On Papias

Eusebius was wrong. The Presbyters were the Apostles, if you read it closely, and the two attributed with John, were those he personally knew, but that confused scholars for a long time when Eusebius made that error, and it’s identical with the kinds of errors you’re making, here.

And Mark is written out of order. It’s just the way his memory constructed it all together. Yes, the chronology is there, but there's certain details that are indeed out of order, like the man whom Jesus healed with the mat, in John and Mark. It’s not perfectly consistent with all the events.
