Now we charge them that are such, and beseech them by the Lord Jesus Christ, that, working with silence, they would eat their own bread.

“This we must also keep in mind—that he who labors ought to perform his task not for the purpose of ministering to his own needs but that he may accomplish the Lord's command, "I was hungry and you gave me to eat," and so on. To be concerned for oneself is strictly forbidden by the Lord in the words, "Be not concerned for your life, what you shall eat, nor for your body, what you shall put on," and he adds, "for the heathens seek after all these things." Everyone, therefore, in doing his work, should place before himself the aim of service to the needy and not his own satisfaction. Thus, he will escape the charge of self-love and receive the blessing for fraternal charity from the Lord, who said, "As long as you did it to one of these, the least of my brothers, you did it to me." Nor should anyone think that the apostle is at variance with our rule when he says, "that working they would eat their own bread." This is addressed to the unruly and indolent, and means that it is better for each person to minister to himself at least and not be a burden to others than to live in idleness.”

“"For we hear of some that walk among you disorderly, that work not at all, but are busybodies." This indeed he says here; but there, in the first Epistle, he says, "that ye may walk honestly towards them that are without." On what account? Perhaps there was as yet no such thing. For upon another occasion also admonishing, he says, "It is more blessed to give than to receive." But the expression, "walk honestly" has no reference to disorder; wherefore he added, "that ye may have need of nothing." And here he sets down another necessity, for thus doing what was honorable and good towards all. (For as he proceeds, he says, "be not weary in well doing.") For certainly he that is idle and yet able to work must needs be a busybody. But alms are given to those only who are not able to support themselves by the work of their own hands, or who teach, and are wholly occupied in the business of teaching. "For thou shalt not muzzle the ox," he says, "when he treadeth out the corn." "And the laborer is worthy of his hire." So that neither is he idle, but receives the reward of work and great work too. But to pray and fast being idle, is not the work of the hands. For the work that he is here speaking of is the work of the hands. "That work not at all, but are busybodies. Now them that are such we command and exhort through our Lord Jesus Christ." Because he had touched them severely, wishing to render his discourse more mild, he adds, "through the Lord," again what is authoritative and fearful. "That with quietness," he says, "they work, and eat their own bread." For why has he not said, But if they are not disorderly let them be maintained by you; but requires both, that they be quiet, and that they work? "That they may eat their own bread," says he, not that of another.”

“Above, the Apostle showed what he handed on to them by his own example, namely that they should not be restless, but that they should work; here he shows how he handed this on in the present passage by words and by deeds. Hence he says *when we were*, as if to say: that we might give you a model, we did what we taught, because we declared this, that, etc. These words, as the Gloss says, and Augustine in the book *On the Works of Monks*, certain men were perverting, to mean that it is not lawful for the servants of God to work with their hands, on account of what is said in Matthew 6:34: *be not solicitous*, etc. For they say that this work pertains to solicitude for sustenance. And on account of this they referred this to spiritual works; as if to say: if anyone does not want to do meritorious and spiritual works, he is not worthy to eat. But this is against the intention of the Apostle, who says *we declared* that we ourselves did so, namely in labor and weariness. But what is the meaning of *because if anyone does not want*, etc.? Is this a counsel or a precept? And it seems to be a precept, because below it is said: *if anyone does not obey our word*, etc. Therefore all are bound to work with their hands. Whoever therefore does not work with his hands, but stands idle, sins mortally. I answer. It must be said that it is a precept, but a thing is commanded in two ways: simply, or under a condition. That which is of itself necessary for salvation is commanded simply, and these are the works of the virtues. But under a condition, as when such is the case that the precept cannot be kept without manual work. Now it is commanded to man that he sustain his own body, for otherwise he is a murderer of himself. Genesis 2:16: *of every tree of Paradise you may eat*, etc. By precept, therefore, man is bound to nourish his own body, and likewise we are bound to all the things without which the body cannot live. Hence whoever does not have another means by which to sustain his body lawfully, either by possession or by lawful business, is bound to labor, lest he steal. Ephesians 4:28: *he who stole, let him now steal no more, but rather let him labor, working with his hands*, etc. It is therefore a precept, when one cannot otherwise live lawfully. Hence he says *if anyone does not want to work, neither let him eat*. One or the other of two things is therefore necessary, that a man may eat, namely either that he have a possession, or that he procure it lawfully. Psalm 127:2: *the labors of your hands, for you shall eat*, etc. 1 Thessalonians 4:11: *work with your hands, as we commanded you*, etc. Then when he says *we have heard*, etc., he sets forth the necessity of this precept, because the Apostle says this not so much from the office of a teacher, as on account of a vice of the people. Therefore first he sets forth the fault which induces the necessity of the precept; second he applies a remedy, at the place *but to those who*, etc. He says therefore *we have heard*, etc.; as if to say: therefore I do not conceal this precept, because we have heard that certain ones, etc. For the soul of man must always be occupied about something, and therefore it is necessary that the idle suffer restlessness about unlawful things. 1 Thessalonians 4:11: *give heed that you be quiet*, etc. And he adds *but acting curiously*, namely about the affairs of others. Proverbs 21:25: *desires kill the slothful*. Then he applies a remedy, when he says *but to those who*, etc. And first on the part of those sinning, second on the part of the others, at the place *but you*, etc. He says therefore, to those who are of this sort *we declare* — severely, as a prelate — and *we beseech* — charitably, as their father — that their own bread, not another's but owed to them, namely lawfully acquired, *with silence*, that is, without restlessness, not running about, they eat. Isaiah 30: the cultivation of justice is silence. Ezekiel: idleness taught much malice. Then when he says *but you*, etc., on the part of the others not sinning he applies a twofold remedy. First, namely, that they not cease from doing good; second, that they correct those men, at the place *but if anyone*, etc. He says therefore *but you*, etc., as if to say: do not fail in doing good, even though the idle abuse it. Galatians 5: *doing good, let us not fail*, etc. And this is necessary, even if they should work with their hands, and nothing should be lacking to them, because assistance to others is necessary. Then when he says *but if anyone*, etc., he signifies that they be corrected, and first he shows in what order they are punished; second he shows the effect of the punishment, at the place *that they may be ashamed*; third the end, at the place *and do not*, etc. As to the order indeed: first, he sets forth the fault, second its manifestation, third its punishment. The fault is disobedience; and therefore he says *but if anyone does not obey*. 1 Kings 15:23: *to resist is as it were the sin of divination, and to be unwilling to acquiesce is as it were the crime of idolatry*. The manifestation and the conviction is set forth, when he says *note this man by an epistle*, that is, make him manifest, but through an inquiry into the truth. Job 29:16: *the cause which I did not know, I investigated most diligently*. Their punishment is the sentence of excommunication; hence he says *and do not mingle with him*, etc. 1 Corinthians 5:11: *with such a one not even to take food*. 2 John, v. 10: *do not receive him into the house, nor say to him, hail*. Here note that excommunication is inflicted for disobedience; he must, however, be convicted. Hence he says *if anyone does not obey*, by your epistle, *note this man*, that is, signify him to us, that he may be punished; and yet you meanwhile are not to mingle with him. But the effect of the punishment is that he be ashamed, and from this come to his senses. Ecclesiasticus 4:25: *there is a shame that brings sin, and there is a shame that brings glory*. But the end and intention ought to be his correction, which charity intends; hence he says *and do not regard him as*, because it ought not to be done out of the rancor of hatred, but out of zeal for charity; as if to say: let your avoiding of him not be done out of the hatred of enmity. Matthew 5:44: *love your enemies, do good to those who hate you*. And therefore he says *but correct him as a brother*. In which charity is shown. Psalm 132:1: *behold how good, and how pleasant it is for brothers to dwell in one*, etc. Then when he says *but he himself*, etc., he concludes the epistle. And first the conclusion is set forth; second the salutation, which is as it were the seal of the epistle, at the place *the salutation*, etc. Again the first is divided into two, because he first wishes them the gifts of God, second God himself, at the place *the Lord be*, etc. As to the first he says *he himself*, etc. God is said to be of peace with respect to two things. For peace consists in two things, namely that a man be in concord with himself, and with others. And neither can be had sufficiently except in God: because he is not in concord with himself sufficiently except in God, and less so with others, because then the affection of man is in concord within itself when that which is desired according to one thing suffices with respect to all, which nothing can be except God. Psalm 102:5: *who fills your desire with good things*. For whatever other things, besides God, do not suffice for all, but God suffices. John 16:33: *in me you shall have peace*, etc. Likewise men are not united among themselves, except in that which is common among them, and this is above all God. And therefore he says *may the God of peace give* — not a temporal peace, but an everlasting one, that is, a spiritual one, which begins here, and is perfected there. Psalm 147:3: *who has placed peace as your borders*, etc. And this *in every place*, and in the whole world among the faithful. As to the second he says *the Lord be with you all*, because nothing else is well possessed, unless he himself be possessed through faith and charity. *My salutation*, he says this on account of unfaithful men perverting his epistles. Galatians, last chapter: *see with what letters I have written to you with my own hand*, etc. *Which is a sign*, etc. *Grace*, that is, the gratuitous gift of God, which renders you pleasing to God, etc. John 1:17: *grace and truth came through Jesus Christ*.”

“Now them that are such,.... For this was not the case and character of them all. Did such practices generally obtain, no community, civil or religious, could subsist. And the apostle wisely distinguishes them from others, that the innocent might not be involved in the charge. We command and exhort by our Lord Jesus Christ; using both authority and entreaty; taking every way to reclaim them, commanding in the name of Christ and beseeching for the sake of Christ that with quietness they work: with their own hands, at their proper callings, and so support themselves, provide for their families, and have something to give to them that are in need; by which means they will live peaceable and quiet lives, in godliness and honesty, and not disturb the peace of neighbourhoods, churches, and families: and eat their own bread; got by their own labour, and bought with their money, and not the bread of others, or that of idleness.”

“With quietness they work - Μετα ἡσυχιας· With silence; leaving their tale-bearing and officious intermeddling. Less noise and more work! That - they work, and eat their own bread - Their own bread, because earned by their own honest industry. What a degrading thing to live on the bounty or mercy of another, while a man is able to acquire his own livelihood! He who can submit to this has lost the spirit of independence; and has in him a beggar's heart, and is capable of nothing but base and beggarly actions. Witness the great mass of the people of England, who by their dependence on the poor rates are, from being laborious, independent, and respect able, become idle, profligate, and knavish; the propagators and perpetrators of crime; a discredit to the nation, and a curse to society. The apostle's command is a cure for such; and the Church of God should discountenance such, and disown them.”

“by--The oldest manuscripts read, "IN the Lord Jesus." So the Greek, Th1 4:1, implying the sphere wherein such conduct is appropriate and consistent. "We exhort you thus, as ministers IN Christ, exhorting our people IN Christ." with quietness--quiet industry; laying aside restless, bustling, intermeddling officiousness (Th2 3:11). their own--bread earned by themselves, not another's bread (Th2 3:8).”
