I haven’t tried to shut anything down, I’ve calmly pointed out where you’re wrong for several days and you’re carrying on being wrong whilst acting with such confidence that you’re an expert. In between this you’ve replied with citing the likes of Carrier over Ehrman, which is like listening to Solskjaer’s football philosophy over Pep’s. Now I’ve lost a little patience.
The scholarly community is similar to the scientific one. Theories are banded about and when they’re generally accepted across the board, we can be confident to run with them. Q was presented as a theory not so long ago and the theory was analysed by highly respected secular scholars, who mostly agreed it was a good theory. Matthew and Luke have copied Mark but there are parts of both that are verbatim that aren’t in Mark, so either they’ve got the same source verbally or written, the latter being far more likely as it’s verbatim and this is what we call “Q”.
Mark ends abruptly and there’s obviously some of it missing at the end, I am sceptical about the scripture found years later that conveniently neatly ties in with Matthew and Luke but the story ends pointing towards the resurrection being about to take place or taking place. If you had to fill the blanks as a what-happens-next?, he’d appear out of the tomb. John is far heavier on “Jesus is God” than Mark and Matthew and Luke, surprise surprise sharing sources, are somewhere in between.
Where all agree is that Jesus is the Messiah, started his ministry, performed miracles to prove it, died for humanity’s sins and was the only begotten Son of God. Matthew, Luke and John all have the resurrection and Mark ends abruptly as the story seemingly is about to get to that. I’d say they agree mostly but there are a minority but significant differences.
