The answer
A Jerusalem believer. Acts introduces John Mark through his mother's house, where the church met, and he traveled with Paul and Barnabas. No list of the twelve apostles includes a Mark.
Why it’s interesting
Letters later place him at both Paul's and Peter's side — 1 Peter calls him "my son." The earliest tradition says his Gospel preserves Peter's preaching, one step removed from an eyewitness.
