It is the decided opinion of all who use their brains, that all men desire to be happy. But who are happy, or how they become so, these are questions about which the weakness of human understanding stirs endless and angry controversies, in which philosophers have wasted their strength and expended their leisure. To adduce and discuss their various opinions would be tedious, and is unnecessary. The reader may remember what we said in the eighth book, while making a selection of the philosophers with whom we might discuss the question regarding the future life of happiness, whether we can reach it by paying divine honors to the one true God, the Creator of all gods, or by worshipping many gods, and he will not expect us to repeat here the same argument, especially as, even if he has forgotten it, he may refresh his memory by reperusal. For we made selection of the Platonists, justly esteemed the noblest of the philosophers, because they had the wit to perceive that the human soul, immortal and rational, or intellectual, as it is, cannot be happy except by partaking of the light of that God by whom both itself and the
world were made; and also that the happy life which all men desire cannot be reached by any who does not cleave with a pure and holy love to that one supreme good, the unchangeable God. But as even these philosophers, whether accommodating to the folly and ignorance of the people, or, as the apostle says, “becoming vain in their imaginations,” supposed or allowed others to suppose that many gods should be worshipped, so that some of them considered that divine honor by worship and sacrifice should be rendered even to the demons (an error I have already exploded), we must now, by God’s help, ascertain what is thought about our religious worship and piety by those immortal and blessed spirits, who dwell in the heavenly places among dominations, principalities, powers, whom the Platonists call gods, and some either good demons, or, like us, angels,–that is to say, to put it more plainly, whether the angels desire us to offer sacrifice and worship, and to consecrate our possessions and ourselves, to them or only to God, theirs and ours.
