Besides being the author of the second Gospel, he was the cousin of Barnabas (Col ) and the son of the Mary who provided a meeting place for early Christians (Acts ).
Some have even speculated that John Mark was the young man at the garden of Gethsemane during the betrayal of Jesus (Mark -52).
 What is certain is that John Mark accompanied Barnabas and Saul on the first missionary journey (Acts ; 13:5), but departed early for Jerusalem (Acts ).
Though the author does not directly identify himself, there is still strong evidence to attribute the Gospel to John Mark.
In addition to Markan composition, church fathers also state that Mark was the interpreter of Peter, which would give reason to believe that he wrote his Gospel under the guidance or assistance of the apostle.
 Like the other Gospels, the title "According to Mark" () is found in the earliest manuscripts.
With only ten verses in the New Testament making mention of John Mark, it is surprising that there is still enough information to create a sufficient biographical sketch of him.
The majority of scholarship places Mark's Gospel as the first to be composed.
 In order to properly date the Gospel it is important to consider the dating timeframe of all the Synoptics.If Luke is considered to be the latest of the Gospels, then it is important to date his Gospel first.Barnabas wanted to take John Mark, but Paul opposed the idea because Mark had departed from them on the first Journey.Consequently, Barnabas took John Mark, and Paul took Silas and the two groups went their separate ways (Acts -41).After Barnabas gave his cousin a second chance, Paul was later able to call him a coworker (Philem 24; cf. It is also evident that Mark shared a special relationship with Peter.Not only does Peter call him his son (1 Pet ), but they have both experienced failure and restoration.
