> Crossan is wrong.
I can certainly agree that Crossan used a bit of hyperbole to make his point, but I still consider his point to be valid: the crucifixion of Jesus is authentic history.
> Josephus
Antiquities 18.33: "He was Christ, and when Pilate, at the suggesting of the principal men among us, had condemned him to the cross..."
> Tacitus
Annals XV 44: "The founder of the sect, Christus, had been put to death by the governor of Judea, Pontius Pilate, when Tiberius was emperor."
> You totally missed OP's point. God has the power to do anything, including go through a crucifixion without suffering no matter how much his avatar is brutalized.
This is just the point: God does not have the power to do anything. That's not what omnipotence means.
* God can't do what is logically absurd or contradictory (like make a square circle or a married bachelor)
* God can't act contrary to his nature. He can only be self-consistent and not self-contradictory.
* God cannot fail to do what he has promised. That would mean God is flawed.
* God cannot change the past. Time by definition is linear in one direction only.
Since by his own testimony Jesus came to suffer for the sins of humanity (Lk. 9.22 et al.), we can also assume he didn't opt out of the pain part, which means all the evidence we have (extrabibilical corroboration of his suffering in crucifixion, and biblical evidence of his suffering in crucifixion) leads us to the conclusion that he didn't go through a crucifixion without suffering.
