Re: Q and Papias

<<The earliest
historical source (Papias) knows nothing of it.>>

Papias IMHO does talk about Q. He says that Matthew wrote a gospel in Aramaic
and that Luke translated it into Greek. I think that this was Q. Later
someone besides Matthew wrote the gospel that bears his name. It is obvious
that there is a literary relationship between Matt and Luke. Whether this is
Q or whether this is an abridgement of one gospel writer by another will
never be proven.
