I think you may misunderstood me, I'm coming from the perspective it could have been a Jesus that wasn't the son of Dammeus not that it could be someone other that Jesus Christ, I don't default to the idea that the text with or without the Christ reference pertains to Jesus Christ.
I don't entertain the idea that the passage is authentic mentioning Jesus Christ of biblical fame.
Why the interpolation is in there in the first place is speculative, but the first rule of fight club is no one talk about fight club, a motif present in Christianity.
hush hush about this and that, leaning towards secrecy and deception.
Speculating more than interpolation but motive is problematic, but it fits the narrative imo.
Personally the myth has manifest a great deal but its truth I find highly questionable given the nature of all the claims that center around the characters, especially Jesus Christ.
I am still kinda on the fence about Jesus Christ historicity, I am open minded but I don't think this jamesian reference is a good match to reality.
Hey listen, it's Christmas. Whilst I don't necessarily buy into it, I am willing to agree with you that the reference to Christ in the James passage is, possibly, an interpolation. There's nothing implausible about that particular suggestion, imo.
I thought you were additionally advancing one of Carrier's 'Plan B' suggestions that both uses of Jesus in the passage were the same guy, which I have a lot of difficulty buying into.
I also don't necessarily think Jesus existed, I just lean slightly in favour, partly because I haven't yet seen what I consider a good enough case. I think trying to get him to be completely ahistorical is a stretch. Most new cults have a charismatic leader. Plus, we have no evidence that they ever felt a need to justify his existence to anyone.
To me, there were two games going on in Early Christianity. One was to try to convince doubters that he really was the messiah. The other was the infighting to be the winning faction. Defending that he even existed wasn't even on the menu, as far as we can reasonably tell.
My money is on Jesus not being what they said about him. 'They' being mostly the Paulines. We don't hear enough about the probably original Jerusalem Jewish followers that most likely, imo, preceded Paul. I have a sneaking suspicion that ol' Jeebus was likely quite a bit more of a militant troublemaker than we think or than the stories would have us believe. As Reza Aslan says, allegedly getting crucified by the Romans is arguably a bit of an obvious clue right from the start.
