I turn now to set side by side with this vague, general, outside name the more specific and interior names--if I may so call them--by which Christ's followers at first knew themselves.
The world said, You are Christ's men'; and the names which were self-imposed and are now to be considered might be taken as being the Church's explanation of what the world was fumbling at when it so called them. There are four of them: of course, I can only just touch on them.
(a) The first is in this verse--disciples: The others are believers, saints, brethren. These four are the Church's own christening of itself; its explanation and expansion, its deepening and heightening, of the vague name given by the world.
As to the first, disciples, any concordance will show that the name was employed almost exclusively during the time of Christ's life upon earth. It is the only name for Christ's followers in the Gospels; it occurs also, mingled with others, in the Acts of the Apostles, and it never occurs thereafter.
The name disciple,' then, carries us back to the historical beginning of the whole matter, when Jesus was looked upon as a Rabbi having followers called disciples; just as were John the Baptist and his followers, Gamaliel and his school, or Socrates and his. It sets forth Christ as being the Teacher, and His followers as being His adherents, His scholars, who learned at His feet.
Now that is always true. We are Christ's scholars quite as much as were the men who heard and saw with their eyes and handled with their hands, of the Word of Life. Not by words only, but by gracious deeds and fair, spotless life, He taught them and us and all men to the end of time, our highest knowledge of God of whom He is the final revelation, our best knowledge of what men should and shall be by His perfect life in which is contained all morality, our only knowledge of that future in that He has died and is risen and lives to help and still to teach. He teaches us still by the record of His life, and by the living influence of that Spirit whom He sends forth to guide us into all truth. He is the Teacher, the only Teacher, the Teacher for all men, the Teacher of all truth, the Teacher for evermore. He speaks from Heaven. Let us give heed to His voice.
But that Name is not enough to tell all that He is to us, or we to Him, and so after He had passed from earth it unconsciously and gradually dropped out of use by the disciples, as they felt a deepened bond uniting them to Him who was not only their Teacher of the Truth which was Himself, but was their Sacrifice and Advocate with the Father. And for all who hold the, as I believe, essentially imperfect conception of Jesus Christ as being mainly a Teacher, either by word or by pattern; whether it be put into the old form or into the modern form of regarding Him as the Ideal and Perfect Man, it seems to me a fact well worthy of consideration, that the name of disciple and the relation expressed by it were speedily felt by the Christian Church to be inadequate as a representation of the bond that knit them to Him. He is our Teacher, we His scholars. He is more than that, and a more sacred bond unites us to Him. As our Master we owe Him absolute submission. When He speaks, we have to accept His dictum. What He says is truth, pure and entire. His utterance is the last word upon any subject that He touches, it is the ultimate appeal, and the Judge that ends the strife. We owe Him submission, an open eye for all new truth, constant docility, as conscious of our own imperfections, and a confident expectation that He will bless us continuously with high and as yet unknown truths that come from His inexhaustible stores of wisdom and knowledge.
(b) Teacher and scholars move in a region which, though it be important, is not the central one. And the word that was needed next to express what the early Church felt Christ was to them, and they to Him, lifts us into a higher atmosphere altogether,--believers; they who are exercising not merely intellectual submission to the dicta of the Teacher, but who are exercising living trust in the person of the Redeemer. The belief which is faith is altogether a higher thing than its first stage, which is the belief of the understanding. There is in it the moral element of trust. We believe a truth, we trust a Person; and the trust which we are to exercise in Jesus Christ, and which knits us to Him, is our trust in Him, not in any character that we may choose to ascribe to Him, but in the character in which He is revealed in the New Testament--Redeemer, Saviour, Manifest God; and therefore, the Infinite Friend and Helper of our souls.
That trust, my brethren, is the one bond that binds men to God, and the one thing that makes us Christ's men. Apart from it, we may be very near Him, but we are not joined to Him. By it, and by it alone, the union is completed, and His power and His grace flow into our spirits. Are you, not merely a Christian,' in the world's notion, being bound in some vague way to Jesus Christ, but are you a Christian in the sense of trusting your soul's salvation to Him?
(c) Then, still further, there is another name--saints: It has suffered perhaps more at the hands both of the world and of the Church than any other. It has been taken by the latter and restricted to the dead, and further restricted to those who excel, according to the fantastic, ascetic standard of mediaeval Christianity. It has suffered from the world in that it has been used with a certain bitter emphasis of resentment at the claim of superior purity supposed to be implied in it, and so has come to mean on the world's lips one who pretends to be better than other people and whose actions contradict his claim. But the name belongs to all Christ's followers. It makes no claim to special purity, for the central idea of the word saint' is not purity. Holiness, which is the English for the Latinised sanctity,' holiness which is attributed in the Old Testament to God first, to men only secondarily, does not primarily mean purity, but separation. God is holy, inasmuch as by that whole majestic character of His, He is lifted above all bounds of creatural limitations, as well as above man's sin. A sacrifice, the Sabbath, a city, a priest's garment, a mitre--all these things are holy,' not when they are pure, but when they are devoted to Him. And men are holy, not because they are clean, but because by free self-surrender they have consecrated themselves to Him.
Holiness is consecration, that is to say, holiness is giving myself up to Him to do what He will with. I am holy' is not the declaration of my estimate I am pure,' but the declaration of the fact I am thine, O Lord.' So the New Testament idea of saint has in it these elements--consecration, consecration resting on faith in Christ, and consecration leading to separation from the world and its sin. And that glad yielding of oneself to God, as wooed by His mercies, and thereby drawn away from communion with our evil surroundings and from submission to our evil selves, must be a part of the experience of every true Christian. All His people are saints, not as being pure, but as being given up to Him, in union with whom alone will the cleansing powers flow into their lives and clothe them with the righteousness of saints.' Have you thus consecrated yourself to God?
(d) The last name is' brethren '--a name which has been much maltreated both by the insincerity of the Church, and by the sarcasm of the world. It has been an unreal appellation which has meant nothing and been meant to mean nothing, so that the world has said that our' brethren' signified a good deal less than their brothers.' "Tis true, tis pity; pity tis, tis true.'
But what I ask you to notice is that the main thing about that name brethren' is not the relation of the brethren to one another, but their common relation to their Father.
When we call ourselves as Christian people' brethren,' we mean first this: that we are the possessors of a supernatural life, which has come from one Father, and which has set us in altogether new relations to one another, and to the world round about us. Do you believe that if you have any of that new life which comes through faith in Jesus Christ, then you are the brethren of all those that possess the same?
As society becomes more complicated, as Christian people grow unlike each other in education, in social position, in occupation, in their general outlook into the world, it is more and more difficult to feel what is nevertheless true: that any two Christian people, however unlike each other, are nearer each other in the very roots of their nature, than a Christian and a non-Christian, however like each other. It is difficult to feel that, and it is getting more and more difficult, but for all that it is a fact.
And now I wish to ask you, Christian men and women, whether you feel more at home with people who love Jesus Christ--as you say that you love Him --or whether you like better to be with people who do not?
There are some of you who choose your intimate associates, whom you ask to your homes and introduce to your children as desirable companions, with no reference at all to their religious character. The duties of your position, of course, oblige each of you to be much among people who do not share your faith, and it is cowardly and wrong to shrink from the necessity. But for Christian people to make choice of heart friends, or close intimates, among those who have no sympathy with their professed belief about, and love to, Jesus Christ, does not say much for the depth and reality of their religion. A man is known by the company he keeps, and if your friends are picked out for other reasons, and their religion is no part of their attraction, it is not an unfair conclusion that there are other things for which you care more than you do for faith in Jesus Christ and love to Him. If you deeply feel the bond that knits you to Christ, and really live near to Him, you will be near to your brethren. You will feel that blood is thicker than water,' and however like you may be to irreligious people in many things, you will feel that the deepest bond of all knits you to the poorest, the most ignorant, the most unlike you in social position; ay! and the most unlike you in theological opinion, who love the Lord Jesus Christ in sincerity.
Now that is the sum of the whole matter. And my last word to you is this: Do not you be contented with the world's vague notions of what makes Christ's man. I do not ask you if you are Christians; plenty of you would say: Oh yes! of course! Is not this a Christian country? Was not I christened when I was a child? Are we not all members of the Church of England by virtue of our birth? Yes! of course I am!'
I do not ask you that; I do not ask you anything; but I pray you to ask yourselves these four questions: Am I Christ's scholar? Am I believing on Him? Am I consecrated to Him? Am I the possessor of a new life from Him? And never give yourselves rest until you can say humbly and yet confidently, Yes! thank God, I am!
