The writer did not identify himself as the writer anywhere in this Gospel. There are many statements of the early church fathers, however, that identify John Mark as the writer.
The earliest reference of this type is in Eusebius' Ecclesiastical History(c. 326 A.D.).1Eusebius quoted Papius' Exegesis of the Lord's Oracles(c. 140 A.D.), a work now lost. Papius quoted "the Elder,"probably the Apostle John, who said the following things about this Gospel. Mark wrote it though he was not a disciple of Jesus during Jesus' ministry nor an eyewitness of Jesus' ministry. He accompanied the Apostle Peter and listened to his preaching. He based his Gospel on the eyewitness account and spoken ministry of Peter. Mark did not write his Gospel in strict chronological sequence, but he recorded accurately what Peter remembered of Jesus' words and deeds. He considered himself an interpreter of Peter's content. By this John probably meant that Mark recorded the teaching of Peter for the church though not necessarily verbatim as Peter expressed himself.2Finally the Apostle John said that Mark's account is wholly reliable.
Another important source of the tradition that Mark wrote this Gospel is the Anti-Marcionite Prologue to Mark (160-180 A.D.). It also stated that Mark received his information from Peter. Moreover it recorded that Mark wrote after Peter died and that he wrote this Gospel in Italy.
Irenaeus (c. 180-185 A.D.), another early church father, added that Mark wrote after Peter and Paul had died.3
Other early tradition documenting these facts comes from Justin Martyr (c. 150-160 A.D.), Clement of Alexandria (c. 195 A.D.), Tertullian (c. 200 A.D.), the Muratorian Canon (c. 200 A.D.), and Origen (c. 230 A.D.). Significantly this testimony dates from the end of the second century. Furthermore it comes from three different centers of early Christianity: Asia Minor (modern Turkey), Rome (in Italy), and Alexandria (in Egypt). Thus there is strong evidence that Mark wrote this Gospel.
The Mark in view is the John Mark mentioned frequently in the New Testament (Acts 12:12, 25; 13:5, 13; 15:36-39; Col. 4:10; Phile. 24; 2 Tim. 4:11; 1 Pet. 5:13). He was evidently a relative of Barnabas who accompanied Barnabas and Paul on their first missionary journey but left these apostles when they reached Perga. He became useful to Paul during Paul's second Roman imprisonment. He was also with Peter when Peter was in Rome, and Peter described him as his "son,"probably his protégé.
It seems unlikely that the early church would have accepted this Gospel as authoritative, since its writer was a secondary figure, without having convincing proof that Mark wrote it. Perhaps Luke showed special interest in John Mark in Acts because he was the writer of this Gospel more than because he caused a breach between Paul and Barnabas.4
