In this recent thread , Diogenes and Iscariot began debating the “Q document hypothesis”. I had been under the impression that the vast majority of scholars of early Christianity accepted this hypothesis, but I’s links seem to indicate that anti-Q scholarship is undergoing something of a renaissance. I’d like to continue that discussion here.
For those not familiar with the topic, the Q document hypothesis is an answer to the question, “How did the Gospels come to be written?” The first part of the answer involves noticing that the first 3 Gospels (the “synoptics”) contain much material that is close to word-for-word the same. It’s unlikely bordering on impossible that this much verbal agreement could come from oral tradition; there must have been some common documents that the authors used as sources. The first major result of this line of study was that Mark was the first gospel written, and Matthew and Luke are dependent (either directly or indirectly) on Mark. (As is usual, I am using Matthew, Mark, and Luke as the names of the authors of the gospels. This doesn’t mean, for example, that I believe the person who wrote Matthew was the same Matthew that is mentioned in Matt 9:9. The gospel itself never identifies the author, and the title “The Gospel According to Matthew” was likely added long after the book itself was written. But we have to call the author something, so let’s call him Matthew.) Since the non-Q theories in question accept Mark’s priority, let’s not debate that part here.
The second step was to realize that if you remove the bits of Matt and Luke that look like they were copied from Mark, you are left with quite a few verses in both gospels that still have a high degree of verbal agreement. There are several possible explanations for this fact. Here are a few:
- Matthew used Mark as a source, and Luke used Matthew (and possibly Mark, too). This is the Farrer hypothesis .
- Luke used Mark, and Matthew used Luke. This position doesn’t seem to be held by anyone, so let’s drop it.
- Matt and Luke both used a second written source in addition to Mark. This is the Q document hypothesis .
There are, of course, many other possibilities .
The argument, in brief, for the Q document hypothesis. The main objection to Q is that there are places where Matt and Luke agree with each other, and Mark has a different version.
The big problem for the Farrer hypothesis is to explain why Luke would excise these verses from Matt and collect them in a separate section. If Luke had Matt in front of him, why wouldn’t he just leave those verses in place? If he’s moving things around in Matt, why does he choose to move exactly those verses that don’t come from Mark? This is very hard to understand in the Farrer hypothesis. Goulder takes a shot at explaining away these problems.
Well, got to stop for now. I’m leaning toward the Q hypothesis. Perhaps Iscariot can hold up the anti-Q side.
