Here begins the second part of this epistle, in which he exhorts them to the practice of Christian virtues. (Witham)
Another part of the Epistle containing precepts of Christian life, the sum whereof is this, that every man behave himself as it is meet for so excellent grace of God. By this is meant the general calling of the faithful, which is this, to be holy, as our God is holy.
We have gone through the former part of this epistle, which consists of several important doctrinal truths, contained in the three preceding chapters. We enter now on the latter part of it, in which we have the most weighty and serious exhortations that can be given. We may observe that in this, as in most others of Paul's epistles, the former part is doctrinal, and fitted to inform the minds of men in the great truths and doctrines of the gospel, the latter is practical, and designed for the direction of their lives and manners, all Christians being bound to endeavour after soundness in the faith, and regularity in life and practice. In what has gone before we have heard of Christian privileges, which are the matter of our comfort. In what follows we shall hear of Christian duties, and what the Lord our God requires of us in consideration of such privileges vouchsafed to us. The best way to understand the mysteries and partake of the privileges of which we have read before is conscientiously to practise the duties prescribed to us in what follows: as, on the other hand, a serious consideration and belief of the doctrines that have been taught us in the foregoing chapters will be a good foundation on which to build the practice of the duties prescribed in those which are yet before us. Christian faith and Christian practice mutually befriend each other. In this chapter we have divers exhortations to important duties. I. One that is more general, ver 1. II. An exhortation to mutual love, unity, and concord, with the proper means and motives to promote them, ver 2-16. III. An exhortation to Christian purity and holiness of life; and that both more general (ver 17-24) and in several particular instances, ver 25, to the end.
Verses 1-6 Nothing is pressed more earnestly in the Scriptures, than to walk as becomes those called to Christ's kingdom and glory. By lowliness, understand humility, which is opposed to pride. By meekness, that excellent disposition of soul, which makes men unwilling to provoke, and not easily to be provoked or offended. We find much in ourselves for which we can hardly forgive ourselves; therefore we must not be surprised if we find in others that which we think it hard to forgive. There is one Christ in whom all believers hope, and one heaven they are all hoping for; therefore they should be of one heart. They had all one faith, as to its object, Author, nature, and power. They all believed the same as to the great truths of religion; they had all been admitted into the church by one baptism, with water, in the name of the Father, and of the Son, and of the Holy Ghost, as the sign of regeneration. In all believers God the Father dwells, as in his holy temple, by his Spirit and special grace.
I. The means of unity: Lowliness and meekness, long-suffering, and forbearing one another in love, v. 2. By lowliness we are to understand humility, entertaining mean thoughts of ourselves, which is opposed to pride. By meekness, that excellent disposition of soul which makes men unwilling to provoke others, and not easily to be provoked or offended with their infirmities; and it is opposed to angry resentments and peevishness. Long-suffering implies a patient bearing of injuries, without seeking revenge. Forbearing one another in love signifies bearing their infirmities out of a principle of love, and so as not to cease to love them on the account of these. The best Christians have need to bear one with another, and to make the best one of another, to provoke one another's graces and not their passions. We find much in ourselves which it is hard to forgive ourselves; and therefore we must not think it much if we find that in others which we think hard to forgive them, and yet we must forgive them as we forgive ourselves. Now without these things unity cannot be preserved. The first step towards unity is humility; without this there will be no meekness, no patience, or forbearance; and without these no unity. Pride and passion break the peace, and make all the mischief. Humility and meekness restore the peace, and keep it. Only by pride comes contention; only by humility comes love. The more lowly-mindedness the more like-mindedness. We do not walk worthy of the vocation wherewith we are called if we be not meek and lowly of heart: for he by whom we are called, he to whom we are called, was eminent for meekness and lowliness of heart, and has commanded us therein to learn of him.
II. The nature of that unity which the apostle prescribes: it is the unity of the Spirit, v. 3. The seat of Christian unity is in the heart or spirit: it does not lie in one set of thoughts, nor in one form and mode of worship, but in one heart and one soul. This unity of heart and affection may be said to be of the Spirit of God; it is wrought by him, and is one of the fruits of the Spirit. This we should endeavour to keep. Endeavouring is a gospel word. We must do our utmost. If others will quarrel with us, we must take all possible care not to quarrel with them. If others will despise and hate us, we must not despise and hate them. In the bond of peace. Peace is a bond, as it unites persons, and makes them live friendly one with another. A peaceable disposition and conduct bind Christians together, whereas discord and quarrelling disband and disunite their hearts and affections. Many slender twigs, bound together, become strong. The bond of peace is the strength of society. Not that it can be imagined that all good people, and all the members of societies, should be in every thing just of the same length, and the same sentiments, and the same judgment: buy the bond of peace unites them all together, with a non obstante to these. As in a bundle of rods, they may be of different lengths and different strength; but, when they are tied together by one bond, they are stronger than any, even than the thickest and strongest was of itself.
In one hope of your vocation. The three great reasons that we have to love one another are contained in this verse, because we have but one body, of which Christ is the head. We are all animated by the same spirit, viz. the Holy Ghost, who is given to us all, and we all live in the same hope of eternal happiness. (Calmet)
1. Consider how many unities there are that are the joy and glory of our Christian profession. There should be one heart; for there is one body, and one spirit, v. 4. Two hearts in one body would be monstrous. If there be but one body, all that belong to that body should have one heart. The Catholic church is one mystical body of Christ, and all good Christians make up but one body, incorporated by one charter, that of the gospel, animated by one Spirit, the same Holy Spirit who by his gifts and graces quickens, enlivens, and governs that body. If we belong to Christ, we are all actuated by one and the same Spirit, and therefore should be one. Even as you are called in one hope of your calling. Hope is here put for its object, the thing hoped for, the heavenly inheritance, to the hope of which we are called. All Christians are called to the same hope of eternal life. There is one Christ that they all hope in, and one heaven that they are all hoping for; and therefore they should be of one heart. One Lord (v. 5), that is, Christ, the head of the church, to whom, by God's appointment, all Christians are immediately subject. One faith, that is, the gospel, containing the doctrine of the Christian faith: or, it is the same grace of faith (faith in Christ) whereby all Christians are saved. One baptism, by which we profess our faith, being baptized in the name of the Father, Son, and Holy Ghost; and so the same sacramental covenant, whereby we engage ourselves to the Lord Christ. One God and Father of all, v. 6. One God, who owns all the true members of the church for his children; for he is the Father of all such by special relation, as he is the Father of all men by creation: and he is above all, by his essence, and with respect to the glorious perfections of his nature, and as he has dominion over all creatures and especially over his church, and through all, by his providence upholding and governing them: and in you all, in all believers, in whom he dwells as in his holy temple, by his Spirit and special grace. If then there be so many ones, it is a pity but there should be one more—one heart, or one soul.
