Inevitably someone says this to me in this discussion. Yes, I understand that "we all killed him". That is the symbolic meaning of his death. I get it.
But it is useful (because otherwise confusion abounds) to separate that symbolic meaning of his death from the physical act of his death. All of these discussions over who killed Jesus are analyzing the physical act, not the symbolic meaning, so your comment here is irrelevant. And who committed the physical act(s) which contributed to or caused Jesus's death?
Some Romans along with some Jews, 2000 years ago, all of whom are now dead. Like I said.
