I didn't realize Greek was that widespread.

So in the case of the "Thou art Peter" quote, it is at least plausible that both Jesus and Peter and everyone else in the room would have possessed the required degree of Greek (or koine or interdialect (creole?) or whatever) so everyone would get the joke? And that Peter's parents would have chosen to give him that funny name in the first place?

If true then this seems to suggest a kind of "middle-class" origin for Jesus and the disciples, yes?
