That is Paul's way of describing a church. There were plenty of very imperfect Christians in the community at Ephesus and in the other Asiatic churches to which this letter went. As we know, there were heretics amongst them, and many others to whom the designation of 'holy' seemed inapplicable. But Paul classes them all under one category, and describes the whole body of believing people by these two words, which must always go together if either of them is truly applied, 'saints' and 'faithful.'
Now I think that from this simple designation we may gather two or three very obvious indeed, and very familiar and old-fashioned, but also very important, thoughts.
I. A Christian is a saint.
We are accustomed to confine the word to persons who tower above their brethren in holiness and manifest godliness and devoutness. The New Testament never does anything like that. Some people fancy that nobody can be a saint unless he wears a special uniform of certain conventional sanctities. The New Testament does not take that point of view at all, but regards all true believers in Jesus Christ as being, therein and thereby, saints.
Now, what does it mean by that? The word at bottom simply signifies separation. Whatever is told off from a mass for a specific purpose would be called, if it were a thing, 'holy.' But there is one special kind of separation which makes a person a saint, and that is separation to God, for His uses, in obedience to His commandment, that He may employ the man as He will. So in the Old Testament the designation 'holy' was applied quite as much to the high priest's mitre or to the sacrificial vessels of the Temple as it was to the people who used them. It did not imply originally, and in the first place, moral qualities at all, but simply that this person or that thing belonged to God. But then you cannot belong to God unless you are like Him. There can be no consecration to God except the heart is being purified. So the ordinary meaning of holiness, as moral purity and cleanness from sin, necessarily comes from the original meaning, separation and devotion to the service of God.
Thus we get the whole significance of Christian holiness. We are to belong to God, and to know that we do belong to Him. We are to be separated from the mass of people and things that have no consciousness of ownership and do not yield themselves up to Him for His use. But we cannot belong to Him, and be devoted to His service, unless we are being made day by day pure in heart, and like Him to whom we say that we belong. A human being can only be God's by the surrender of heart and will, and through the continual appropriation into his own character and life, of righteousness and purity like that which belongs to God. Holiness is God's stamp upon a man, His 'mark,' by which He says -- This man belongs to Me. As you write your name in a book, so God writes His name on His property, and the name that He writes is the likeness of His own character.
Note, again, that in God's church there is no aristocracy of sanctity, nor does the name of saint belong only to those who live high above the ordinary tumults of life and the secularities of daily duty. You may be as true a saint in a factory -- ay! and a far truer one -- than in a hermitage. You do not need to cultivate a mediaeval or Roman Catholic type of ascetic piety in order to be called saints. You do not need to be amongst the select few to whom it is given here upon earth, but not given without their own effort, to rise to the highest summits of holy conformity with the divine will. But down amongst all the troubles and difficulties and engrossing occupations of our secular work, you may be living saintly lives; for the one condition of being holy is that we should know whose we are and whom we serve, and we can carry the consciousness of belonging to Him into every corner of the poorest, most crowded, and most distracted life, recognising His presence and seeking to do His will. The saint is the man who says, 'O Lord, truly I am Thy servant; Thou hast loosed my bonds.' Because He has loosed my bonds, the bonds that held me to my sins, He has therein fastened me with far more stringent bonds of love to the sweet and free service of His redeeming love. All His children are His saints.
The Old Testament ritual had one sacrifice which carried this truth in it. It is the first prescribed in the Book of Leviticus, the ceremonial book -- namely, the burnt offering. Its especial meaning was this, that the whole man is to be laid upon God's altar and there consumed in the fire of a divine love. It began with expiation, as all sacrifices must, and on the footing of expiation there followed the transformation, by the fire of God, from gross earthliness into vapour and odour which went up in wreaths of fragrance acceptable to God. So we are to be laid upon the divine altar. So, because we have been accepted in the Beloved, and have received the atonement for our sins through His great sacrifice, we are to be consecrated to His service and, touched by the fire which He sends down, we are to be changed into a sweet odour acceptable to Him as were 'the saints which are in Ephesus.'
II. Further, Christian men are saints because they are believers.
'The saints' and 'the faithful' are not two sets of people, but one. The Apostle starts, as it were, on the surface, and goes down; takes off the uppermost layer and lets us see what is below it; begins with the flowers or the fruit, and then carries us to the root. The saints are saints because they are first of all faithful. 'Faithful' here, of course, does not mean, as it usually does in our ordinary language, 'true' and 'trusty,' 'reliable' and 'keeping our word,' but it means simply 'believing'; having faith, not in the sense of fidelity, but in the sense of trust.
So, then, here is Paul's notion -- and it is not only Paul's notion, it is God's truth -- that the only way by which a man ever comes to realise that he belongs to God, and to yield himself in glad surrender to His uses, and so to become pure and holy like Him whom He loves and aspires to, is by humble faith in Jesus Christ. If you want to talk in theological terminology, sanctification follows upon faith. It is when we believe and trust in Jesus Christ that all the great motives begin to tell upon life and heart, which deliver us from our selfishness, which bind us to God, which make it a joy to do anything for His service, which kindle in our hearts the flame of fructifying and consecrating and transforming love. Faith, the simple reliance of a desperate and therefore trusting heart upon Jesus Christ for all that it needs, is the foundation of the loftiest elevation and attainment of the Christian character. We begin down there that we may set the shining topstone of 'Holiness to the Lord' upon the heaven-pointing summit of our lives.
Note how here Paul sets forth the object of our faith and the blessedness of it. I do not think I am forcing too much meaning into his words when I ask you to notice with what distinct emphasis and intentional fulness he employs the double name of our Lord here to describe the object upon which our faith fixes, 'Faithful in Christ Jesus.' We must lay hold of the Manhood, and we must lay hold of the office. We must rest our soul's salvation on Him as our brother, Jesus who was incarnate in sinful flesh for us; and we must also rest it on Him as God's anointed, who came in human flesh to fulfil the divine loving-kindness and purposes, and in that flesh to die. A faith in a Jesus who was not a Christ would not sanctify; a faith in a Christ who is not Jesus would be impalpable and impotent. We must take the two together, believing and feeling that we lay hold upon a loving Man, 'bone of our bone and flesh of our flesh'; and also upon Him who in His very humanity is the Messenger and Angel of God's covenant; the Christ for whom the way has been being prepared from the beginning, and who has come to fulfil all the purposes of the divine heart.
And notice, too, how there is suggested here also, the blessedness of that faith, inasmuch as it is a faith in Christ. The New Testament speaks in diverse ways about the relation between the believing soul and Jesus Christ. It sometimes speaks of faith as being towards Him, and that suggests the going out of a hand that, as it were, stretches towards what it would lay hold of. It sometimes speaks of faith as being on Him, which suggests the idea of a building on its foundation, or a hand leaning on a support. And it sometimes speaks, as here, of faith being 'in Him,' which suggests the folded wings of the dove that has found its nest, the repose of faith, the quiet rest in the Lord, and 'waiting patiently for Him.' Such trust so directed is the one condition of such tranquillity. Then, again, note a Christian is all that he is because he is 'in Christ.' That phrase 'in Him' is in some sense the keynote of this Epistle to the Ephesians. If you will look over the letter, and pick out all the connections in which the expression 'in Him' occurs, I think you will be astonished to see how rich and full are its uses, and how manifold the blessings of which it is the condition. But the use which Paul makes of it here is just this -- everything in our Christian life depends upon our being rooted and grafted in Jesus. Dear brethren, the main weakness, I believe, of what is called Evangelical Christianity has been that it has not always kept true to the proportionate prominence which the New Testament gives to the two thoughts, 'Christ for us,' and 'Christ in us.' For one sermon that you have heard which has dwelt earnestly and believingly on the thought of the indwelling Christ and the Christian indwelling in Him, you have heard a hundred about the Sacrifice on the Cross for sins, and the great atonement that was made by it. Those of you, who have listened to me from Sunday to Sunday, know that I am not to be charged with minimising or neglecting that truth, but I want to lay upon all your hearts this earnest conviction, that a gospel which throws into enormous prominence 'Christ for us,' and into very small prominence 'Christ in us,' is lame of one foot, is lopsided, untrue to the symmetry and proportion of the Gospel as it is revealed in the New Testament, and will never avail for the nourishment and maturity of Christian souls. 'Christ for us' by all means, and for evermore, but 'Christ in us,' or else He will not be 'for us.'
III. Lastly, a Christian may be a saint, and a believer, and in Christ Jesus, though he is in Ephesus.
Many of you know that probably the words 'in Ephesus' are no part of the original text of this epistle, which was apparently a circular letter, in which the designation of the various churches to which it was sent was left blank, to be filled in with the name of each little community to which Paul's messenger from Rome carried it. The copy from which our text was taken had probably been delivered at Ephesus; and, at any rate, one of the copies would go there. What was Ephesus? Satan's very headquarters and seat in Asia Minor, a focus of idolatry, superstition, wealth, luxury springing from commerce, and moral corruption. 'Great is Diana of the Ephesians.' The books of Ephesus were a synonym for magical books. Many of us know how rotten to the core the society of that great city was. And there, on the dunghill, was this little garden of fragrant and flowering plants. They were 'saints in Christ Jesus,' though they were 'saints in Ephesus.'
Never mind about surroundings. It is possible for us to keep ourselves in the love of God, and in the fellowship of His Son wherever we are, and whatever may lie around us. You and I have too to live in a big, wicked city, and to work out our religion in a society honeycombed with corruption, because of commerce and other influences. Do not let us forget that these people whom Paul called 'saints' and 'faithful' had a harder fight to wage than we have, with less to hearten and strengthen them in it. Only remember if the 'saints in Ephesus' are to be 'in Christ,' they need to keep themselves very straight up. The carbonic acid gas is heavy and goes down to the bottom of the cave, and if a man will walk bolt upright, he will keep his nostrils above it; but if he stoops, he will get down into it. Walk straight up, with your head erect, looking to the Master, and your respiratory organs will be above the poison. If we are to be in Christ when we are in Ephesus, we need to keep ourselves separate and faithful, and to keep ourselves in Christ. If the diver comes out of the diving-bell he is drowned. If he keeps inside its crystal walls he may be on the bottom of the ocean, but he is dry and safe. Keep in the fortress by loyal faith, by humble realisation of His presence, by continual effort, and 'nothing shall by any means harm you,' but 'your lives shall be holy, being hid with Christ in God.'
