Embellishments in the Gospel of Mark.

[fredd bear]

Q, a historical source?  Q is a hypothetical document proposed 100 years ago but never found.  The only point to hypothesizing it's existence was to rehabilitate the gospels relative inclusions and omissions, to strip the narrative of the supernatural, and present a character closer to our modern liberal sensibilities. 

There is no q manuscript, there is no reference to a q manuscript in antiquity, and if there ever were a q manuscript it's more than a little bit perplexing that no one kept it, considering the giant mound of trash that was kept and endlessly recopied.  

Here's an interesting tidbit.  If there ever were a q, and if the hypothesis about the construction of the other gospels relied on it as envisioned, the authors of that document didn't view jesus as the messiah, they didn't think he had redeemed their sins, they didn't claim that he had risen from the dead.  More a raving wanderer in rags.  The teacher of righteousness, lol.  Even the crucifixion of Some Guy™ is thought to be independent of this hypothetical q.

Any "historical jesus" derived from the q hypothesis will have nothing whatsoever to do with the character of jesus or christ in the new testament.  Instead, it would stand as a rejection of either of those characters being historical in any way.  The nt jesus would not be derived from q, but wholly re-imagined and independently constructed - a few sayings lifted here and there, with the jesus of q having been forgotten in process.  Even the name being a part of that re-imagining.  On top of all of that, the character in q, whomever that was, and if there was a q, wouldn't be on solid ground as a historical figure either.

The Q source, if it existed, is thought to have been more of a collection of things Jesus said rather than another account of the story. If the 2 source hypothesis is true, Q would have been where the sayings were lifted from.

 
Do you mean like The Gospel Of Thomas? Naturally rejected by Christian churches as it contradicts the established Canon, which was conveniently decided with divine guidance.
