What to know on the author of Mark (since it is anonymous)

The author of Mark is anonymous, Eduard Schweizer says: “He is Hardly to be identified with Mark mentioned in Acts, Philemon, Colossians, Timothy, since he does not seem to know the geography of Palestine. Furthermore, he writes in a very polemical way against Jewish customs”

1. Also Werner Kümmel says: “The author obviously has no personal knowledge of Palestinian geography, as the numerous geographical errors show. He writes for gentile Christians, with sharp polemic against the unbelieving Jews”

1. gMark may have been written by A Mark/Marcus although not THE John Mark. Joel Marcus in his 1992 article “The Jewish War and the Sitz Im Leben of Mark” writes:
2. The reliability of the tradition transmitted by Papias, however, is open to question. Papias’ main assertion, the linkage with Peter’s eyewitness testimony, is belied by a form-critical analysis of Mark; the Gospel seems to be several steps removed from eyewitness testimony, consisting rather of a collection of traditions that have gone through considerable development in the course of their transmission. There is, moreover nothing particularly Petrine about these traditions.8 Papias’s account is probably a reflection not of historical information but of two other factors: (1) A knowledge of the association of the names of Mark and Peter in 1 Pet 5:13 and (2) a desire on the part of second-century “orthodox” church leaders to link the four Gospels with known disciples as a weapon against the Gnostics. If one asked why Papias chose to link the Gospel directly with Mark rather than with Peter, the answer would be that “Mark” was associated with the Gospel from a very early period and may indeed be the name of its author. This Mark who wrote the Gospel however, was probably not, as Papias seems to have assumed him to be, John Mark, the native of Jerusalem who became the companion of Paul. “Mark” was one of the commonest names in the Roman Empire, and the form-critical argument made above against the linkage of the Gospel with the eyewitness account of Peter would also apply to a linkage with the other apostles who would have been personally known by John Mark.
3. Joel Marcus goes on to argue that gMark was written by a Jewish Christian refugee from Palestine who fled to Syria.
