Yes, you can. Instead of simply telling him you can't speak to him, speak to him.
I mean, whenever any one of you two is posting in a thread about this topic, your posts are both compelling and entertaining. But as soon as both of you are there, you turtle up. What's up with that ? Are you allergic to each other ?
I must admit that I AM getting allergic to being told I'm a CT-er if I don't trust some authority. If an authority, or anyone else, is right -- and they might be -- then it's by virtue of showing the evidence to support their conclusion, not by virtue of anything else, being an authority included. Hence, if it's that unassailable, it should be quite easy to just present whatever argument makes that conclusion so watertight. NOT just insist that one can't disagree with an authority. It doesn't work that way in any scientific domain.
Well, you know like Q is a previous version for Luke and Matthew, supposedly.
Actually, it's just SOME source that made its way into both Matthew and Luke (as the accepted chronological order goes). We don't even know it's not just Matthew (as Carrier and a few others seem to favour.) In any case, even if it's earlier than Matthew, which is a big IF, we don't know if it's also earlier than Mark, much less that it's earlier than Paul.
Really, nobody saw Q, it's not mentioned by any church father, it contains (in as much as we can reconstruct it from Matthew and Luke) no references to identifiable historical events that might help date it, etc. We don't know who wrote it, when, or what else was in it.
Even the points usually made about it, like, "Q has no mention of the crucifixion", are actually wild and unsupportable guesses. The parts we reconstructed have no mention of that, but we don't know what was in the rest of it, or why wasn't it included. E.g., whether it actually had no crucifixion or resurrection, or Matthew and Luke just didn't feel like copying some redundant parts that were already in Mark anyway.
You think Paul was the originator of Christianity ? Then, if he didn't have a real vision from god, then he must've gotten that from somewhere.
... in as much as one can say Charles Manson must have gotten his racial revolution ideas from SOMEWHERE. In his case, though, it was just delusions of reference in Beatles songs. Seriously, he thought that Beatles songs contain cryptic messages to him, about something they never actually sung about. That's what schizophrenia will do to ya. Whether or not that's the case with Paul too, well, that's a good question.
Which is another reason to doubt Paul's message, once one realizes that he still has conversations with ghostly Jesus and describes half a dozen textbook paranoid schizophrenia symptoms in himself, including, yes, delusions of reference, as in finding messages to/about himself in OT fragments about something completely unrelated. Finding messages to them in something completely unrelated is what those people do. James could have basically said, "get the hell out of here" or "who the hell is this guy and what does he want from me?", and Paul could have understood that it means "go preach the gospel to the gentiles." Or whatever.
I mean, just like one can say that Paul wouldn't make up X, Y and Z, one can say that Charles Manson wouldn't make up messages from the Beatles. And indeed, he didn't. His sick brain just twisted something else into a hidden message to him.
So, anyway, maybe he did talk to some guys called Peter and James from some pre-existing church, and improbably enough, so accurate was the version from his hallucination, that those had nothing to correct or add to it. (Yeah right

) Or maybe he is lying about it. Or maybe it's just one of his delusions. We don't really know.
