A little bit about the book of Mark and it's author...

While there is no hard evidence that John Mark wrote the book of Mark, there are some very good reasons to believe he did.
       1) The conclusions of early church historians Papias and Eusebiaus of Caesarea
       2) The relationship between Peter and Mark's writings. (it seems that Mark was Peters interpreter)

• Written by John Mark. John was his Jewish name, Mark was his Roman name.
• Mark is the most often referred to in the Bible of the synoptic gospel writers.
• Barnabas (Marks cousin) and Saul (aka. Paul) invited Mark to join them on their first missionary trip from Cyprus to Perga
• Mark left the team in Perga and returned to Jerusalem. The reason for this is unclear, but it must not have been on the best of terms. It seems like this is reflected in Pauls later reluctance to include Mark on their second mission trip.
• Barnabas wanted Mark to come on their second mission trip. This led Paul and Barnabas to part ways.
• Barnabas and Mark went to Cyprus
• At some point Paul and Mark made amends and Mark became like a "son" to Paul.
• It is believed that Mark could be the young man mentioned in Mark 14:51-52.

• Mark wrote his account in Rome, with his primary audience being Roman Gentiles.
• His emphasis was on Christ's actions more than his teachings. He showed Christ to not only be the son of God, but the Christ of power and action. This would have related well to the Roman Gentiles.
