What happened to Matthew's zombies?

[Chas]

It's the ......... "What we do know for sure" ...............part that makes it art.

I'm stating that given the text, that is what we know for sure. In other words what is not speculation but rather derived from the text is what we know for sure.

We know no such thing. We do know that the text was written long after the events, we know that it is not reliable, we know that eyewitness accounts are unreliable, etc.

So, no, we don't know any of that story for sure. Only the gullible and uncritical and delusional say they do.
