=(6) Completeness of the Narrative.=--In treating this subject, Luke had striven, he says, Luke 1:3, first of all for completeness. In his investigations he had followed all things from the beginning. This feature appears plainly in the Gospel. Instead of beginning as Mark does, with the public ministry of Jesus, Luke first gives an account of the birth and infancy, and not content with that, he goes back even to events preceding the birth not only of Jesus, but also of his forerunner.
=(7) Accuracy.=--In the second place, Luke says that he had striven after accuracy. Here again the Gospel justifies the claim of its author. The effort after precision may be seen perhaps especially in such a passage as Luke 3:1,2, where there is an elaborate dating of the beginning of John the Baptist's ministry.
=(8) Orderly Arrangement.=--The effort at orderly arrangement, which forms a third part of the claim which the author makes, was, especially in the Gospel, limited by the material that was at hand. Evidently in Palestine in the early period, the memory of the earthly ministry of Jesus was preserved not in a connected narrative, but in isolated anecdotes. It was impossible, therefore, even for a historian like Luke to maintain a chronological arrangement throughout; where chronological arrangement was impossible he was obliged to be satisfied with an arrangement according to logical affinities. This logical method of arrangement, however, is not resorted to by Luke so much as by Matthew; and for considerable sections of his narrative he was able to gratify his historian's desire for recounting events in the order in which they happened.
=(9) Luke a Historian.=--Detailed examination of the prologue should not be allowed to obscure the outstanding fact that the sum of what Luke here attests is a genuine historical aim and method in the composition of his work. Of course, history in Luke's mind did not exist for its own sake. The Gospel of Luke is not a mere scientific dissertation. On the contrary, the history which is narrated was to the author a thing of supreme value. But it was valuable only because it was true. There is not the slightest evidence that Luke was a bad historian because he was a good Christian. On the contrary, he was a Christian just because he was a historian. In the case of Jesus, knowledge of the real facts is the surest way to adoration.
