Biblical Christianity 101, a study of the book of Romans

How do we know that Mark wrote the gospel of Mark? How do we know that Mark recorded the observations of an eyewitness?

The short answer is because Papias (< 70 – c. 155) said so. Papias was a bishop and an avid documenter of oral history from the early church. His book Interpretations was written after 120 CE.
Jesus died in 30, Mark was written in 70, and Papias documents Mark as the author in 120 (dates are estimates). That’s at least 50 years bridged only by “because Papias said so.”

But how do we know what Papias said? We don’t have the original of Papias, nor do we have a copy. Instead, we have Church History by Eusebius, which quotes Papias and was written in 320.

And how do we know what Eusebius said? The oldest copies of his book are from the tenth century, though there is a Syriac translation from 462.

Count the successive people in the claim “Mark wrote Mark, which documents an eyewitness account”: (1) Peter was an eyewitness and (2) Mark was his journalist, and (3) someone told this to (4) Papias, who wrote his book, which was preserved by (5) copyist(s), and (6) Eusebius transcribed parts of that, and (7) more copyist(s) translated Eusebius to give us our oldest manuscript copy. And the oldest piece of evidence that we can put our hands on was written four centuries after Mark was written.
