No, Christianity was founded after his death by Paul and some of his other followers. We seem to talking about two people here, Jesus the human being and the divine Jesus apotheosized by his followers after his death. I find the former plausible and the latter implausible.
Ah,
but that would would qualify as
Christ Myth theory per John Robertson (1900), Herbert George Wood (1934), International Standard Bible Encyclopedia (1982, 1995), and Bart Ehrman (2012). Though it would an ahistorical Jesus and NOT Christ Myth per Carrier's definitions.
And
that is the problem.
The Christ myth is MORE then simply Jesus didn't exist as a historical person:
"While all Freethinkers are agreed that
the Christ of the New Testament is a myth they are not, as we have seen, and perhaps never will be, fully agreed as to the nature of this myth. Some believe that he is a historical myth; others that he is a pure myth." - Remsburg 1909
"But the sociological fashion reflected in the rise of Formgeschichte leads colour to
Christ-myth theories and indeed to all theories which regard Jesus as an historical but insignificant figure." - Wood, Herbert George (1934) Christianity and the nature of history, MacMillan (New York, Cambridge, [Eng.] : The University Press pg 40
"The myth theory is not concerned to deny such a possibility [that Jesus existed as a human being].
What the myth theory denies is that Christianity can be traced to a personal founder who taught as reported in the Gospels and was put to death in the circumstances there recorded" - Robertson, Archibald (1946)
Jesus: Myth or History? regarding John Robertson's 1900 work
"This view (Christ Myth theory) states that
the story of [ie NOT the man himself] Jesus is a piece of mythology, possessing no more substantial claims to historical fact than the old Greek or Norse stories of gods and heroes..." - Geoffrey W. Bromiley (ed)
International Standard Bible Encyclopedia: E-J 1982, 1995
"[The Christ myth] is the theory that
no historical Jesus worthy of the name existed, that Christianity began with a belief in a spiritual, mythical figure, that the Gospels are essentially allegory and fiction, and that no single identifiable person lay at the root of the Galilean preaching tradition." In simpler terms, the historical Jesus did not exist.
Or if he did, he had virtually nothing to do with the founding of Christianity." - Ehrman, Bart (2012)
Did Jesus Exist Harper Collins, , p. 12)
As I have pointed out now, as back in the last year of the 19th century, there are difference definitions of Christ Myth theory which do NOT exclude a historical Jesus.
