“Where, then, do you show that they renewed the command to flee from city to city? In fact, it was utterly impossible that they should have laid down anything so utterly opposed to their own examples as a command to flee, while it was just from bonds, or the islands in which, for confessing, not fleeing from the Christian name, they were confined, they wrote their letters to the Churches. Paul bids us support the weak, but most certainly it is not when they flee.”

“If we are to hate ungodly and lawless men, we shall go on also to hate sinners. Thus, in regular succession, you will find yourself cut off from most of your brothers, indeed, from all of them. There is not one of them without sin. If it is our duty to hate the enemies of God, we would have to hate not only the ungodly but backsliders as well. Then we would be worse than wild beasts, shunning all and puffed up with pride, just like the Pharisee. Paul commanded us differently. "Admonish the disorderly, encourage the faint-hearted, support the weak, be long-suffering toward all."”

“"And we exhort you, brethren, admonish the disorderly, encourage the faint-hearted, support the weak, be long suffering toward all." Here he addresses those who have rule. Admonish, he says, "the disorderly," not of imperiousness, he says, nor of self-will rebuke them, but with admonition. "Encourage the fainthearted, support the weak, be longsuffering toward all." For he who is rebuked with harshness, despairing of himself, becomes more bold in contempt. On this account it is necessary by admonition to render the medicine sweet. But who are the disorderly? All those who do what is contrary to the will of God. For this order of the Church is more harmonious than the order of an army; so that the reviler is disorderly, the drunkard is disorderly, and the covetous, and all who sin; for they walk not orderly in their rank, but out of the line, wherefore also they are overthrown. But there is also another kind of evils, not such as this indeed, but itself also a vice, little mindedness. For this is destructive equally with sloth. He who cannot bear an insult is feeble-minded. He who cannot endure trial is feeble-minded. This is he who is sown upon the rock. There is also another sort, that of weakness. "Support the weak," he says; now weakness occurs in regard to faith. But observe how he does not permit them to be despised. And elsewhere also in his Epistles he says, "Them that are weak in the faith receive ye." (Rom. xiv. 1) For in our bodies too we do not suffer the weak member to perish. "Be longsuffering toward all," he says. Even toward the disorderly? Yes, certainly. For there is no medicine equal to this, especially for the teacher, none so suitable to those who are under rule. It can quite shame and put out of countenance him that is fiercer and more shameless than all men.”

“Of course, even good men can be sick, suffering from that disobedience which is the penalty of a primal disobedience which, therefore, is a wound or weakness in a nature that is good in itself. It is because of this wound that the good who are growing in grace and living by faith during their pilgrimage on earth are given the counsels, "Bear one another's burdens, and so you will fulfill the law of Christ," and elsewhere, "We exhort you, brothers, reprove the irregular, comfort the fainthearted, support the weak, be patient toward all men. See that no one renders evil for evil to any man." … It is in this way that citizens of the City of God are given medicine during their pilgrimage on earth while praying for the peace of their heavenly fatherland. And, of course, the Holy Spirit is operative internally to give healing power to the medicine which is applied externally, for, otherwise, no preaching of the truth is of any avail. Even though God makes use of one of his obedient creatures, as when he speaks in human guise to our ears—whether to the ears of the body or to the kind of ears we have in sleep—it is only by his interior grace that he moves and rules our mind.”

“Hence, as far as concerns us, who are not able to distinguish those who are predestinated from those who are not, we ought on this very account to will all humanity to be saved. Severe rebuke should be medicinally applied to all by us that they neither themselves perish nor may be the means of destroying others. It belongs to God, however, to make that rebuke useful to them whom he himself has foreknown and predestinated to be conformed to the image of his Son. We do not abstain from admonishing for fear lest by rebuke a person should perish. So why do we not also rebuke for fear that one should rather perish by our withholding admonition? For there is no greater act of compassion on our part than when the blessed apostle says, "Rebuke those that are unruly; comfort the feeble-minded; support the weak; be patient toward all men. See that none render evil for evil."”

“Above he showed how subjects ought to conduct themselves toward their prelates; here he shows the converse. And concerning this he does two things: first he teaches how prelates ought to conduct themselves toward subject priests; second, generally, how they ought to conduct themselves toward all, at the place "see that no one." But it should be known that the care of prelates ought to tend to two things, namely to drawing others back from sins, and to guarding themselves. As to the first, the Apostle says three things. For subjects can suffer defect in three ways: first in act, second in will, third in power. In act, when they burst forth into an act of sin, and then they are to be corrected. And although this holds for every sin, yet they are especially to be corrected concerning the sin of restlessness. And therefore he says "rebuke the unruly." 2 Thess. 3:7: "we were not unruly among you." Ecclesiasticus 19:17: "rebuke your neighbor before you threaten, and give place to fear." In will, when one does not undertake great things, because he is cast down on account of adversities and preceding sins. Hence he says "comfort the fainthearted." The fainthearted is one not having courage for great things, fearing lest he fail. Isaiah 35:4: "say to the fainthearted: take courage and do not fear." Job 4:4: "your hands have strengthened the wavering," etc. In power, when they either sin from weakness, or are weakened in a good act, and these are to be cherished. Hence he says "support," namely by cherishing in the bowels of charity, "the weak," whose power is feeble, either for resisting evils or for doing good. Romans 15:1: "we who are stronger ought to bear the weaknesses of the weak." But the prelate ought to guard himself from defect of whatever kind, and especially from impatience, because he himself carries the whole weight of the multitude. Numbers 11:14: "I cannot alone bear this whole multitude, because it is heavy for me," etc. And therefore he says "be patient toward all." Proverbs 19:11: "the teaching of a man is known through patience." Ps. 91:15: "they will be well patient, that they may proclaim." Then when he says "see that no one," he shows generally how they should conduct themselves toward all. And concerning this he does two things: first he shows how all ought to conduct themselves in certain matters; second, what in all matters, at "but all things." Concerning the first he does three things: first he shows how they ought to conduct themselves toward the neighbor; second, how they should conduct themselves in the things that pertain to God, at "rejoice always"; third, how they should conduct themselves toward his gifts, at "do not [quench] the spirit." As to the neighbor, they ought to conduct themselves so as not to inflict evils on him, and so as to strive to do him good. Hence he says: I said above in particular, but now I say in general, let no one... evil, etc. Ps.: "if I have returned evils to those who repaid me." But on the contrary: vengeance is often sought before a judge. I respond. Just as a moral act is taken according to the intention of the end, so the intention toward two things can be: either toward the evil of that person, such that it rests there, and this is unlawful, because it comes from the rancor of vengeance; or toward the good of correction, or of justice and the preservation of the commonwealth, and thus he does not render evil for evil, but good, namely his correction. As to the second he says "but always what is good," etc. And he says "pursue," not "do": because you ought to take from yourself the occasion of doing good to your neighbor, and not wait for him to give you the occasion of doing good to him. Hence Ps. 33:15: "seek peace, and pursue it." Romans 12:21: "do not be conquered by evil," namely so that you are drawn by it to do evil, "but conquer evil with good," by drawing it back to good. Gal., last chapter: "while we have time, let us do good to all." Then when he says "rejoice always," he shows how they ought to conduct themselves with regard to God, toward whom three things must be had. First, to rejoice in him; hence he says "rejoice always," namely in God, because whatever evil may occur is incomparable to the good, which is God. And therefore let no evil interrupt that; hence he says "rejoice always." Second, "pray" for benefits to be received, at "pray without ceasing." Luke 18:1: "one must always pray, and never fail." But how can this be? I respond. It must be said that this can be in three ways. First, that he always prays who does not omit the appointed hours. A similar thing is found in 2 Kings 9:7: "you shall eat bread at my table always." Second, thus: "always," that is, "pray continually," but then prayer is taken for the effect of prayer. For prayer is the interpretation or unfolding of desire, because when I desire something, then I seek it by praying. Hence prayer is also a petition for fitting things from God, and therefore desire has the force of prayer. Ps. 9:38: "the Lord has heard the desire of the poor." All things therefore that we do proceed from desire. Therefore prayer remains virtually in the good things we do, because the good things we do proceed from good desire. The Gloss: "he does not cease to pray, who does not cease to do good." Third, as to the cause of prayer, namely by giving alms. In the Lives of the Fathers: "he always prays who gives alms, because he who has received alms prays for you, even while you sleep." Likewise, third, to pray for benefits to be received and to give thanks for those received; therefore he says "in all things," namely in good things and in adverse things, "give thanks." Romans 8:28: "for those who love God, all things work together unto good." Colossians 2:7: "abounding in him in thanksgiving." Philippians 4:6: "with thanksgiving. For this is the will," etc. 1 Timothy 2:4: "who wills all men to be saved, and to come to the knowledge of the truth." Then when he says "do not [quench] the spirit," etc., he shows how they should conduct themselves toward the gifts of God. And first, that they not impede them; second, that they not despise them, at "prophecies." Now the Holy Spirit is a divine person, incorruptible and eternal, hence in his substance he cannot be extinguished. But nevertheless someone is said to extinguish the spirit, in one way, by extinguishing his fervor, either in himself or in another. Romans 12:11: "fervent in spirit." For when someone wills to do something good from the fervor of the Holy Spirit, or also when some good movement arises, and he himself impedes it, he extinguishes the Holy Spirit. Acts 7:51: "you have always resisted the Holy Spirit." In another way, by sinning mortally. For the Holy Spirit in himself always lives, but in us he lives when he makes us live in him; but when someone sins mortally, the Holy Spirit does not live in him. Wisdom 1:5: "for the Holy Spirit of discipline will flee the deceitful," etc. In a third way, by hiding it, as if he were to say: if you have the gift of the Holy Spirit, use it for the benefit of your neighbors. Ecclesiasticus 20:32: "hidden wisdom and unseen treasure, what use is there in either?" Matthew 5:15: "no one lights a lamp and puts it under a bushel," etc. "Do not despise prophecies." For some among these were endowed with the spirit of prophecy, who were reckoned by these others as insane. 1 Corinthians 14:1: "be zealous for spiritual things, but rather that you may prophesy." Or "prophecies," that is, divine teaching. For those expounding divine teaching are called prophets; as if he were to say: do not despise the words of God and the preachings. Jeremiah 20:8: "the word of the Lord has become a reproach and a derision all the day." Then when he says "but test all things," he shows how they should conduct themselves toward all things, and it is one point, that in all things they use discretion. Romans 12:1: "your reasonable service." In this matter there ought to be diligent examination, choice of the good, rejection of the bad. As to the first he says "do not despise prophecies," yet "test all things," namely those that are doubtful. For manifest things do not need examination. 1 John 4:1: "do not believe every spirit." Job 12:8: "does not the ear discern words?" As to the second he says "hold fast what is good." Galatians 4:18: "but be zealous for good, in a good thing, always." As to the third he says "abstain from every appearance of evil." Isaiah 7:15: "that he may know to refuse the evil and choose the good." And he says "appearance," because we ought also to avoid even those things which have the likeness of malice, which namely we could not observe before men without scandal to them. Then when he says "but he himself," he adds a prayer, and concerning this he does three things: first he prays for them; second he gives hope of being heard; third he gives special admonitions. He says therefore: thus I admonish, but it avails nothing unless God gives grace. Hence "may the God of peace himself sanctify you." Leviticus 21:8: "I am the Lord, who sanctifies you," etc. "In every part," that is, that you may be wholly holy. And this "that [your] whole [spirit]," etc. For on the occasion of these words some said that in man the spirit is one thing and the soul another, positing two souls in man, one which animates, the other which reasons. And these have been condemned in ecclesiastical teachings. Hence it should be known that these do not differ according to essence, but according to power. For in our soul there are certain powers which are acts of bodily organs, as are the powers of the sensitive part. There are others, which are not acts of such organs, but are abstracted from them, as are the powers of the intellective part. And these are called "spirit," as being immaterial and separated in some way from the body, inasmuch as they are not acts of the body, and they are also called "mind." Ephesians 4:23: "be renewed in the spirit of your mind." But insofar as it animates, it is called "soul," because this is proper to it. And Paul here speaks properly. For three things concur in sinning: reason, sensuality, and the execution of the body. He wishes therefore that there be sin in none of these. Not in reason; hence he says "that [your] spirit," that is, your mind, "may be kept whole." For in every sin reason is corrupted, according as every evil man is ignorant. Likewise, nor in sensuality, hence he says "soul." Likewise, nor in body; and therefore he says "and body." But this happens thus, when it is kept immune from sin. And he says "without blame," not "without sin," which belongs to Christ alone; but to be without blame belongs also to others, who, even if they commit venial sins, do not nevertheless commit grave ones, and ones by which the neighbor is scandalized. Luke 1:6: "walking in all the commandments and justifications of the Lord without blame." And he adds "at the coming," etc., namely by persevering until the end of life. Or "whole spirit" refers to the gift of the Holy Spirit, as if he were to say: may the gift of the Holy Spirit, which you have, be whole. Then when he says "faithful," etc., he gives hope of being heard; as if he were to say: as I hope, so it will be, because "he also who has called [you] will do [it]," that is, will fulfill it. Ps. 144:13: "the Lord is faithful in all his words," etc. Romans 8:30: "whom he called, these he also justified," etc. Lastly he appends familiar admonitions: namely prayer, at "pray"; likewise mutual peace, at "greet all the brothers with a holy kiss," not a treacherous one, like Judas, Matthew 26:49, nor a lustful one, like the lustful woman, Proverbs 7:10. "That it be read," etc. For he feared lest the prelates, on account of certain things that were here, might conceal it. Proverbs 11:26: "he who hides grain will be cursed among the peoples," etc. Lastly he concludes the epistle with a salutation.”

“Now we exhort you, brethren,.... This is said either to the ministers of the word that laboured among them, presided over them, and admonished them; and the rather, because some of these things here directed to are pressed upon the members of the church in Th1 5:11 and which otherwise must make a repetition here; or to the members in conjunction with their pastors: warn them that are unruly; or disorderly, idle persons, working not at all, busying themselves with other men's matters, and living upon the church's stock, reprove them for their sloth, exhort them to work with their own hands, to do their own business, and with quietness eat their own bread; or such who keep not their places in the church, but are like soldiers that go out of their rank, desert their companies, and fly from their colours, or stand aside, rebuke these, and exhort them to fill up their places, to abide by the church, and the ordinances of Christ; or such who are contentious and quarrelsome, turbulent, headstrong, and unruly, that cause and foment animosities and divisions, check them, admonish them, lay them under censure, for such a custom and practice is not to be allowed of in the churches of Christ. Comfort the feebleminded: such as are not able to bear the loss of near and dear relations; are ready to stagger under the cross, and at the reproaches and persecutions of the world; and are almost overset with the temptations of Satan; and are borne down and discouraged with the corruptions of their hearts, speak a comfortable word to them, encourage them with the doctrines of grace, and the promises of the Gospel. Support the weak; who are weak in faith and knowledge, strengthen them, hold them up; or as the Syriac version renders it, "take the burden of the weak" and carry it, bear their infirmities, as directed in Rom 15:1, be patient towards all men; towards the unruly, the feebleminded, and the weak as well as to believers; give place to wrath, and leave vengeance to him to whom it belongs; exercise longsuffering and forbearance with fellow creatures and fellow Christians.”

“Warn them that are unruly - The whole phraseology of this verse is military; I shall consider the import of each term. Ατακτους· Those who are out of their ranks, and are neither in a disposition nor situation to perform the work and duty of a soldier; those who will not do the work prescribed, and who will meddle with what is not commanded. There are many such in every Church that is of considerable magnitude. Comfort the feeble-minded - Τους ολιγοψυχους· Those of little souls; the faint-hearted; those who, on the eve of a battle, are dispirited, because of the number of the enemy, and their own feeble and unprovided state. Let them know that the battle is not theirs, but the Lord's; and that those who trust in him shall conquer. Support the weak - Αντεχεσθε των ασθενων· Shore up, prop them that are weak; strengthen those wings and companies that are likely to be most exposed, that they be not overpowered and broken in the day of battle. Be patient toward all - Μακροθυμειτε προς παντας· The disorderly, the feeble-minded, and the weak, will exercise your patience, and try your temper. If the troops be irregular, and cannot in every respect be reduced to proper order and discipline, let not the officers lose their temper nor courage; let them do the best they can; God will be with them, and a victory will give confidence to their troops. We have often seen that the Christian life is compared to a warfare, and that the directions given to soldiers are, mutatis mutandis; allowing for the different systems, suitable to Christians. This subject has been largely treated on, Ephesians 6. The ministers of Christ, being considered as officers, should acquaint themselves with the officers' duty. He who has the direction and management of a Church of God will need all the skill and prudence he can acquire.”

“brethren--This exhortation to "warm (Greek, 'admonish,' as in Th1 5:12) the unruly (those 'disorderly' persons, Th2 3:6, Th2 3:11, who would not work, and yet expected to be maintained, literally, said of soldiers who will not remain in their ranks, compare Th1 4:11; also those insubordinate as to Church discipline, in relation to those 'over' the Church, Th1 5:12), comfort the feeble-minded (the faint-hearted, who are ready to sink 'without hope' in afflictions, Th1 4:13, and temptations)," applies to all clergy and laity alike, though primarily the duty of the clergy (who are meant in Th1 5:12)." support--literally, "lay fast hold on so as to support." the weak--spiritually. Paul practiced what he preached (Co1 9:22). be patient toward all men--There is no believer who needs not the exercise of patience "toward" him; there is none to whom a believer ought not to show it; many show it more to strangers than to their own families, more to the great than to the humble; but we ought to show it "toward all men" [BENGEL]. Compare "the long-suffering of our Lord" (Co2 10:1; Pe2 3:15).”
