Adversus haereses

² But if some had been made by nature bad, and others good, these latter would not be deserving of praise for being good, for such were they created; nor would the former be reprehensible, for thus they were made [originally]. But since all men are of the same nature, able both to hold fast and to do what is good; and, on the other hand, having also the power to cast it from them and not to do it—some do justly receive praise even among men who are under the control of good laws (and much more from God), and obtain deserved testimony of their choice of good in general, and of persevering therein; but the others are blamed, and receive a just condemnation, because of their rejection of what is fair and good. And therefore the prophets used to exhort men to what was good, to act justly and to work righteousness, as I have so largely demonstrated, because it is in our power so to do, and because by excessive negligence we might become forgetful, and thus stand in need of that good counsel which the good God has given us to know by means of the prophets.
