I'm afraid that with regard to the synoptic gospels both Markan priority and Q as the common sources for Matthew & Luke are "out of vogue" nowadays, but the reasons why folks doubt these common sense solutions are mystifying. It started in the 90s (at least that is when I first noticed it) with posts on Crosstalk2 (XTalk) that seemed intent upon validating the early Christian traditions about the gospel of Matthew having been written in Hebrew (or so says Papias) as the first of the synoptic gospels.Michael BG wrote:Personally I accept that Luke and Matthew used Mark and a common source(s) which is known as Q? Do you not accept this?
I am not sure that “Luke's gospel makes a special theme of the distinctiveness between the lowly Jesus who comes to suffer and die as a human martyr and the exalted Jesus who is rewarded for his suffering witness with glory and exaltation”.
In Mark, Luke and Matthew there are three types of sayings – eschatological ones, suffering ones and “claims of authority” ones (these are problematic as these “authority claims” could refer to Jesus, or Jesus and his followers, or the whole of mankind). It is highly unlikely that early Christianity created all of these sayings. I am not aware of any scholars who believe in an historical Jesus who believe that all Son of Man sayings were created by early Christianity.
By means of tortured logic a few "minor agreements" between Matthew and Luke against the text of Mark have overturned all that common material between Mark and Matthew & Luke, and the Q hypothesis to explain the other common materials in Matthew and Luke that are not in Mark, to get Matthew being (wait for it) the first written synoptic gospel, from which was derived Luke, and Mark becomes a rump gospel cut down from Matthew. If one were to ask me, I think that this alternate universe still has lots of loose ends to tie up, and ends up being an even more complicated solution than what it "improves".
Offhand I do not know where Neil stands on this. To me the Matthian priority hypothesis is a fad, like Jesus Christos being derived from a Marcionite Chestos is a fad. Fad fad fad fad ... and Fad is bad bad bad ...
