Eusebius preserved valuable traditions of Papias going back to St. John concerning the origins of the gospels of Mark and of Matthew. Before writing the Greek gospels we have, between AD 42 and 46, Mark made an unordered notebook of Peter’s memoirs about Jesus, and Matthew arranged Jesus’s words and deeds into an integrated narrative in Hebrew. These drafts were for private circulation among close acquaintances and were never published. Matthew’s could have served as a memory prop for the apostles’ oral deliveries in missionary situations. It probably informed the triple tradition behind the synoptic gospels.
