Now I beseech you, brethren, to mark them who make dissensions and offences contrary to the doctrine which you have learned, and avoid them.

“For these are they "who by good words and fair speeches lead astray the hearts of the simple, and, while offering them blessings, lead them astray." [Romans 16:17-19] Let us, therefore, fear the judgment which awaits teachers. For a severe judgment will those teachers receive "who teach, but do not," [Matthew 23:3] and those who take upon them the name of Christ falsely, and say: We teach the truth, and yet go wandering about idly, and exalt themselves, and make their boast in the mind of the flesh. [Colossians 2:18]”

“Again an exhortation, and prayer after the exhortation. For after telling them to "mark them which cause divisions," and not to listen to them, he proceeds, "And the God of peace shall bruise Satan under your feet shortly:" and, "The grace of our Lord be with you." And notice how gently too he exhorts them: doing it not in the character of a counsellor, but that of a servant, and with much respect. For he calls them brethren, and supplicates them likewise. For, "I beseech you, brethren," (he says). Then he also puts them on the defensive by showing the deceitfulness of those who abused them. For as though they were not at once to be discerned, he says, "I beseech you to mark," that is, to be exceedingly particular about, and to get acquainted with, and to search out thoroughly-whom, pray? why, "those that cause divisions and offences, contrary to the doctrine which ye have learned." For this is, if anything the subversion of the Church, the being in divisions. This is the devil's weapon, this turneth all things upside-down. For so long as the body is joined into one, he has no power to get an entrance, but it is from division that the offence cometh. And whence is division? From opinions contrary to the teaching of the Apostles. And whence come opinions of this sort? From men's being slaves to the belly, and the other passions. For "such," he says, "serve not the Lord, but their own belly." And so there would be no offence, there would be no division, unless some opinion were thought of contrary to the doctrine of the Apostles. And this he here points out by saying, "contrary to the doctrine." And he does not say which we have taught, but "which ye have learned," so anticipating them, and showing that they were persuaded of and had heard them and received them. And what are we to do to those who make mischief in this way? He does not say have a meeting and come to blows, but "avoid them." For if it was from ignorance or error that they did this, one ought to set them right. But if they sin willingly, spring away from them. And in another place too he says this. For he says, "Withdraw from every brother that walketh disorderly" (2 Thess. iii. 6): and in speaking to Timothy about the coppersmith, he gives him the like advice, and says, "Of whom be thou ware also." (2 Tim. iv. 15.) Then also to lash those who dare to do such things, he mentions also the reason of their devising this division. "For they that are such," he says, "serve not our Lord Christ, but their own belly." And this he said too when he wrote to the Philippians, "Whose god is their belly." But here he appears to me to intimate those of the Jews, whom he ever uses particularly to find fault with as gluttonous. For in writing to Titus too, he said of them, "Evil beasts, slow bellies." And Christ also blames them on this head: "Ye devour widows' houses," He says. And the Prophets accuse them of things of the kind. For, "My beloved," He says, "hath waxen fat and gross, and hath kicked" (Deut. xxxii. 15). Wherefore also Moses exhorted them, and said, "When thou hast eaten and drunken and art full, remember the Lord thy God." And in the Gospels, they who say to Christ, "What sign showest thou unto us?" (John vi. 30) pass over everything else, and remember the manna. So do they everywhere appear to be possessed with this affection. How then comest thou not to be ashamed at having slaves of the belly for thy teachers, when thou art a brother of Christ? Now the ground of the error is this, but the mode of attack is again a different disorder, viz. flattery. For it is by "fair speeches," he says, "that they deceive the hearts of the simple." For their attention reaches only to words; but their meaning is not such, for it is full of fraud. And he does not say that they deceive you, but "the hearts of the simple."”

“After the Apostle has enjoined whom they should greet, he here shows them whom they ought to avoid. And concerning this he does three things. First, he teaches whom they ought to avoid; second, he assigns the reason, at the words for such men, etc.; third, he promises them divine help for accomplishing this, at the words and the God of peace, etc. And because those whom he wished to be avoided proceeded fraudulently, deceiving under the appearance of piety, according to that word of Matthew 7:15: they come to you in sheep's clothing, but inwardly they are ravening wolves, therefore, first, he leads them to exercise caution, saying now I beseech you, brethren, to mark them which cause dissensions and offenses contrary to the doctrine which you have learned. Here, first, it should be considered that "to observe" is nothing other than to consider diligently, which indeed is sometimes taken in a good sense, sometimes in a bad sense. It is taken in a bad sense when someone diligently considers the condition and course of another in order to harm him, according to that word of Psalm 36:12: the sinner shall observe the just man, and shall gnash upon him with his teeth. And in Luke 14:1 it is said: and they watched him. It is taken in a good sense, in one way, when someone considers the precepts of God in order to do them. Exodus 23:21: observe therefore and hear his voice. In another way, when someone diligently considers good men in order to imitate them, according to that word of Philippians 3:17: be followers of me, brethren, and mark them which walk so, as you have us for a pattern. Third, evil men are observed in order to be avoided, and it is taken in this sense here. For there were certain men converted to the faith from among the Jews, who preached that the precepts of the law were to be observed, and from this, first, dissensions and sects followed in the Church, while some of them adhered to the error and others persisted in the true faith. Galatians 5:20: dissensions, sects, etc. Second, offenses and scandals followed, of which it was treated above in chapter 14, while some judged others and others despised others — these are the ones who cause dissensions and offenses. Isaiah 57:14: take away the stumbling-blocks out of the way of my people. Now he says contrary to the doctrine which you have learned from the true apostles of Christ, in order to show that such dissensions and scandals arose from the falsity of their teaching. Galatians 1:9: if any man preach any other gospel unto you than that which you have received, let him be anathema. Second, he warns that, once recognized, they should be avoided, saying and avoid them, that is, flee their doctrine and their company. Psalm 118:115: depart from me, you malignant ones, and I will search the commandments of my God. Then when he says for such men, etc., he assigns two reasons for what he had said, of which the first is taken from the side of those whom he wishes to be avoided. And first he describes their intention, saying for such men do not serve our Lord Christ, but their own belly. For they did not preach for the glory of Christ, but for gain, so as to fill their own belly. Philippians 3:18: many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ, whose God is their belly. Second, he describes their deception, saying and by good words and fair speeches deceive the hearts of the innocent, that is, of the simple and unlearned. Proverbs 14:15: the innocent believeth every word. By good words, in which they pretend to sanctity, according to that word of Psalm 27:3: who speak peace with their neighbor, but evils are in their hearts. And fair speeches, namely by which they bless and flatter those who follow them. Isaiah 3:12: O my people, they that call thee blessed, the same deceive thee. Malachi 2:2: I will curse your blessings. He assigns the second reason from the condition of the Romans, who showed themselves ready to follow after both good and evil. Hence, first, he commends them for their readiness for good, saying for your obedience, by which you readily obeyed the faith, is come abroad unto all men, because of the dominion which the Romans then held over the other nations. Hence what was done by the Romans was readily spread abroad to others. Above, in chapter 1:8: your faith is spoken of throughout the whole world. I am glad therefore on your behalf, namely because you have obeyed the faith, and this in charity, of which it is said in 1 Corinthians 13:6, that it rejoiceth not in iniquity, but rejoiceth with the truth. Second, he makes them cautious against evil, saying but yet I would have you wise unto that which is good, namely that you cleave to that which is good — 1 Thessalonians, the last chapter: hold fast that which is good — and simple concerning evil, namely lest through some simplicity you decline toward evil, so that your simplicity may be such that you deceive no one unto evil. Matthew 10:16: be ye wise as serpents, and simple as doves. Conversely, of certain men it is said in Jeremiah 4:22: they are wise to do evil, but to do good they have no knowledge. Then when he says and the God of peace, etc., he promises them divine help against such deceivers. And first the promise is set down, when he says and the God of peace, that is, its author, who hates the dissensions that these men cause, shall bruise Satan, that is, the Devil who through these pseudo-apostles strives to deceive you, under your feet, because indeed you will conquer him through your wisdom. And this shall happen shortly, namely at my coming. Luke 10:19: behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy. Malachi, the last chapter: you shall tread down the wicked, when they shall be as ashes under the sole of your feet. Second, the prayer for obtaining this is set down, when he says the grace of our Lord Jesus Christ be with you, which indeed suffices to protect you. 2 Corinthians 12:9: my grace is sufficient for thee. Then when he says Timothy my workfellow saluteth you, etc., he greets them on behalf of others, saying Timothy my workfellow saluteth you, namely in the preaching of the Gospel. 1 Corinthians 4:17: I have sent unto you Timotheus, who is my beloved son, and faithful, etc. He adds, moreover, and Lucius, and Jason, and Sosipater, my kinsmen, who were Jews, greet you, namely. Now there was a certain notary of Paul named Tertius, to whom Paul granted that he should greet the Romans in his own person. Hence it is added I Tertius, who wrote this epistle, salute you in the Lord. Then he says Gaius mine host saluteth you, to whom the third canonical epistle of John is addressed, in which he is commended for the charity which he showed to the saints. And of the whole church, namely which was gathered in his house, or which was in that province. Then he says Erastus the chamberlain of the city saluteth you, namely he who kept the common chest, that is, the common revenues of the city, and Quartus a brother, that is, a believer, by name Quartus. Then he greets them on his own behalf, saying the grace of our Lord Jesus Christ be with you all. Amen. And he ends the epistle with an act of thanksgiving, saying now to him, namely to God who is the Trinity, that is of power to establish you — 1 Peter, the last chapter: after that ye have suffered a while, he himself shall perfect, confirm, and establish you — and this in the faith which is according to my Gospel, that is, according to the Gospel which I preach. 1 Corinthians 15:11: whether it were I or they, so we preach, and so ye believed. And also according to the preaching of Jesus Christ, who first preached the Gospel, according to that word of Hebrews 2:3: which at the first began to be spoken by the Lord. Hence it is said in Matthew 4:23, that Jesus went about preaching the gospel of the kingdom. Now it is added, according to the revelation of the mystery, that is, of the secret, which indeed can be referred to what he had said above, according to my Gospel; or because in the Gospel itself the secret of the divine incarnation is revealed, according to that word above in chapter 1:17: the righteousness of God is revealed therein; or because to the Apostle himself the Gospel was revealed. 1 Corinthians 2:10: but unto us God hath revealed them by his Spirit. Concerning this secret it is said in Isaiah 24:16: my secret to myself. Or this may better be referred to what he had said, to establish, as if he were saying: God can establish you in my Gospel and preaching, and this according to the revelation of the mystery, that is, of the secret, namely concerning the conversion of the Gentiles, as is found in Ephesians 3:8 and following: unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles, and make all men see what is the dispensation of the mystery, etc. Hence he also adds since the world began, because indeed it was hidden among men that the Gentiles were to be converted to the faith. Now he calls these times eternal as if long-enduring, because from the beginning of the world this was hidden, as also is said in Psalm 75:4: thou, enlightening wonderfully from the everlasting mountains. And it can be said that the eternal times are called eternity itself, of which it is said in Isaiah 57:15: the high and eminent one, inhabiting eternity, so that just as the simple essence of God is described by a certain likeness through corporeal dimensions, according to that word of Job 11:9: the measure thereof is longer than the earth, and broader than the sea, so also his simple eternity is designated through eternal times, insofar as it contains all times. Now he adds that, namely the mystery, is now made manifest, concerning the conversion of the Gentiles, by the scriptures of the prophets, that is, according as the prophets foretold, as was made clear above in chapter 15. Hence in Ephesians 3:5 and following it is said: which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit, that the Gentiles should be fellow-heirs, etc. Now it is made manifest through the fulfillment of the work by the command of God. Hence according to the commandment of the everlasting God, who indeed by his eternal purpose does in time the things which he wills, which command of God indeed is made known to all nations for the obedience of faith, that is, that all nations may obey the faith. Above, in chapter 1:5: for obedience to the faith among all nations. But if we speak of the mystery of the incarnation, the text is to be construed thus: of the mystery, I say, kept secret since the world began, because before it was not so manifest. Which mystery, I say, is now made manifest by the scriptures of the prophets, who foretold this according to the commandment of the everlasting God, who willed the mystery of the incarnation to be made manifest, and this for the obedience of faith among all nations. Of the mystery, I say, although kept secret among men, yet known only to God who is wise, because he alone knew this, and those to whom he willed to reveal it, because, as it is said in 1 Corinthians 2:11: the things of God knoweth no man, but the Spirit of God. Or it can be understood of him who alone is wise, namely by essence, as is said in Matthew 19:17 and Mark 10:18: none is good, save one, that is, God. Nor is the Son excluded by this, because the perfection of the whole Trinity is the same, just as, conversely, it is said: no man knoweth the Father, save the Son, Matthew 11:27 — the Father is not excluded from knowledge of himself. Now he adds by Jesus Christ; which is not to be understood in this sense, that God the Father is wise through Jesus Christ, because since for God to be wise is the same as to be, it would follow that the Father exists through the Son, which is unfitting; but this is to be referred to what he had said above: is now made manifest, namely through Jesus Christ. To whom, that is, to Jesus Christ, be honor and glory, through the reverence of the whole creature, according to that word of Philippians 2:10: at the name of Jesus every knee should bow. And glory, namely as to the fullness of his divinity, just as it is added there: and every tongue should confess that the Lord Jesus Christ is in the glory of God the Father. And this not for a time, but for ever, world without end. Hebrews, the last chapter: Jesus Christ, the same yesterday, and today, and forever. He adds, moreover, for the confirmation of the truth: Amen. Or it can be construed thus: known only to the wise God, to whom, through Jesus Christ, is glory — who glorified God, according to that word of John 17:4: I have glorified thee on the earth. Now it should be noted that this construction is defective, and is to be supplied thus: to him who is able, etc., be honor and glory through Jesus Christ, to whom is honor and glory. But if the word "to whom" is not there, the construction will be straightforward.”

“The apostle having endeavoured by his endearing salutations to unite them together, it was not improper to subjoin a caution to take heed of those whose principles and practices were destructive to Christian love. And we may observe, I. The caution itself, which is given in the most obliging manner that could be: I beseech you, brethren. He does not will and command, as one that lorded it over God's heritage, but for love's sake beseeches. How earnest, how endearing, are Paul's exhortations! He teaches them, 1. To see their danger: Mark those who cause divisions and offences. Our Master had himself foretold that divisions and offences would come, but had entailed a woe on those by whom they come (Mat 18:7), and against such we are here cautioned. Those who burden the church with dividing and offending impositions, who uphold and enforce those impositions, who introduce and propagate dividing and offending notions, which are erroneous or justly suspected, who out of pride, ambition, affectation of novelty, or the like, causelessly separate from their brethren, and by perverse disputes, censures, and evil surmisings, alienate the affections of Christians one from another - these cause divisions and offences, contrary to, or different from (for that also is implied, it is para tēn didachēn), the doctrine which we have learned. Whatever varies from the form of sound doctrine which we have in the scriptures opens a door to divisions and offences. If truth be once deserted, unity and peace will not last long. Now, mark those that thus cause divisions, skopein. Observe them, the method they take, the end they drive at. There is need of a piercing watchful eye to discern the danger we are in from such people; for commonly the pretences are plausible, when the projects are very pernicious. Do not look only at the divisions and offences, but run up those streams to the fountain, and mark those that cause them, and especially that in them which causes these divisions and offences, those lusts on each side whence come these wars and fightings. A danger discovered is half prevented. 2. To shun it: "Avoid them. Shun all necessary communion and communication with them, lest you be leavened and infected by them. Do not strike in with any dividing interests, nor embrace any of those principles or practices which are destructive to Christian love and charity, or to the truth which is according to godliness. - Their word will eat as doth a canker." Some think he especially warns them to take heed of the judaizing teachers, who, under convert of the Christian name, kept up the Mosaical ceremonies, and preached the necessity of them, who were industrious in all places to draw disciples after them, and whom Paul in most of his epistles cautions the churches to take heed of. II. The reasons to enforce this caution. 1. Because of the pernicious policy of these seducers, Rom 16:18. The worse they are, the more need we have to watch against them. Now observe his description of them, in two things: - (1.) The master they serve: not our Lord Jesus Christ. Though they call themselves Christians, they do not serve Christ; do not aim at his glory, promote his interest, nor do his will, whatever they pretend. How many are there who call Christ Master and Lord, that are far from serving him! But they serve their own belly - their carnal, sensual, secular interests. It is some base lust or other that they are pleasing; pride, ambition, covetousness, luxury, lasciviousness, these are the designs which they are really carrying on. Their God is their belly, Phi 3:19. What a base master do they serve, and how unworthy to come in competition with Christ, that serve their own bellies, that make gain their godliness, and the gratifying of a sensual appetite the very scope and business of their lives, to which all other purposes and designs must truckle and be made subservient. (2.) The method they take to compass their design: By good words and fair speeches they deceive the hearts of the simple. Their words and speeches have a show of holiness and zeal for God (it is an easy thing to be godly from the teeth outward), and show of kindness and love to those into whom they instil their corrupt doctrines, accosting them courteously when they intend them the greatest mischief. Thus by good words and fair speeches the serpent beguiled Eve. Observe, They corrupt their heads by deceiving their hearts, pervert their judgments by slyly insinuating themselves into their affections. We have a great need therefore to keep our hearts with all diligence, especially when seducing spirits are abroad. 2. Because of the peril we are in, through our proneness and aptness to be inveigled and ensnared by them: "For your obedience has come abroad unto all men - you are noted in all the churches for a willing, tractable, complying people." And, (1.) Therefore, because it was so, these seducing teachers would be the more apt to assault them. The devil and his agents have a particular spite against flourishing churches and flourishing souls. The ship that is known to be richly laden is most exposed to privateers. The adversary and enemy covets such a prey, therefore look to yourselves, Jo2 1:8. "The false teachers hear that you are an obedient people, and therefore they will be likely to come among you, to see if you will be obedient to them." It has been the common policy of seducers to set upon those who are softened by convictions, and begin to enquire what they shall do, because such do most easily receive the impressions of their opinions. Sad experience witnesses how many who have begun to ask the way to Zion, with their faces thitherward, have fatally split upon this rock, which proves it to be much the duty of ministers, with a double care, to feed the lambs of the flock, to lay a good foundation, and gently to lead those that are with young. (2.) Though it were so, yet they were in danger from these seducers. This Paul suggests with a great deal of modesty and tenderness; not as one suspicious of them, but as one solicitous for them: "You obedience has come abroad unto all men; we grant this and rejoice in it: I am glad therefore on your behalf." Thus does he insinuate their commendation, the better to make way for the caution. A holy jealousy of our friends may very well comport with a holy joy in them. "You think yourselves a very happy people, and so do I too: but for all that you must not be secure: I would have you wise unto that which is good, and simple concerning evil. You are a willing good-natured people, but you had best take heed of being imposed upon by those seducers." A pliable temper is good when it is under good government; but otherwise it may be very ensnaring; and therefore he gives two general rules: - [1.] To be wise unto that which is good, that is, to be skilful and intelligent in the truths and ways of God. "Be wise to try the spirits, to prove all things, and then to hold fast that only which is good." There is need of a great deal of wisdom in our adherence to good truths, and good duties, and good people, lest in any of these we be imposed upon and deluded. Be ye therefore wise as serpents (Mat 10:16), wise to discern that which is really good and that which is counterfeit; wise to distinguish things that differ, to improve opportunities. While we are in the midst of so many deceivers, we have great need of that wisdom of the prudent which is to understand his way, Pro 14:8. [2.] To be simple concerning evil - so wise as not to be deceived, and yet so simple as not to be deceivers. It is a holy simplicity, not to be able to contrive, nor palliate, nor carry on, any evil design; akeraious - harmless, unmixed, inoffensive. In malice be you children, Co1 14:20. The wisdom of the serpent becomes Christians, but not the subtlety of the old serpent. We must withal be harmless as doves. That is a wisely simple man that knows not how to do any thing against the truth. Now Paul was the more solicitous for the Roman church, that it might preserve its integrity, because it was so famous; it was a city upon a hill, and many eyes were upon the Christians there, so that an error prevailing there would be a bad precedent, and have an ill influence upon other churches: as indeed it has since proved in fact, the great apostasy of the latter days taking its rise from that capital city. The errors of leading churches are leading errors. When the bishop of Rome fell as a great star from heaven (Rev 8:10), his tail drew a third part of the stars after him, Rev 12:4. 3. Because of the promise of God, that we shall have victory at last, which is given to quicken and encourage, not to supersede, our watchful cares and vigorous endeavours. It is a very sweet promise (Rom 16:20): The God of peace shall bruise Satan under your feet. (1.) The titles he gives to God: The God of peace, the author and giver of all good. When we come to God for spiritual victories, we must not only eye him as the Lord of hosts, whose all power is, but as the God of peace, a God at peace with us, speaking peace to us, working peace in us, creating peace for us. Victory comes from God more as the God of peace than as the God of war; for, in all our conflicts, peace is the thing we must contend for. God, as the God of peace, will restrain and vanquish all those that cause divisions and offences, and so break and disturb the peace of the church. (2.) The blessing he expects from God - a victory over Satan. If he mean primarily those false doctrines and seducing spirits spoken of before, of which Satan was the prime founder and author, yet doubtless, it comprehends all the other designs and devices of Satan against souls, to defile, disturb, and destroy them, all his attempts to keep us from the purity of heaven, the peace of heaven here, and the possession of heaven hereafter. Satan tempting and troubling, acting as a deceiver and as a destroyer, the God of peace will bruise under our feet. He had cautioned them before against simplicity: now they, being conscious of their own great weakness and folly, might think, "How shall we evade and escape these snares that are laid for us? Will not these adversaries of our souls be at length too hard for us?" "No," says he, "fear not; though you cannot overcome in your own strength and wisdom, yet the God of peace will do it for you; and through him that loved us we shall be more than conquerors." [1.] The victory shall be complete: He shall bruise Satan under your feet, plainly alluding to the first promise the Messiah made in paradise (Gen 3:15), that the seed of the woman should break the serpent's head, which is in the fulfilling every day, while the saints are enabled to resist and overcome the temptations of Satan, and will be perfectly fulfilled when, in spite of all the powers of darkness, all that belong to the election of grace shall be brought triumphantly to glory. When Joshua had conquered the kings of Canaan, he called the captains of Israel to set their feet upon the necks of those kings (Jos 10:24), so will Christ, our Joshua, enable all his faithful servants and soldiers to set their feet upon Satan's neck, to trample upon, and triumph over, their spiritual enemies. Christ hath overcome for us; disarmed the strong man armed, broken his power, and we have nothing to do but to pursue the victory and divide the spoil. Let this quicken us to our spiritual conflict, to fight the good fight of faith - we have to do with a conquered enemy, and the victory will be perfect shortly. [2.] The victory shall be speedy: He shall do it shortly. Yet a little while, and he that shall come will come. He hath said it, Behold, I come quickly. When Satan seems to have prevailed, and we are ready to give up all for lost, then will the God of peace cut the work short in righteousness. It will encourage soldiers when they know the war will be at an end quickly, in such a victory. Some refer it to the happy period of their contentions in true love and unity; others to the period of the church's persecutions in the conversion of the powers of the empire to Christianity, when the bloody enemies of the church were subdued and trampled on by Constantine, and the church under his government. It is rather to be applied to the victory which all the saints shall have over Satan when they come to heaven, and shall be for ever out of his reach, together with the present victories which through grace they obtain in earnest of that. Hold out therefore, faith and patience, yet a little while; when we have once got through the Red Sea, we shall see our spiritual enemies dead on the shore, and triumphantly sing the song of Moses and the song of the Lamb. To this therefore he subjoins the benediction, The grace of our Lord Jesus Christ be with you - the good-will of Christ towards you, the good work of Christ in you. This will be the best preservative against the snares of heretics, and schismatics, and false teachers. If the grace of Christ be with us, who can be against us so as to prevail? Be strong therefore in the grace which is in Christ Jesus. Paul, not only as a friend, but as a minister and an apostle, who had received grace for grace, thus with authority blesses them with this blessing, and repeats it, Rom 16:24.”

“For they that are such serve not our Lord Jesus Christ,.... They do not preach him, but themselves; they do not seek the things of Christ, his honour and glory, the spread of his Gospel, and the enlargement of his kingdom and interest; they seek their own things, worldly honour and applause, riches, wealth, and grandeur; they seek to please men, and so are not the servants of Christ: they introduced the observance of meats and drinks in to the kingdom of Christ, which it do not consist of, and neglected the doctrines of righteousness and peace, from whence springs joy in the Holy Ghost, and so in these spiritual things did not serve Christ; and therefore, as they were not acceptable to God, were not to be approved of by Christian men, but to be marked and avoided: but their own belly; which they made a god of, and devoted themselves to the service of all their views were to gratify and indulge their sensual appetite. The false teachers among the Jews were particularly addicted to this vice: hence the apostle sometimes calls them dogs, Phi 3:2, on account of their voraciousness, and who, in Isaiah's time, were greedy ones that could never have enough, Isa 56:11; and in our Lord's time devoured widows' houses, under a pretence of long prayers for them, Mat 23:14; and were like the Cretians, evil beasts, and slow bellies, Tit 1:12, unwilling to labour, and lived upon the spoil of others: and by good words, and fair speeches, deceive the hearts of the simple: they were deceivers; they lay in wait to deceive, made use of the hidden things of dishonesty, walked in craftiness, and handled the word of God deceitfully; and therefore to be marked and avoided: they deceived "the simple", harmless, and innocent, that think no evil, nor are aware of any; who have little understanding of things; persons of weak minds, easy to be imposed upon; very credulous, ready to believe every word, so the simple man does, as Solomon says, Pro 14:15; and such false teachers choose to tamper with, and make their attacks upon, being able to gain upon them the most easily, as their father the devil, the old serpent, did, when he first assailed human nature: the "hearts" of these they deceive; they work upon their affections, blind their understandings, impose on their judgments, and corrupt their minds from the simplicity that is in Christ: and this they do "by good words and fair speeches"; either by making use of the words of Scripture, and a show of arguments taken from thence; so Satan cited Scripture in his dispute with our Lord; and so heretics, in all ages, have pretended toil in favour of their principles, by which means they have gained on many to follow their pernicious ways; or by using words and phrases that faithful ministers of Christ use, such as the grace of God, the righteousness of Christ, the Spirit of Christ, but in a different sense; as some among us now frequently make mention of them, when they mean no more by them than the light of nature within them, and the dictates of a natural conscience; or by an elegant style, a set of fine words, a flow of rhetorical expressions, great swelling words of vanity, which such men generally affect, and so work themselves into the admiration of the common people; or by doctrines suited to the carnal minds and reasonings of men, which tickle human nature, and swell it with pride and vanity; as by preaching up the purity and power of it, asserting man's free will, and the strength of it to that which is good; the capacity of man to keep the law, and perform good works; justification by them before God, and acceptance with him, on account of them; atonement for sins committed, by repentance and reformation; that God does not regard trifling things, some sins are venial, and easily passed over; that concupiscence is no sin; God does not rigorously exact duty, he takes the will for the deed, and is merciful unto all, and if but sincere, there is no doubt of heaven; and such men, generally speaking, instead of correcting vice, and reproving men for their sins, connive at them, indulge them in them, soothe and flatter, commend and defend them, whereby they attach them to their persons and interest.”

“Mark them which cause divisions - Several MSS. read ασφαλως σκοπειτε, look sharply after them; let them have no kiss of charity nor peace, because they strive to make divisions, and thus set the flock of Christ at variance among themselves; and from these divisions, offenses (σκανδαλα, scandals) are produced; and this is contrary to that doctrine of peace, unity, and brotherly love which you have learned. Look sharply after such that they do you no evil, and avoid them - give them no countenance, and have no religious fellowship with them.”

“Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned--"which ye learned." and avoid them--The fomentors of "divisions" here referred to are probably those who were unfriendly to the truths taught in this epistle, while those who caused "offenses" were probably those referred to in Rom 14:15 as haughtily disregarding the prejudices of the weak. The direction as to both is, first, to "mark" such, lest the evil should be done ere it was fully discovered; and next, to "avoid" them (compare Th2 3:6, Th2 3:14), so as neither to bear any responsibility for their procedure, nor seem to give them the least countenance.”
