The difference in significance between “Christ” or “Christ Jesus” and “the Christ” in such a sentence as this, is not unlike the difference between “Queen Victoria” and “the Queen.” The latter phrase brings Her Majesty before us in the grandeur and splendour of her Queenship. We think of her vast dominion, of her line of royal and famous ancestry, of her beneficent and memorable reign. So, to know the Christ is to apprehend Him in the height of His Godhead, in the breadth of His humanity, in the plenitude of His nature and His powers. And this is the object to which the teaching and the prayers of St Paul for the Churches at the present time are directed. Understanding in this larger sense the indwelling of the Christ for which he prays, we see how naturally his supplication expands into the “height and depth” of the ensuing verse.

But however large the mental conception of Christ that St Paul desires to impart to us, it is to be grasped “through faith.” All real understanding and appropriation of Christ, the simplest and the most advanced, come by this channel,—through the faith of the heart in which knowledge, will and feeling blend in that one act of trustful apprehension of the truth concerning Jesus Christ by which the soul commits itself to Him.

How much is contained in this petition of the apostle that we need to ask for ourselves, Christ Jesus dwells now as then in the hearts of all who love Him. But how little do we know our heavenly Guest! how poor a Christ is ours, compared to the Christ of Paul’s experience! how slight and empty a word is His name to multitudes of those who bear it! If men have once attained a sense of His salvation, and are satisfied of their interest in His atonement and their right to hope for eternal life through Him, their minds are at rest. They have accepted Christ and received what He has to give them; they turn their attention to other things. They do not love Christ enough to study Him. They have other mental interests,—scientific, literary, political or industrial; but the knowledge of Christ has no intellectual attraction for them. With St Paul’s passionate ardour, the ceaseless craving of his mind to “know Him,” these complacent believers have no sympathy whatever. This, they think, belongs only to a few, to men of metaphysical bias or of religious genius like the great apostle. Theology is regarded as a subject for specialists. The laity, with a lamentable and disastrous neglect, leave the study of Christian doctrine to the ministry. The Christ cannot take His due place in His people’s heart, He will not reveal to them the wealth of His glory, while they know so little and care to know so little of Him. How many can be found, outside the ranks of the ordained, that make a sacrifice of other favourite pursuits to meditate on Christ? what prosperous merchant, what active man of affairs is there who will spare an hour each day from his other gains “for the excellency of the knowledge of Christ Jesus my Lord”?—“If at the present time the religious life of the Church is languid, and if in its enterprises there is little of audacity and vehemence, a partial explanation is to be found in that decline of intellectual interest in the contents of the Christian Faith which has characterized the last hundred or hundred and fifty years of our history.”[96]

It is a knowledge that when pursued grows upon the mind without limit. St Paul, who knew so much, for that reason felt that all he had attained was but in the bud and beginning. “The Christ” is a subject infinite as nature, large and wide as history. With our enlarged apprehension of Him, the heart enlarges in capacity and moral power. Not unfrequently, the study of Christ in Scripture and experience gives to unlettered men, to men whose mind before their conversion was dull and uninformed, an intellectual quality, a power of discernment and apprehension that trained scholars might envy. By such thoughtful, constant fellowship with Him the vigour of spirit and courage in affliction are sustained, that the apostle first asked from God on behalf of his anxious Gentile friends.

III. The prayers now offered might suffice, if St Paul were concerned only for the individual needs of those to whom he writes and their personal advancement in the new life. But it is otherwise. The Church fills his mind. Its lofty claims at every turn he has pressed on our attention. This is God’s holy temple and the habitation of His Spirit; it is the body in which Christ dwells, the bride that He has chosen. The Church is the object that draws the eyes of heaven; through it the angelic powers are learning undreamed-of lessons of God’s wisdom. Round this centre the apostle’s intercession must needs revolve. When he asks for his readers added strength of heart and a richer fellowship with Christ, it is in order that they may be the better able to enter into the Church’s life and to apprehend God’s great designs for mankind.

This object so much absorbs the writer’s thoughts and has been so constantly in view from the outset, that it does not occur to him, in verse 18, to say precisely what that is whose “breadth and length and height and depth” the readers are to measure. The vast building stands before us and needs not to be named; we have only not to look away from it, not to forget what we have been reading all this time. It is God’s plan for the world in Christ; it is the purpose of the ages realized in the building of His Church. This conception was so impressive to the original readers and has held their attention so closely since the apostle unfolded it in the course of the second chapter, that they would have no difficulty in supplying the ellipsis which has given so much trouble to the commentators since.

If we are asked to interpret the four several magnitudes that are assigned to this building of God, we may say with Hofmann[97]: “It stretches wide over all the world of the nations, east and west. In its length, it reaches through all time unto the end of things. In depth, it penetrates to the region where the faithful sleep in death [comp. iv. 9]. And it rises to heaven’s height, where Christ lives.” In the like strain Bernardine à Piconio, most genial and spiritual of Romanist interpreters: “Wide as the furthest limits of the inhabited world, long as the ages of eternity through which God’s love to His people will endure, deep as the abyss of misery and ruin from which He has raised us, high as the throne of Christ in the heavens where He has placed us.” Such is the commonwealth to which we belong, such the dimensions of this city of God built on the foundation of the apostles,—“that lieth four-square.”

Do we not need to be strong—to “gain full strength,” as the apostle prays, in order to grasp in its substance and import this immense revelation and to handle it with practical effect? Narrowness is feebleness. The greatness of the Church, as God designed it, matches the greatness of the Christ Himself. It needs a firm spiritual faith, a far-seeing intelligence, and a charity broad as the love of Christ to comprehend this mystery. From many believing eyes it is still hidden. Alas for our cold hearts, our weak and partial judgements! alas for the materialism that infects our Church theories, and that limits God’s free grace and the sovereign action of His Spirit to visible channels and ministrations “wrought by hand.” Those who call themselves Churchmen and Catholics contradict the titles they boast when they bar out their loyal Christian brethren from the covenant rights of faith, when they deny churchly standing to communities with a love to Christ as warm and fruitful in good works, a gospel as pure and saving, a discipline at least as faithful as their own. Who are we that we dare to forbid those who are doing mighty works in the name of Christ, because they follow not with us? When we are fain to pull down every building of God that does not square with our own ecclesiastical plans, we do not apprehend “what is the breadth!”

We draw close about us the walls of Christ’s wide house, as if to confine Him in our single chamber. We call our particular communion “the Church,” and the rest “the sects”; and disfranchise, so far as our word and judgement go, a multitude of Christ’s freemen and God’s elect, our fellow-citizens in the New Jerusalem—saints, some of them, whose feet we well might deem ourselves unworthy to wash. A Church theory that leads to such results as these, that condemns Nonconformists to be strangers in the House of God, is self-condemned. It will perish of its own chillness and formalism. Happily, many of those who hold the doctrine of exclusive Roman or Anglican, or Baptist or Presbyterian legitimacy, are in feeling and practice more catholic than in their creed.

“With all the saints” the Asian Christians are called to enter into St Paul’s wider view of God’s work in the world. For this is a collective idea, to be shared by many minds and that should sway all Christian hearts at once. It is the collective aim of Christianity that St Paul wants his readers to understand, its mission to save humanity and to reconstruct the world for a temple of God. This is a calling for all the saints; but only for saints,—for men devoted to God and renewed by His Spirit. It was “revealed to His holy apostles and prophets” (ver. 5); and it needs men of the same quality for its bearers and interpreters.
