One early second-century source claims that “Mark” was the apostle Peter's “interpreter” at the end of Peter's life, but no other evidence confirms that connection. Others have identified Mark as the “John Mark” who traveled with the apostle Paul (see Acts 12.12,25; 15.37–39; Col 4.10; 2 Tim 4.11; Philem 24), but none of these passages link John Mark with a written Gospel.
