-1Ephesians 4:1-6, although cast in a hortatory form contain the final summary of the great doctrine of the Epistle--the UNITY OF THE CATHOLIC CHURCH--in words which have all the glowing freedom of spiritual enthusiasm, and all the clear-cut precision of a creed.

Thus (a) the ground of that unity is laid in that spiritual communion of each soul with the "one Spirit," the "one Lord," and the "one God and Father of all," which underlies all outward ordinance, and which no power of man can either give or take away, (b) The means of entering that unity is the "one baptism," ordained by Christ Himself, universal in the Christian world, capable of being ministered (though irregularly) by any Christian hand, (c) The graces, which in germ are conditions, and in full growth are effects, of such unity are the "one hope," the "one faith," the one "bond of peace" or charity. These last most of all depend on the "fellow-working" of man--primarily in the soul receiving them, and secondarily in all who can influence it for good and for evil.

We have here a perfect and exhaustive exposition of the unity of the Church, on which depend the other qualities of "Holiness," "Catholicity," and "Apostolicity" ascribed to it in the Creed. In other passages the essential life of the Church is attributed, now to the revelation of the Father (Matthew 16:17-18), now to the indwelling presence of the Son (Matthew 28:20), now to the gift of the Holy Ghost (Acts 2:38-39). Here all are united in one comprehensive view. The order, however, is natural, not artificial. The exhortation to peace naturally leads to the conception of one Body, animated by the "one Spirit"; next, the remembrance of their calling leads to the "one Lord," who called them to Him in one faith and by one baptism; and all ends in the contemplation of the "one God and Father," who is not only above all and through all His creation, but specially in those who are adopted to a new sonship in Christ. (See John 14:22-23.) In its completeness and depth this passage stands alone. It is interesting to compare and contrast with it the equally celebrated passage occupying the corresponding place in the Colossian Epistle (Colossians 3:1-4), and to gather from this the mingled similarity and difference in the main idea of those two Epistles--the Ephesian Epistle dwelling especially on the unity and regeneration of the whole body, the Colossian Epistle on the sole Headship and Deity of Christ.

(1) Worthy of the vocation wherewith ye are called.--This "being worthy of the Christian calling" may obviously show itself in any of the graces of regenerate humanity, all being features of the image of Christ. Thus in 1Peter 1:15 it expresses itself in "holiness" (as in the frequent phrase "called to be saints"); in Philippians 1:27-30, in steadfastness of faith. But in this passage the especial point which has been dwelt upon in their calling is the fact that they were aliens, helpless and miserable, and that they are now united in one body with the ancient people of God. Hence, naturally, the graces declared to correspond with their calling, so viewed, are the graces of humility and gentleness, teaching them to sink all thought of self in "the unity of the Spirit."

Verses 1-16. - CHURCH PRINCIPLE OF GROWTH AND PROGRESS; THE CHURCH A BODY. Verse 1. - I therefore. Inference not only from last chapter, but the whole Epistle. Paul's interest in the Ephesians led him to a double application of the great subject which he had expounded:

(1) to ask God on their behalf that he would bestow on them the full measure of the blessing to which of his grace they were entitled (Ephesians 3:14-21); and

(2) to entreat them on God's behalf to live in a way befitting their high calling (Ephesians 4:6.). To this second application he proceeds now. The prisoner in the Lord. Not merely "of the Lord," but ἐν, Κυρίῳ, the usual formula for vital communion with Christ, indicating that his captivity was the captivity of a part or member of the Lord. An exhortation from such a prisoner ought to fall with double weight. Beseech you to walk worthy of the calling wherewith ye were called. Their call was to be God's people (comp. Romans 9:25); this not a mere speculative distinction, but one that must have practical form and that must lead to suitable fruit. True grace in the heart must show itself by true goodness in the life. They were not to conceal their religion, not to be ashamed of it, but to avow it and glory in it, and their lives were not to be disgraced by unworthy conduct, but to be brightened and elevated by their relation to Christ.

4:1-6 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 therefore, the prisoner of the Lord, beseech you,.... Or "in the Lord"; that is, for the Lord's sake; See Gill on Ephesians 3:1. Some connect this phrase, "in the Lord", with the following word, "beseech": as if the sense was, that the apostle entreated the believing Ephesians, in the name of the Lord, and for his sake, to take heed to their walk and conversation, that it be as became the calling by grace, and to glory, with which they were called: and this exhortation he enforces from the consideration of the state and condition in which he was, a prisoner, not for any wickedness he had been guilty of, but for the Lord's sake, which seems to be the true sense of the word; and that, if they would not add afflictions to his bonds, as some professors by their walk did, he beseeches them, as an ambassador in bonds, that they would attend to what he was about to say; and the rather, since such doctrines of grace had been made known to them, which have a tendency to promote powerful godliness; and since they were made partakers of such privileges as laid them under the greatest obligation to duty, which were made mention of in the preceding chapters.

That ye walk worthy of the calling wherewith ye are called; by which is meant, not that private and peculiar state and condition of life, that the saints are called to, and in: but that calling, by the grace of God, which is common to them all; and is not a mere outward call by the ministry of the word, with which men may be called, and not be chosen, sanctified, and saved; but that which is internal, and is of special grace, and by the Spirit of God; by whom they are called out of darkness into light, out of bondage into liberty, out of the world, and from the company and conversation of the men of it, into the fellowship of Christ, and his people, to the participation of the grace of Christ here, and to his kingdom and glory hereafter; and which call is powerful, efficacious, yea, irresistible; and being once made is unchangeable, and without repentance, and is holy, high, and heavenly. Now to walk worthy of it, or suitable to it, is to walk as children of the light; to walk in the liberty wherewith Christ and his Spirit make them free; to walk by faith on Christ; and to walk in the ways of God, with Christ, the mark, in their view, and with the staff of promises in their hands; and to walk on constantly, to go forwards and hold out unto the end: for this walking, though it refers to a holy life and conversation, a series of good works, yet it does not suppose that these merit calling; rather the contrary, since these follow upon it; and that is used as an argument to excite unto them: but the phrase is expressive of a fitness, suitableness, and agreeableness of a walk and conversation to such rich grace, and so high an honour conferred on saints.
