Sorry, I wasn't clear. I didn't mean to ask you to prove the non-existence of something. I mean: Do you have any sources for your claim that your theory is the consensus among historians? Because I have always read that even though the first references are from 20 or so years after his death the absolute majority of historians assumes that there was a rabbi fitting that description (one of the many gurus of his time) being executed by the Romans.
Well... As far as I've read, and when I followed some lectures about that period of time, I was told that the honest consensus is that Jesus never existed. But you can't say that too often in public, because once again, you have political correctness. Officially stating that is too awful for Christians, and Christian influence is still very strong amongst our countries. It's denying their religion in its very essence, and we don't want to humiliate our Christian friends, do we?
So when you check the cultural background of almost every "historian" who claims that Yehoshua was nonetheless an historical figure... you will find a Christian or a religious person.
It's exactly the same for historians who deny there could be any real resemblance between Christianity and early Mithran or Sol Invictus mythos. The mere idea that Christianity could have borrowed or aggregated foreign ideas and rituals anywhere else in order to create a synthetic central "Messiah" figure is too awful to endure in our modern times. So they will deny these facts with the last drop of their energy.
But Mithra was born from a virgin during the 25th of december, just like Sol Invictus. To recognize each other, Mithra followers would use the sign of a cross, and to officially initiate a new member, they would symbolically put water on his/her head, and give him/her a piece of bread to eat.
Such coincidences aren't coincidences IMHO.
Now, in 2013, it's still too awful to say this in front of our Christian friends, especially because we don't want to offend them. But who knows, within the next century it might become the official scientific consensus, and our grandchildren might laugh about the religious prudery we still exhibit today.
