@Olivier5,
And by the way, if this passage of Ant. book 20 is genuine, one should note that it would only reflect the general Jewish attitude to Jesus at the time, characterized by a mix of indifference, contempt and curiosity, but
never ever by denial.
Now, one would assume that if
someone knew that the whole JC story was a myth, it would be those 1st, 2nd and 3rd century Jews... The story grew up as a total embarrassment for them, so it would have been in their interest to debunk it, had they had the slightest indication that the dude may be a myth, a pagan re-invention of Mithra or something like that.
Yet they didn’t. They never contended that Jesus did not exist… On the contrary, the Talmud has many (disparaging) anecdotes regarding the man, and later on they even wrote their own
anti-gospels, e.g. the Teledoth Yeshu.
I am not saying that the Talmud has historical validity. It was written 1 or 2 centuries after the 4 canonical gospels so is even more hear-say as far as Jesus is concerned. But if there was any merit to the thesis that Jesus was a Pagan invention, that thesis would be relayed in the Talmud.
