The first point, which is fundamental to all the others, is They continued steadfastly in the Apostles' doctrine.'
An earnest desire after fuller knowledge is the basis of all healthy Christian life. We cannot realise, without a great effort, the ignorance of these new converts. Parthians and Medes and Elamites,' and Jews gathered from every corner of the Roman world, they had come up to Jerusalem, and the bulk of them knew no more about Christ and Christianity than what they picked up out of Peter's sermon on the Day of Pentecost. But that was enough to change their hearts and their wills and to lead them to a real faith. And though the contents of their faith were very incomplete, the power of their faith was very great. For there is no necessary connection between the amount believed and the grasp with which it is held. Believing, they were eager for more light to be poured on to their half-seeing eyes. They had no Gospels, they had no written record, they had no means of learning anything about the faith which they were now professing except listening to one or other of the original Eleven, with the addition of any of the other' old disciples '--that is, early disciples --who might perchance have equal claims to be listened to as witnesses from the beginning.' We shall very much misunderstand the meaning of the words here, if we suppose that these novices were dosed with theological instruction, or that the Apostles' doctrine' consisted of such fully developed truths as we find later on in Paul's writings. If you will look at the first sermons that Peter is recorded as having delivered, in the early chapters of the Acts, you will find that he by no means enunciates a definite theology such as he unfolds in his later Epistle. There is no word about the divinity of our Lord Jesus Christ; His designation is Thy holy child Jesus.' There is no word about the atoning nature of Christ's sacrifice; His death is simply the great crime of the Jewish people, and His Resurrection the great divine fact witnessing to the truth of His Messiahship. All that which we now regard, and rightly regard, as the very centre and living focus of divine truth was but beginning to shine out on the Apostles' minds, or rather to gather itself into form, and to shape itself by slow degrees into propositions. The Apostles' teaching '--for' doctrine' does not convey to modern ears what Luke meant by the word--must have been very largely, if not exclusively, of the same kind as is preserved to us in the four Gospels, and especially in the first three of them. The recital to these listeners, to whom it was all so fresh and strange and transcendent, of the story that has become worn and commonplace to us by its familiarity, of Christ in His birth, Christ in His gentleness, Christ in His deeds, Christ in the deep words that the Apostles were only beginning to understand; Christ in His Death, Resurrection, and Ascension--these were the themes on the narration of which this company of three thousand waited with such eagerness.
But, of course, there was necessarily involved in the story a certain amount of what we now call doctrine--that is, theological teaching--because one cannot tell the story of Jesus Christ, as it is told in the four Gospels, without impressing upon the hearers the conviction that His nature was divine and that His death was a sacrifice. Beyond these truths we know not how far the Apostles went. To these, perhaps, they did not at first rise. But whether they did so or no, and although the facts that the hearers were thus eager to receive, and treasured when they received, are the commonplaces of our Sunday-schools, and quite uninteresting to many of us, the spirit which marked these early converts is the spirit that must lie at the foundation of progressive and healthy Christianity in us. The consciousness of our own ignorance, of the great sweep of God's revealed mind and will, the eager desire to fill up the gaps in the circle, and to widen the diameter, of our knowledge, and the consequent steadfastness and persistence of our continuance in the teachings--far fuller and deeper and richer and nobler than were heard in the upper room at Jerusalem by the first three thousand--which, through the divine Spirit and the experience of the Church for nineteen hundred years are available for us, ought to characterise us all.
Now, dear friends, ask yourselves the question very earnestly, Does this desire of fuller Christian knowledge at all mark my Christian character, and does it practically influence my Christian conduct and life? There are thousands of men and women in all our churches who know no more about the rich revelation of God in Jesus Christ than they did on that day long, long ago, when first they began to apprehend that He was the Saviour of their souls. When I sometimes get glimpses into the utter Biblical ignorance of educated members of my own and of other congregations, I am appalled; I do not wonder how we ministers do so little by our preaching, when the minds of the people to whom we speak are so largely in such a chaotic state in reference to Scriptural truth. I believe that there is an intolerance of plain, sober, instructive Christian teaching from the pulpit, which is one of the worst signs of the Christianity of this generation. And I believe that there are a terribly large number of professing Christians, and good people after a fashion, whose Bibles are as clean to-day, except on one or two favourite pages, as they were when they came out of the bookseller's shop years and years ago. You will never be strong Christians, you will never be happy ones, until you make conscience of the study of God's Word and continue steadfastly in the Apostles' teaching.' You may produce plenty of emotional Christianity, and of busy and sometimes fussy work without it, but you will not get depth. I sometimes think that the complaint of the writer of the Epistle to the Hebrews might be turned upside down nowadays. He says: When for the time ye ought to be teachers, ye have need that one teach you again which be the first principles.' Nowadays we might say in Sunday-schools and other places of church work: When for the time ye ought to be learners, you have taken to teaching before you know what you are teaching, and so neither you nor your scholars will profit much.' The vase should be full before you begin to empty it.
Again, there ought to be, and we ought to aim after, an equable temper of mutual brotherhood conquering selfishness.
They continued in the Apostles' doctrine and in fellowship.' Fellowship' here, as I take it, applies to community of feeling. A verse or two afterwards it is applied to community of goods, but we have nothing to do with that subject at present. What is meant is that these three thousand, as was most natural, cut off altogether from their ancient associations, finding themselves at once separated by a great gull from their nation and its hopes and its religion, were driven together as sheep are when wolves are prowling around. And, being individually weak, they held on by one another, so that many weaknesses might make a strength, and glimmering embers raked together might break into a flame.
Now, all these circumstances, or almost all of them, that drove the primitive believers together, are at an end, and the tendencies of this day are rather to drive Christian people apart than to draw them together. Differences of position, occupation, culture, ways of looking at things, views of Christian truth and the like, all come powerfully in to the reinforcement of the natural selfishness which tempts us all, unless the grace of God overcomes it. Although we do not want any hysterical or histrionic presentation of Christian sympathy and brotherhood, we do need--far more than any of us have awakened to the consciousness of the need--for the health of our own souls we need to make definite efforts to cultivate more of that sense of Christian brotherhood with all that hold the same Lord Christ, and to realise this truth: that they and we, however separate, are nearer one another than are we and those nearest to us who do not share in our Christian faith.
I do not dwell upon this point. It is one on which it is easy to gush, and it has got a bad name because there has been so much unreal and sickly talk about it. But if any Christian man will honestly try to cultivate the brotherly feeling which my text suggests, and to which our common relation to Jesus Christ binds us, and will try it in reference to A, B, or C, whom he does not much like, with whose ways he has no kind of sympathy, whom he believes to be a heretic, and who perhaps returns the belief about him with interest, he will find it is a pretty sharp test of his Christian principle. Let us be real, at any rate, and not pretend to have more love than we really, have in our hearts. And let us remember that he that loveth Him that begat, loveth Him also that is begotten of Him.'
