: 'Let them defend you, and be worshipped by us.' This it is, most faithful princes, which we cannot endure, that they should taunt us that they supplicate their gods in your names, and without your commands, commit an immense sacrilege, interpreting your shutting your eyes as consent. Let them have their guardians to themselves, let these, if they can, protect their worshippers. For, if they are not able to help those by whom they are worshipped, how can they protect you by whom they are not worshipped?
