Mark the cousin of Barnabas is a figure mentioned in the New Testament, usually identified with John Mark (and thus with Mark the Evangelist)."Apostle and Evangelist Mark", Orthodox Church in America

Biblical record Mark accompanied Barnabas and Paul on their missionary travels."The Life and Gospel of Saint Mark the Evangelist", Basilica of the Immaculate Concption Mark started with them on their first trip,Acts 13:5 but left them partway through.Acts 13:13 Later, when planning their second trip, Barnabas and Paul could not agree about whether Mark should accompany them again, so Barnabas and Mark separated from Paul.Acts 16:36-40

Later, Paul appears to have been reconciled to Mark, for he mentions him positively in Colossians 4:10: "Aristarchus, my fellow prisoner, sends you his greetings; and also Barnabas's cousin Mark (about whom you received instructions; if he comes to you, welcome him)."New American Standard Bible 1995 Update (NAU), Col 4:10 A person named Mark is also mentioned in Paul's letter to Philemon, "Epaphras, my fellow prisoner in Christ Jesus, greets you, as do Mark, Aristarchus, Demas, Luke, my fellow workers. (Philemon 1:23-24 NAU) This indicates that Mark the Cousin of Barnabas was with Paul during his First Imprisonment in Rome, during which he wrote the four Prison Epistles (Ephesians, Colossians, Philemon, and Philippians).

Identification According to Hippolytus of Rome, in his work On the Seventy Apostles, Mark the cousin of Barnabas (Colossians 4:10; ) is distinct from John Mark (Acts 12:12, 25; ) and Mark the Evangelist (perhaps the Mark in 2 Timothy 4:11?). They all belonged to the Seventy Apostles of Christ (ranked #56, #65, and #14, respectively), who were sent out by Jesus to saturate Judea with the gospel not long before his crucifixion (ff.).Ante-Nicean Fathers, ed. Alexander Roberts, James Donaldson and A. Cleaveland Coxe, vol. 5 (Peabody MA: Hendrickson Publishers, 1999), 255-6 Hippolytus says that Mark the cousin of Barnabas was a leader of the apostolic church and the bishop of Apollonia. (There are three possible sites for this place: one in Albania, one in Thrace, and one in Cyrenaica.)

Biblical scholars Samuel Rolles Driver and Charles Augustus Briggs identified Mark, the cousin of Barnabas, with John Mark of Jerusalem,Driver, Samuel Rolles.
