[Sidenote: Luke's motive in writing]
The motive which influenced Luke to write is clearly stated. It was to prepare a comprehensive, accurate, and orderly account of the facts in regard to the life of Jesus for his Greek friend Theophilus, who had already been partially instructed in the same. His Gospel confirms the implications of the prologue. It is the longest and most carefully arranged of all the Gospels. The distinctively Jewish ideas or institutions which are prominent in Matthew are omitted or else explained; hence there is nothing which would prove unintelligible to a Greek. The book of the Acts of the Apostles, dedicated to the same patron, is virtually a continuation of the third Gospel, tracing, in a more or less fragmentary manner, the history and growth, of the early Christian Church, and especially the work of Paul.
[Sidenote: Purpose of Mark's Gospel]
Very similar influences called forth the shortest and undoubtedly the oldest of the four Gospels, the book of Mark. The testimony of the contents confirms in general the early statement of Papias and other Christian Fathers that it was written at Rome by John Mark, the disciple and interpreter of the apostle Peter, after the death of his teacher. The absence of many Old Testament quotations, the careful explanation of all Jewish and Palestinian references which would not be intelligible to a foreigner, the presence of certain Latin words, and many other indications, all tend to establish the conclusion that it was written for the Gentile and Jewish Christians, probably at Rome, and that its purpose was simply historical.
[Sidenote: The two-fold purpose of the Gospel of Matthew]
The memoir of Jesus, which we know as the Gospel of Matthew, is from the hand of a Jewish Christian and, as is shown by the amount of material drawn from Mark's Gospel, must be placed at a later date. The great number of quotations from the Old Testament, the interest in tracing the fulfilment of the Messianic predictions, and the distinctively Jewish- Christian point of view and method of interpretation, indicate clearly that he wrote not with Gentile but Jewish Christians in mind. Nevertheless, like that of Mark and Luke, his purpose was primarily to present a faithful and, as far as his sources permitted, detailed picture of the life and teachings of Jesus. His arrangement of his material appears, however, to be logical rather than purely chronological. The different sections and the individual incidents and teachings each contribute to the great argument of the book, namely, that Jesus was the true Messiah of the Jews; that the Jews, since they rejected him, forfeited their birthright; and that his kingdom, fulfilling and inheriting the Old Testament promises, has become a universal kingdom, open to all races and freed from all Jewish bonds. [Footnote: Cf. e.g., x. 5, 6; xv. 24; viii. 11, 12; xii. 38-45; xxi. 42, 43; xxii. 7; xxiii. 13, 36, 38; xxiv. 2; xxviii. 19] This suggests that the First Gospel represents a more mature stage in the thought of the early Church than Mark and Luke.
[Sidenote: Origin of Matthew's Sayings of Jesus]
Its title and the fact that the Church Fathers constantly connect it with Matthew, the publican, and later apostle is explained by the statement of Papias, quoted by Eusebius:
Matthew accordingly composed the oracles in the Hebrew dialect, and each one interpreted them as he was able (H.E., iii. 39). These oracles evidently consisted of a written collection of the sayings of Jesus. Since they were largely if not entirely included in our First Gospel, It was therefore known as The Gospel of Matthew. There is no evidence that the original Matthew's Sayings of Jesus contained definite narrative material. The fact that the First Gospel draws so largely from Mark for its historical data would indicate that this was not supplied by its main source. The Sayings of Jesus was probably the oldest written record of the work of Jesus, for, while oral tradition, easily remembers incidents, disconnected teachings are not so readily preserved by the memory. Their transcendent importance would also furnish a strong incentive to use the pen. It was natural also that, of all the disciples, the ex-customs officer of Capernaum should be the one to undertake this transcendently important task.
