Slowly, therefore, progress has been made in the harmonies of the Gospels. But the modern student is able to reproduce the life and words of Jesus as has not been possible since the first century. It is a fourfold portrait of Christ that we get, but the whole is infinitely richer than the picture given by any one of the Four Gospels. The present Harmony aims to put the student in touch with the results of modern scholarly research and to focus attention on the actual story in the Gospels themselves. One may have his own opinion of the Fourth Gospel, but it is needed in a harmony for completeness.

2. Synoptic Criticism

The criticism of the synoptic gospels has been able to reach a broad general conclusion that is likely to stand the test of time. The reason for this happy solution lies in the fact that the processes and results can be tested. It is not mere subjective speculation. Any one who knows how to weigh evidence can compare Mark, Matthew, and Luke in the English, and still better in the Greek. The pages of the present harmony offer proof enough. It is plain as a pikestaff that both our Matthew and Luke used practically all of Mark and followed his general order of events. For this reason Mark has been placed first on the pages where this Gospel appears at all. But another thing is equally clear and that is that both Matthew and Luke had another source in common because they each give practically identical matter for much that is not in Mark at all. This second common source for Matthew and Luke has been called Logia because it is chiefly discourses. It is sometimes referred to as "Q", the first letter of the German word Quelle (source). Unfortunately we do not have the whole of the Logia (Q) before us as in the case of Mark, though we probably do not possess the original ending of Mark in [16:9-20]. But we can at least reproduce what is preserved. Still, just as sometimes either Matthew or Luke made use of Mark, so in the case of the Logia that is probably true. Hence we cannot tell the precise limits of the Logia. Besides, a small part of Mark is not employed by either Matthew or Luke and that may be true of the Logia. But the fact of these two sources for Matthew and Luke seems to be proven.

But there are various other points to be observed. One is that both Matthew and Luke may have had various other sources. Luke tells us ([Luke 1:1-4]) that he made use of "many" such sources, both oral and written. And a large part of Luke does not appear in the other gospels or at least similar events and sayings occur in different environments and times. Hence our solid conclusion must allow freedom and flexibility to the writers in various ways. We can see for ourselves how Matthew and Luke handled both Mark and the Logia, each in his own way and with individual touches of style and purpose.

One other matter calls for attention. Papias is quoted by Eusebius as saying that Matthew wrote in Hebrew (or Aramaic) whereas our present Matthew is in Greek. It is now commonly held that the real Matthew (Levi) wrote the Logia first in Aramaic and that either he or some one else used that with Mark and other sources for our present Gospel of Matthew.

It should be added also that there is a considerable body of evidence for the view that Mark wrote under the influence of Simon Peter and preserves the vividness and freshness of Peter's own style as an eyewitness.

One other result has come. It is increasingly admitted that the Logia was very early, before 50 A.D., and Mark likewise if Luke wrote the Acts while Paul was still alive. Luke's Gospel comes (Acts 1:1) before the Acts. The date of Acts is still in dispute, but the early date (about A.D. 63) is gaining support constantly. The upshot of these centuries of synoptic criticism has brought into sharp outline the facts that now stand out with reasonable clearness. There are many points in dispute still, but we at least know how the synoptic gospels were written, and are reasonably certain of the dates and the authors.

There are many good books on the subject, like Hawkin's Horae Synopticae (second edition), Sanday's Oxford Studies in the Synoptic Problem, Harnack's Sayings of Jesus and his Date of the Synoptic Gospels and Acts. My own views appear in my Commentary on Matthew (Bible for Home and School), Studies in Mark's Gospel, and Luke the Historian in the Light of Research.
