Then you acknowledge the historicity of Rabbi Eleazar Hakkapar saying that Jesus claimed to be God? That’s why this rabbi was commenting on Jesus.
I know, I know, with your impossible anti-scientific standard of history, you’ll find some way to wiggle out of this obvious example of an enemy of a historical figure agreeing with the concurring sources about what happened. Not one other historical figure EVER meets your standard. In order to throw out Jesus, you throw out all of history. Irrational. Just like the title implies.
Was he a witness? When did he write, when did it happen?
If they are too far away, he can’t be a witness.
If he was responding to the Christian heresy, he has to state some variation of the Christian position to debunk it. That doesn’t make him an eyewitness, any more than you stating that I don’t accept your pretended eyewitnesses makes you a Christ denier.
