Peace Alexei,
[T]he considerations against this assumption [that John Mark, companion of Peter, wrote the gospel of Mark] carry weight. The author obviously has no personal knowledge of Palestinian geography, as the numerous geographical errors show. He writes for Gentile Christians, with sharp polemic against the unbelieving Jews. He does not know the account of the death of the Baptist (6:17 ff) contradicts Palestinian customs. Could a Jewish Christian from Jerusalem miss the fact that 6:35 ff and 8:1 ff are two variants of the same feeding story? The tradition that Mk was written by John Mark is therefore scarcely reliable. The reference to I Pet 5:13 ("The elect of Babylon and my son Mark also greets you") does not account for the tradition, but only the subsequent linking up of the author of Mk with the preaching of Peter. Accordingly, the author of Mk is unknown to us.[1]
First of all, this has no relevance to geography.
Have you lived in 1st Palestine?
You give me this one man's spin on things, but he is not correct.
Let's take the two "contradicting" feeding story accounts.
Mark 8:1
"In those days when there WAS AGAIN a great crowd without anything to eat, He summoned his disciples and said..."
Okay, these aren't contradicting accounts of the same event, but two seperate events.
You should analyze what this man says to see if he's right or not.
