Augustine giving advice to a politician on why the political order cannot ignore the supreme good - God.
“If any of your governing, however informed by virtues I listed, is directed only to the final aim of allowing human beings to suffer no unjust hardships in the flesh; and if you think that it is no concern of yours to what purpose they put the peace that you struggle to provide for them (that is, to speak directly, how to worship the true God, with whom the fruit of all peaceful life is found), then all that effort towards the life of true blessedness will not benefit you at all.”
