The first thing that strikes me in connection with these words is, how deep and real they show that new bond of Christian love to have been.

A little incident of this sort is more impressive than any amount of mere talk about the uniting influence of the Gospel. Here we get a glimpse of the power in actual operation in a man's heart, and if we think of all that this simple greeting presupposes and implies, and of all that had to be overcome before it could have been sent, we may well see in it the sign of the greatest revolution that was ever wrought in men's relations to one another, Quartus was an inhabitant of Corinth, from which city this letter was written. His Roman name may indicate Roman descent, but of that we cannot be sure. Just as probably he may have been a Greek by birth, and so have had to stretch his hand across a deep crevasse of national antipathy, in order to clasp the hands of his brethren in the great city. There was little love lost between Rome, the rough imperious conqueror, and Corinth, prostrate and yet restive under her bonds, and nourishing remembrances of a freedom which Rome had crushed, and of a culture that Rome haltingly followed.

And how many other deep gulfs of separation had to be bridged before that Christian sense of oneness could be felt! It is impossible for us to throw ourselves completely back to the condition of things which the Gospel found. The world then was like some great field of cooled lava on the slopes of a volcano, all broken up by a labyrinth of clefts and cracks, at the bottom of which one can see the flicker of sulphurous flames. Great gulfs of national hatred, of fierce enmities of race, language, and religion; wide separations of social condition, far profounder than anything of the sort which we know, split mankind into fragments. On the one side was the freeman, on the other, the slave; on the one side, the Gentile, on the other, the Jew; on the one side, the insolence and hard-handedness of Roman rule, on the other, the impotent, and therefore envenomed, hatred of conquered peoples.

And all this fabric, full of active repulsions and disintegrating forces, was bound together into an artificial and unreal unity by the iron clamp of Rome's power, holding up the bulging walls that were ready to fall—the unity of the slave-gang manacled together for easier driving. Into this hideous condition of things the Gospel comes, and silently flings its clasping tendrils over the wide gaps, and binds the crumbling structure of human society with a new bond, real and living. We know well enough that that was so, but we are helped to apprehend it by seeing, as it were, the very process going on before our eyes, in this message from ‘Quartus a brother.’

It reminds us that the very notion of humanity, and of the brotherhood of man, is purely Christian. A world-embracing society, held together by love, was not dreamt of before the Gospel came; and since the Gospel came it is more than a dream. If you wrench away the idea from its foundation, as people do who talk about fraternity, and seek to bring it to pass without Christ, it is a mere piece of Utopian sentiment—a fine dream. But in Christianity it worked. It works imperfectly enough, God knows. Still there is some reality in it, and some power. The Gospel first of all produced the thing and the practice, and then the theory came afterwards. The Church did not talk much about the brotherhood of man, or the unity of the race; but simply ignored all distinctions, and gathered into the fold the slave and his master, the Roman and his subject, fair-haired Goths and swarthy Arabians, the worshippers of Odin and of Zeus, the Jew and the Gentile. That actual unity, utterly irrespective of all distinctions, which came naturally in the train of the Gospel, was the first attempt to realise the oneness of the race, and first taught the world that all men were brethren.

And before this simple word of greeting could have been sent, and the unknown man in Corinth felt love to a company of unknown men in Rome, some profound new impulse must have been given to the world; something altogether unlike any of the forces hitherto in existence. What was that? What should it be but the story of One who gave Himself for the whole world, who binds men into a unity because of His common relation to them all, and through whom the great proclamation can be made: ‘There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female, for ye are all one in Christ Jesus.’ Brother Quartus’ message, like some tiny flower above-ground which tells of a spreading root beneath, is a modest witness to that mighty revolution, and presupposes the preaching of a Saviour in whom he and his unseen friends in Rome are one.

So let us learn not to confine our sympathy and the play of our Christian affection within the limits of our personal knowledge. We must go further a-field than that. Like this man, let us sometimes send our thoughts across mountains and seas. He knew nobody in the Roman Church, and nobody knew him, but he wished to stretch out his hand to them, and to feel, as it were, the pressure of their fingers in his palm. That is a pattern for us.

Let me suggest another thing. Quartus was a Corinthian. The Corinthian Church was remarkable for its quarrellings and dissensions. One said, ‘I am of Paul, and another, I of Apollos, and I of Cephas, and I of Christ.’ I wonder if our friend Quartus belonged to any of these parties? There is nothing more likely than that he had a much warmer glow of Christian love to the brethren over there in Rome than to those who sat on the same bench with him in the upper room at Corinth. For you know that sometimes it is true about people, as well as about scenery, that ‘distance lends enchantment to the view.’ A great many of us have much keener sympathies with ‘brethren’ who are well out of our reach, and whose peculiarities do not jar against ours, than with those who are nearest. I do not say Quartus was one of these, but he may very well have been one of the wranglers in Corinth who found it much easier to love his brother whom he had not seen than his brother whom he had seen. So take the hint, if you need it. Do not let your Christian love go wandering away abroad only, but keep some for home consumption.

Again, how simply, and with what unconscious beauty, the deep reason for our Christian unity is given in that one word, a ‘Brother.’ As if he had said, Never mind telling them anything about what I am, what place I hold, or what I do. Tell them I am a brother, that will be enough. It is the only name by which I care to be known; it is the name which explains my love to them.

We are brethren because we are sons of one Father. So that favourite name, by which the early Christians knew each other, rested upon and proclaimed the deep truth that they knew themselves to be all partakers of a common life derived from one Parent. When they said they were brethren, they implied, ‘We have been born again by the word of God, which liveth and abideth for ever.’ The great Christian truth of regeneration, the communication of a divine life from God the Father, through Christ the Son, by the Holy Spirit, is the foundation of Christian brotherhood. So the name is no mere piece of effusive sentiment, but expresses a profound fact. ‘To as many as received Him, to them gave He power to become the sons of God,’ and therein to become the brethren of all His sons.
