I'd settle for an understanding of the cultural context of Second Temple Judaism and the types of cults and sects that existed at that time.
I'd settle for the probability that one of the many "Messianic" pretenders who was executed by the Romans and/or their Jewish collaborators had a group of followers who rationalised their "Messiah's" failure to live up to expectations by turning an execution into a "sacrifice".
I think a good case could be made for the "Teacher of Righteousness" in the DSS being at least one source for the HJ.
I don't know why you think Jesus isn't considered Historically evidenced by just about every Professional Historian in the world who has looked into the subject. Carrier is the only exception that I know of, and he apparently has a low opinion of other Scholars and a very high opinion of himself.
ETA: I don't know why you think anyone would need to invent a failed Messiah, when the Jews were producing plenty of real failed Messiahs from at least the time of Judas The Galilean, up until the fall of the Temple.
I think most scholars wish for a better understanding of first-century culture and its confused mass of sectarian dogmas, claims, fantasies, cults and sects etc, Brainache. Some scholars may pretend otherwise, but documentation for most of that century is scarcer than hen’s teeth, and we actually know very little of early Christian communities and beliefs.
I believe that Ehrman describes first-century Judaism, mentioning the Pharisees, Sadducees, Zealots etc, all in aid of then being able to conclude that Jesus must have been one of the historical apocalyptic messianic pretenders executed by the Romans etc. Well, anything is possible, but it’s not scholarship! Just because one is able to juggle Jesus into a particular, half-plausible historical background, doesn’t prove that he actually existed.
As I see it, the problem with the Teacher of Righteousness resides in the fact that none of the second century religious writings, right up to the canonical gospels’ historized version of Jesus mention him – he might just as well not have existed. In other words, the same problem, with nothing to connect him to the development of Jesus as displayed by extant manuscripts.
I very much doubt that bona fide historians consider Jesus to be historical, as already said. How could they, insofar there doesn’t exist a shred of secular evidence by which to do so?
It’s of course also up to those who posit an historical Jesus to provide the appropriate substantiation. In fact, assuming Jesus did exist, they ought to have it made, a lone, authentic gossipy Roman letter attesting to Jesus existence is sufficient to blow all the opposition, together with centuries of contrary scholarship, out of the water. While we remain bereft of such evidence though, we can only go by the best information and argumentation available, and so far it doesn’t point at any historical person.
One could argue, as many have, that the historical Jesus was but an illiterate, insignificant preacher, one who went unmentioned and unnoticed by all those who were literate, but this hardly tallies with the turmoil and upheaval he’s said to have caused, or someone hailed as the founder of a new world religion.
It’s also hardly a question of needing to invent an imaginary Messiah, even if the Jews had plenty of real failed ones. Merely a matter of drawing the most viable conclusion possible from whatever information is available, obviously.
Gnosticism, a pre-Christian religious movement, seems to me much the best bet, with a Gnostic Jesus the progenitor of the second century’s historized one, narrative theology playing its part.
Doherty places Jesus in a celestial realm, and he maybe right, but according to many in the first century also, the soul or spirit of Jesus had gone below to a place called hades, under or beneath the earth (not that they didn’t believe in heavenly realms as well), and the resurrection here was the calling back of the soul to earth, and its ascension to heaven.
By the way, and I’m only mentioning Ehrman as an illustration of the quality of modern, twenty-first century modern scholarship, with both Doherty and Carrier in fact asserting dates not all that different (nor ignoring countless Wikipedia and other Internet articles offering equally bizarre misinformation), and in that you obviously rate it over those nineteenth century scholars
Vridar’s Neil Godfrey on how the gospels are most commonly dated and why:
“From Bart Ehrman’s Jesus, Interrupted, pp. 144-145:
Even though it is very hard to date the Gospels with precision, most scholars agree on the basic range of dates, for a variety of reasons . . . .
I can say with relative certainty — from his own letters and from Acts — that Paul was writing during the fifties of the common era . . . .
[H]e gives in his own writings absolutely no evidence of knowing about or ever having heard of the existence of any Gospels. From this it can be inferred that the Gospels probably were written after Paul’s day.
It also appears that the Gospel writers know about certain later historical events, such as the destruction of Jerusalem in the year 70 ce . . . That implies that these Gospels were probably written after 70.
There are reasons for thinking Mark was written first, so maybe he wrote around the time of the war with Rome, 70 ce.
If Matthew and Luke both used Mark as a source, they must have been composed after Mark’s Gospel circulated for a time outside its own originating community — say, ten or fifteen years later, in 80 to 85 ce.
John seems to be the most theologically developed Gospel, and so it was probably written later still, nearer the end of the first century, around 90 to 95 ce.”
I won’t even discuss Erhman’s above ‘reasoning’, but there actually doesn’t exist a single bona fide reference to the canonical gospels before the early 170s, and even this is merely an oblique reference to the Gospel of John.
On the previous page it was shown that Justin Martyr, hailing from around the middle of the second century, was still blissfully unaware of them, and the best available evidence suggests that they were in fact written between the years 170 and 180. In 185 or so, even the first church historian Hegesippus hadn’t yet heard of them, still favoring the Gospel of the Hebrews.
I might also note that Mark’s priority, erroneous or not, was first proposed as far back as 1786, and that the ongoing obsession over the ‘Q document’ first began in 1838.
