@Setanta,
I haven't seen you address:
1) Josephus' Antiquities book 20 quote of James the brother of Jesus; you said: in essence everything can be redacted. True but then almost everything written during antiquity could have been redacted. We go by the sources we have. In any case, you said there is no contemporary account by a non Christian author, and that is false, or nearly false since Josephus is born in what, 40 CE?
2) the Talmud numerous mentions of Jesus; I said enough on that, it's all up thread. Not a word from you.
3) the parallels that exist between certain Gospel parables and Talmudic passages, such as the speck and the beam in people's eyes, that are indicative of a shared cultural background --> the gospels' sources are largely Jewish - they do not understand the Roman world well but are well aware of the Jewish culture.
4) the argument that a conspiracy is very hard to fathom. Go ahead, tell us WHO invented Jesus, and why, and how they pulled the scam off. Did they also invent Peter? Paul of whom we have letters, John the Baptist, and James the bro mentioned in point 1 above? And how this invention somehow took hold over so many minds so quickly against all odds, and led to a proliferation of diverse and divergent accounts, dozens of gospels and anti gospels over a few centuries...
The alternative scenario -- that there existed a dude called something like Yeshu or Yeshuah at some point in Galilee who blew a mystical fuse and ended up on a cross for it -- seems much more believable to me.
