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.
