Kloppenborg, "On Dispensing with Q?" @ NTS
What Stephen does not mention is that Kloppenborg's article is publicly available, as part of the open access revolution, on Kloppenborg's home page:
John S. Kloppenborg, "On Dispensing with Q? Goodacre on the Relation of Luke to Matthew", New Testament Studies 49/2 (2003) 210-236 [PDF]
Stephen comments on nomenclature and puts his finger on the thing that concerns me with the term Kloppenborg now prefers for the Farrer Theory, "Mark Without Q": it defines someone else's theory by contrasting it with your own, i.e. by what is present (Marcan Priority) and what is absent (Q). Admittedly, I used this title for a while for my web site, as Kloppenborg points out. But my reason for dropping it was that it kept getting misunderstood by cursory users who would ask questions like "But I didn't think Mark had any Q in it anyway; isn't it Matthew and Luke who have Q". It was a strategic decision to try that term, to draw attention to the role played by Marcan Priority so as to contrast it with the Griesbach Theory, which also dispenses with Q but on very different grounds. I was also influenced by E. P. Sanders and M. Davies who used this term in their Studying the Synoptic Gospels. I am pleased, though, that Kloppenborg has dropped the term "Farrer-Goulder", which I think unduly draws attention to Goulder's particular take on the theory, which is convenient for some because it gives them grounds for attacking the theory that are not intrinsic to the theory. I like Stephen's suggested terms like "Mark-Matthew theory" but wonder if now adding yet a fresh designation will only end up with more confusion.
But on to the question of substance raised in Stephen's post, I think he centres in effectively on what to me is the most troubling (or encouraging) element in Kloppenborg's article:
Although Goodacre has presented an interesting case defending the possibility of Luke's direct dependence on Matthew, none of his arguments can be considered sufficiently weighty to displace the alternative scenario, which is at least as plausible, that Luke and Matthew independently drew on Q. (236)What I found interesting about this statement was the assumption here that the two theories, Farrer and Two-Source, were effectively competing on a par. For given that one theory involves an additional, hypothetical document and one does not, I would have thought that the one that does not ought to be accorded priority. This is where I think that Occam's Razor genuinely has a role to play in Synoptic studies. Given that a good case can be made for Luke's use of Matthew, and given that entities should not be multiplied beyond what is necessary, then the Farrer theory should be preferred to the Two-Source Theory.
