Let us then follow, etc. He recalls us, as much as possible, from a mere regard to meats, to consider those greater things which ought to have the first place in all our actions, and so to have the precedence. We must indeed eat, that we may live; we ought to live, that we may serve the Lord; and he serves the Lord, who by benevolence and kindness edifies his neighbor; for in order to promote these two things, concord and edification, all the duties of love ought to be exercised. Lest this should be thought of little moment, he repeats the sentence he had before announced, -- that corruptible meat is not of such consequence that for its sake the Lord's building should be destroyed. For wherever there is even a spark of godliness, there the work of God is to be seen; which they demolish, who by their unfeeling conduct disturb the conscience of the weak. But it must be noticed, that edification is joined to peace; because some, not unfrequently, too freely indulge one another, so that they do much harm by their compliances. Hence in endeavoring to serve one another, discretion ought to be exercised, and utility regarded, so that we may willingly grant to our brother whatever may be useful to further his salvation. So Paul reminds us in another place: "All things," he says, "are lawful to me; but all things are not expedient;" and immediately he adds the reason, "Because all things do not edify." (1-Corinthians 10:23.) Nor is it also in vain that he repeats again, For meat destroy not, [1] etc., intimating, that he required no abstinence, by which there would be, according to what he had said before, any loss to piety: though we eat not anything we please, but abstain from the use of meats for the sake of our brethren; yet the kingdom of God continues entire and complete.

Footnotes

1 - This is a similar, but not the same sentence as in Romans 14:15. The verb is different, katalue; which means to undo, to loosen, to pull down; and as "work" follows, which, as Calvin and others think, is to be understood of God's building, the work of edifying or building up his people, the verb may in this sense be rendered here, "Pull not down the work of God." But here, as in Romans 14:15, it is the tendency of the deed that is to be considered, and the effect as far as man's doing was concerned. The Apostle says nothing of what God would do. -- Ed.

Let us therefore follow - The object of this verse is to persuade the church at Rome to lay aside their causes of contention, and to live in harmony. This exhortation is founded on the considerations which the apostle had presented, and may be regarded as the conclusion to which the argument had conducted him.
The things which make for peace - The high purposes and objects of the Christian religion, and not those smaller matters which produce strife. If men aim at the great objects proposed by the Christian religion, they will live in peace. If they seek to promote their private ends, to follow their own passions and prejudices, they will be involved in strife and contention. There "are" great common objects before "all" Christians in which they can unite, and in the pursuit of which they will cultivate a spirit of peace. Let them all strive for holiness; let them seek to spread the gospel; let them engage in circulating the Bible, or in doing good in any way to others, and their smaller matters of difference will sink into comparative unimportance, and they will unite in one grand purpose of saving the world. Christians have more things in which they "agree" than in which they differ. The points in which they are agreed are of infinite importance; the points on which they differ are commonly some minor matters in which they may "agree to differ," and still cherish love for all who bear the image of Christ.
And things wherewith - That is, those things by which we may render "aid" to our brethren; the doctrines, exhortations, counsels, and other helps which may benefit them in their Christian life.
May edify - The word "edify" means properly to "build," as a house; then to "rebuild" or "reconstruct;" then to adorn or ornament; then to do any thing that will confer favor or advantage, or which will further an object. Applied to the church, it means to do anything by teaching, counsel, advice, etc. which will tend to promote its great object; to aid Christians, to enable them to surmount difficulties, to remove their ignorance, etc.; Acts 9:31; 1-Corinthians 8:1; 1-Corinthians 14:4. In these expressions the idea of a "building" is retained, reared on a firm, tried cornerstone, the Lord Jesus Christ; Ephesians 2:20; Isaiah 28:16. Compare Romans 9:33. Christians are thus regarded, according to Paul's noble idea Ephesians 2:20-22, as one great temple erected for the glory of God, having no separate interest, but as united for one object, and therefore bound to do all that is possible, that each other may be suited to their appropriate place, and perform their appropriate function in perfecting and adorning this temple of God.

Let us therefore follow - Far from contending about meats, drinks, and festival times, in which it is not likely that the Jews and Gentiles will soon agree, let us endeavor to the utmost of our power to promote peace and unanimity, that we may be instrumental in edifying each other, in promoting religious knowledge and piety instead of being stumbling-blocks in each other's way.

(18) Let us therefore follow after the things which make for peace, and things wherewith one may edify another.
(18) A general conclusion: the use of this liberty, indeed, and our whole life, ought to be concerned with the edifying of one another, insomuch that we consider that thing unlawful, by reason of the offence of our brother, which is of itself pure and lawful.

Let us therefore follow after the things, Since the kingdom of God is in part peace, and the man that serves Christ in this, as in other things, is accepted with God, and grateful to men, the apostle very pertinently exhorts to seek after such things,
which make for peace: not with God, for, for a sinful creature to make peace with God is impracticable and impossible, nor is there any exhortation to it in all the word of God; and if there was, it would be unnecessary here; since the persons here exhorted were such for whom peace with God was made by Christ, and who had a clear and comfortable sense of it in their own souls; and besides, for any to be put upon, or to attempt to make their peace with God, must highly reflect upon the methods of God's grace, in reconciling sinners to himself; and be injurious to the blood, sacrifice, and satisfaction of Christ, by which only peace is made: but the apostle means, either what makes for a man's own peace, or for the peace of others; the things which make for a man's own peace in his own conscience distressed with sin, are looking to, and dealing with the blood of Christ, which speaks peace and pardon; and the righteousness of Christ, which being apprehended by faith, a soul has peace with God through Christ; and also an embracing the Gospel, and the truths of it, which direct to Christ, which publish peace, and are the means of increasing and establishing a solid and well grounded peace, on the free grace of God and merits of Christ: attending on ordinances, and exercising a conscience void of offence towards God and men, are means of continuing and promoting a man's peace; he enjoys peace in them, though he do not derive it from them; yea, in the peace of others, is a man's own peace; and this is what is chiefly meant, a pursuing of things which make for the peace of others; of all men, and especially of saints; this is what should be eagerly followed after, closely pursued, and all ways and means should be made use of, to promote and secure it: this is the will of God; it is well pleasing to Christ, and a fruit of the Spirit; it is one part of the Gospel dispensation; church fellowship cannot be profitable and pleasant without it; it suits with the character of saints, who are sons of peace; and agrees with their privileges they enjoy, or have a right unto, as spiritual peace here, and eternal peace hereafter;
and things wherewith one may edify another. The church is often compared to a building, to a temple, a city, an house, and saints are the materials thereof; who are capable of being edified, or built up, yet more and more, both by words and by deeds; by words, by the ministry of the word, which is set up and continued among other things, for the edifying of the body of Christ; by praying with, and for each other; and by Christian conversation, about the experience of the grace of God, and doctrines of the Gospel, whereby saints may be useful in building up one another in their most holy faith; and so likewise by avoiding all filthy, frothy, and corrupt communication; all angry words and wrathful expressions, which tend not to profit, and are not for the use of edifying, but the contrary: moreover, edification is promoted by deeds, by acts of charity, or love; for charity edifies not by bare words but by loving in deed and in truth, by serving one another in love; for the spiritual body of Christ his church, makes increase unto the edifying of itself in love; and also by laying aside the use of things indifferent, when disagreeable to any of the brethren; for though all things may be lawful to be done by us, yet all things do not edify the brethren; and things which make for the edification of the body, as well as our own, are diligently to be sought after. The Vulgate Latin version, and some copies, read, "let us keep", or "observe those things wherewith one may edify another".

Many wish for peace, and talk loudly for it, who do not follow the things that make for peace. Meekness, humility, self-denial, and love, make for peace. We cannot edify one another, while quarrelling and contending. Many, for meat and drink, destroy the work of God in themselves; nothing more destroys the soul than pampering and pleasing the flesh, and fulfilling the lusts of it; so others are hurt, by wilful offence given. Lawful things may be done unlawfully, by giving offence to brethren. This takes in all indifferent things, whereby a brother is drawn into sin or trouble; or has his graces, his comforts, or his resolutions weakened. Hast thou faith? It is meant of knowledge and clearness as to our Christian liberty. Enjoy the comfort of it, but do not trouble others by a wrong use of it. Nor may we act against a doubting conscience. How excellent are the blessings of Christ's kingdom, which consists not in outward rites and ceremonies, but in righteousness, peace, and joy in the Holy Ghost! How preferable is the service of God to all other services! and in serving him we are not called to live and die to ourselves, but unto Christ, whose we are, and whom we ought to serve.

the things, &c.--more simply, "the things of peace, and the things of mutual edification."

Let us therefore follow . . . peace. Hence, charitably yield what grieves a brother.
May edify. Build up and make strong. Compare 1-Thessalonians 5:11.
For meat destroy not. A rigid insistence on eating the meat so offensive to some of the brethren may rend the church.
All things indeed are pure. All kinds of food are morally clean. See Romans 14:14.
But it is evil. It is morally unclean to him who eateth with hurt to his conscience.
It is good neither to eat flesh, etc. If eating any kind of food, or drinking wine, is the way of your brother's peace and security, it is better to abstain from both. Deny yourself rather than offend a brother. Compare 1-Corinthians 8:13. This maxim applies to all things indifferent. It applies to wine-drinking at our time. No Christian ought ever to set an example that may destroy another.
Hast thou faith? Art thou strong in the faith, and possessed of knowledge that the weaker brethren have not? Let God take not of it, but do not parade it before the weak.
Happy is he that condemneth not himself, etc. If one "allowed" that he had the right to eat all kinds of meats, etc., and did it to the injury of his brother, he would condemn himself, because he trampled on the law of love.
He that doubteth is damned if he eat. He is contrasted with him "who has faith" (Romans 14:22). He has not faith, or does not believe that it is right to eat these meats. Hence he is condemned ("damned") by his own conscience.
Whatsoever is not of faith is sin. The context shows that Paul means that whenever actions are done by a Christian which he does not believe are right, he sins in doing them. If he is doubtful whether they are right, he must not do them.

Peace and edification are closely joined. Practical divinity tends equally to peace and to edification. Controversial divinity less directly tends to edification, although sometimes, as they of old, we cannot build without it, Nehemiah 4:17.
