Michael Pakaluk has written a new translation and commentary of Mark’s Gospel. Mark was relating very recent events, with details only an eyewitness (most likely Peter) would have mentioned. This earliest Gospel set the standard for what words and deeds of Christ would be included by the other evangelists, and reflected on by Christians until the end of the age. If these are indeed the memoirs of St. Peter “as told to” St. Mark, then, as Pakaluk says, all of the Gospels bear the mark of the Petrine ministry.
