De Virtutibus

For it is a very excellent and expedient thing to go over to virtue without ever looking back again, forsaking that treacherous mistress, vice. And at the same time it is necessary that, as in the sun shadow follows the body, so also a participation in all other virtues must inevitably follow the giving due honour to the living God;

for those who come over to this worship become at once prudent, and temperate, and modest, and gentle, and merciful, and humane, and venerable, and just, and magnanimous, and lovers of truth, and superior to all considerations of money or pleasure; just as, on the contrary, one may see that those who forsake the holy laws of God are intemperate, shameless, unjust, disreputable, weak-minded, quarrelsome, companions of falsehood and perjury, willing to sell their liberty for luxurious eating, for strong wine, for sweetmeats, and for beauty, for pleasures of the belly and of the parts below the belly; the miserable end of all which enjoyments is ruin to both body and soul.

Moreover, Moses delivers to us very beautiful exhortations to repentance, by which he teaches us to alter our way of life, changing from an irregular and disorderly course into a better line of conduct; for he says that this task is not one of any excessive difficulty, nor one removed far out of our reach, being neither above us in the air nor on the extreme borders of the sea, so that we are unable to take hold of it; but it is near us, abiding, in fact, in three portions of us, namely, in our mouths, and our hearts, and our hands; [*]( Deuteronomy xxx. 11. ) by symbols, that is to say, in our words, and counsels, and actions; for the mouth is the symbol of speech, and the heart of counsels, and the hands of actions, and in these happiness consists.
