Let us then not be listless; for so we shall be able to recover the Greeks also from their error. But when we are in words lovers of wisdom, but in deeds behave unseemly, with what looks shall we face them? With what lips shall we discourse concerning doctrines? For he will say to each of us, How can you that have failed in what is less, claim to teach me about what is greater? You who as yet have not learned that covetousness is a vice, how can you be wise upon the things in heaven?
But do you know that it is a vice? Then, the charge is the greater, because you transgress knowingly. And why speak I of the Greek, for even our laws allow us not to speak thus boldly when our life has become abandoned. For to “the sinner,” it says, “says God, what have you to do to declare my statutes?” There was a time when the Jews were carried away captive, and when the Persians were urgent with them, and called upon them to sing those divine songs unto them, they said, “How shall we sing the Lord's song in a strange land?” Now if it were un lawful to sing the oracles of God in a strange land, much less might the estranged soul do it.
For estranged the merciless soul is. If the Law made those who were captives and had become slaves to men in a strange land, to sit in silence; much more is it right for those who are slaves to sin and are in an alien community (πολιτεί& 139·) to have a curb upon their mouths. And however they had their instruments then. For it says, “Upon the willows in the midst thereof did we hang our instruments,” but still they might not sing. And so we also, though we have a mouth and tongue, which are instruments of speech, have no right to speak boldly, so long as we be slaves to what is more tyrannical than any barbarian, sin.
For tell me what have you to say to the Greek, if you plunder, and be covetous? will you say, Forsake idolatry, acknowledge God, and draw not near to gold and silver? Will he not then make a jest of you, and say, Talk to yourself first in this way? For it is not the same thing for a Gentile to practise idolatry, and a Christian to commit this same (4 manuscripts. om. “same”) sin. For how are we to draw others away from that idolatry if we draw not ourselves away from this? For we are nearer related to ourselves than our neighbor is, and so when we persuade not ourselves, how are we to persuade others?
For if he that does not rule well over his own house, will not take care of the Church either, how shall he that does not rule even over his own soul be able to set others right? Now do not tell me, that you do not worship an image of gold, but make this clear to me, that you do not do those things which gold bids you. For there be different kinds of idolatry, and one holds mammon lord, and another his belly his god, and a third some other most baneful lust. But, “you do not sacrifice oxen to them as the Gentiles do.”
Nay, but what is far worse, you butcher your own soul. But “you do not bow the knee and worship.” Nay, but with greater obedience you do all that they command you, whether it be your belly, or money, or the tyranny of lust. For this is just what makes Gentiles disgusting, that they made gods of our passions; calling lust Venus, and anger Mars, and drunkenness Bacchus. If then you do not grave images as did they, yet do you with great eagerness bow under the very same passions, when you make the members of Christ members of an harlot, and plunge yourself into the other deeds of iniquity. I therefore exhort you to lay to heart the exceeding unseemliness hereof, and to flee from idolatry:— for so does Paul name covetousness— and to flee not only covetousness in money, but that in evil desire, and that in clothing, and that in food, and that in everything else: since the punishment we shall have to suffer if we obey not God's laws is much severer.
For, He says, “the servant that knew his Lord's will,” and did it not, “shall be beaten with many stripes.” With a view then to escaping from this punishment, and being useful both to others and to ourselves, let us drive out all iniquity from our soul and choose virtue. For so shall we attain to the blessings which are to come, whereto may it be granted us all to attain by the grace and love toward man, etc.
