Hi azazyel:
About "Q," I find it sad that so much emphasis is put on a document that we don't have rather than on the ones we do have, including non-canonical documents like the Gospel of Thomas, Hermas, Didache, etc.
We don't really know (even by historical evidences) whether there ever was a single "Q" that served as a common source for the other Gospel accounts. If there was a "Q," it fits into the same category as the following four things:
1. The Kerygma
2. The Testimonia
3. The Logia
4. The Oral Tradition
The Kerygma is the basic oral proclammation of what Christ is believed to have done for us. It is rooted in the the belief that:
1. The age of divine grace and fulfillment of Old Testament prophecies has dawned
2. This age has come through Jesus' death and resurrection
3. The humanity of Jesus has ascended to heaven and been exalted by God as the object of our faith
4. The Holy Spirit has been given through Jesus Christ as a sign of Jesus' authority and as a superior demonstration of God's grace than any written code or law could have been.
5. This age of fulfillment/ divine grace will end when Jesus returns
6. Therefore repent while this age of grace lasts.
You can find these themes laced throughout the Apostles' preaching recorded in the book of Acts and in the Apostles' teaching recorded in the epistles.
The Testimonia refers to common Old Testament prooftexts used in the Kerygma and in early, post-New testament Christian writings.
The Logia ("Sayings") refer to statements Jesus made but that are not preserved in existing traditions. Some very early Christians refer to them. One "Saying" of Jesus that is not in the existing Gospels but did survive is found in Acts 20:35, "It is more blessed to give than to receive."
The Oral Tradition refers to the words of the Apostles and first Christians. Their testimonies were greatly valued as superior to written accounts because of their claim to be witnesses. As in a courtroom setting, eyewitness testimony is invaluable. In historical truths, it is irreplaceable,because historical truths cannot be mathematically verified or repeated. It was only as eyewitnesses began to age and die out that there was a real push to produce/preserve written manuscripts to maintain historical record for what they claimed to have seen.
From these four sources, the Gospels of the New Testament were born. If "Q" exists, it kind of fits in to #2, as would the Gospel of Thomas. But why focus on some supposed "silver bullet" called "Q" when the evidence we already have is more than sufficient to explain the Gosepl accounts, their similarities, and their different perspectives?
It is an academically intriguing concept, but to me changes very little of the historical picture whether it exists or not. If it were ever found and authenticated, then we would have something objective to consider, and I might have to rethink my opinion. That's OK; I've been wrong so many times that being right doesn't matter as much to me as it used to
BTW, I know you were just kind of "tweaking noses," when you mentioned Q. The amazing thing is that, unless I totally misread the intent of your post, the mischievous glee with which you "tweak" shined through. But then that kind of fits your handle, does it not?
