In this post I’m moving first to Mark’s Gospel before looking at any other major books or passages of the NT because the tradition of the early church, following the testimony of Papias (preserved for us by Eusebius) is that Mark’s Gospel is a summary of Peter’s preaching in Rome. What is interesting about this view is that the general contours of Mark’s Gospel follow the general outline of Peter’s preaching recorded in the Book of Acts. If you take a look, for example, at Acts 10:36-43, we see that Peter begins his preaching about Jesus with Jesus’ baptism by John the Baptist. Of all four Gospels, only Mark begins in this way. Moreover, in 1 Peter 5:13, we find Peter referencing a “Mark” as his travelling companion, both of whom send their greetings from Rome.
The Petrine nature of Mark’s Gospel, although dismissed by most scholars, is noted by Dr. Richard Bauckham. Dr. Bauckham points out that,
Since Matthew’s Gospel has a special interest in Peter…it is very noteworthy that Mark mentions Peter by name considerably more frequently than Matthew does. Furthermore—a point of considerable importance for our argument that Mark’s Gospel claims Peter as its principal eyewitness source—Peter is actually present through a large portion of the narrative….1
