It is traditionally held that Mark wrote his gospel based on information he learned from St. Peter, after having been his travelling companion.
Where does this claim come from?
And would it surprise you to know that we have a first century source that claims precisely this?
Here’s the story . . .
What We Know About Mark
We know that Mark was a travelling companion of Peter, because Peter mentions the fact in his First Epistle (1 Peter 5:13).
We also know that Mark was a travelling companion of other apostles, including Paul and Barnabas, which Luke discussed in Acts.
Mark may have even been an eyewitness of part of Jesus’ earthly ministry. It is often thought that he refers to himself, anonymously, in his own gospel, as the man carrying a jug of water on his head or as the man who slips out of his clothes and runs away naked on the night Jesus is arrested.
Also, as Luke mentions in Acts, Mark’s mother was prominent in the early Christian community, which at times met at their house in Jerusalem.
So why would we suppose that Mark got the information from St. Peter in particular?
