Now, these four points which are signalised in this description may well afford us material for consideration. They give us the ideal of a Church's inner life, which in the divine order should precede, and be the basis of, a Church's work in the world. But, while we speak of an ideal for a Church, let us not forget that it is realised only by the lives of individuals being conformed to it. I. 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.
