Mark

Mark (Latin Marcus), also called John Mark — John his Hebrew name, Mark his Roman surname — was an early Jerusalem disciple, companion of Paul, Barnabas, and Peter, and the traditional author of the second Gospel. His career is a small but vivid story of failure, restoration, and usefulness that the New Testament does not hide.

Mark was the son of a certain Mary of Jerusalem, a woman of means in whose house the church gathered to pray; it is to that house that Peter goes when an angel frees him from Herod's prison (Acts 12:12). He was the cousin of Barnabas (Colossians 4:10), and when Barnabas and Saul returned from Jerusalem to Antioch they brought Mark with them (Acts 12:25). He set out as their helper on the first missionary journey but turned back at Perga in Pamphylia and went home to Jerusalem (Acts 13:13). Paul judged this desertion serious enough that, when Barnabas wished to take Mark again, the disagreement grew so sharp that Paul and Barnabas parted ways — Barnabas taking Mark to Cyprus, Paul taking Silas (Acts 15:37–39).

The breach, however, did not last. By the time of Paul's imprisonment Mark is again at his side and commended to the churches (Colossians 4:10; Philemon 1:24), and in Paul's final letter the apostle asks for him by name: "Get Mark and bring him with you, for he is very useful to me for ministry" (2 Timothy 4:11) — a quiet vindication of the man who once turned back. Peter, writing from "Babylon," calls him "my son Mark" (1 Peter 5:13), marking the close bond from which the Gospel tradition flows.

Ancient testimony, traced through Papias of Hierapolis (preserved by Eusebius), identifies Mark as Peter's interpreter, who set down accurately, though not in order, the things Peter preached about the Lord. The Gospel that bears his name fits this account: it is the shortest and most fast-moving of the four, fond of the word "immediately," rich in concrete eyewitness detail, and centered on Jesus' deeds, His authority, and His path to the cross. It opens by announcing "the beginning of the gospel of Jesus Christ, the Son of God" (Mark 1:1) and turns on the confession of Jesus as Christ and the prophecy of His suffering (Mark 8:29). Mark's life thus mirrors his message: that grace restores the failing servant and makes him useful in the work of the gospel. Tradition further links him with the founding of the church in Alexandria.
