Proof of Christianity

[Esquilax]

The comparative religion approach to explanation has a number of fatal flaws. One of these is that it is one thing to follow a religion suggesting that a divinity you never knew came back in some unknowable sense; it's quite another to claim that your mate, who you saw dead, was eating someone else's fish and chips in a new sort of body, right under your nose. The idea of a human coming back from the dead was pretty much unknown before Jesus. In the form of the account, of a new, physical, permanent resurrected body, completely unknown.

Unknown to you, maybe: The greeks had Asclepius, Achilles, Memnon, Alcmene, Castor, Heracles, Melicertes and Aristeas, to name a few, all of which died human and came back immortal. The last of these even has published eyewitness accounts!

Hell, there's three examples of this happening in the Tanakh, so to say it was unthinkable before Jesus is simply ignoring the times that it happened in Judaic lore. You're just wrong, on this point.

Crucially, none of this would account for the whole “Kingdom of God has arrived” thing. The complete change of belief about how Judaism should function. Those bold characters on my first post were intentional...

Except Judaism still exists. What you have is a splinter group of followers; not all that uncommon, for a religion.
