Who wrote the book of Mark in the Bible

Who wrote the Gospel of Mark? The traditional answer is John Mark. However, early Christian history also connects this Gospel closely with the Apostle Peter. While Mark wrote the book, many Christians believe he recorded Peter’s eyewitness testimony about the life and ministry of Jesus Christ.

John Mark: The Traditional Author

The early Church consistently identified John Mark as the author of the Gospel of Mark.

Mark appears several times in the New Testament as a missionary companion of the Apostle Paul. Later, he became a close associate of the Apostle Peter.

Although Mark was not one of the Twelve Apostles, early Christians believed he faithfully recorded the teachings he received from Peter.

What Early Church Leaders Said

One of the earliest witnesses to the Gospel’s authorship was Irenaeus, a second-century bishop.

“Mark, the disciple and interpreter of Peter, also handed down to us in writing what had been preached by Peter.”

This statement explains why many Christians believe Mark served as Peter’s interpreter or recorder. Rather than writing from his own eyewitness experience, Mark preserved Peter’s preaching in written form.

Peter’s Relationship with Mark

The New Testament also highlights the close relationship between Peter and Mark.

In 1 Peter 5:13, Peter refers to “Mark, my son.” Most scholars understand this as a spiritual relationship rather than a biological one.

Because Peter personally witnessed Jesus’ ministry, death, and resurrection, his testimony carried tremendous authority in the early Church.

Therefore, many believers view the Gospel of Mark as Peter’s eyewitness account written by John Mark.

Who Wrote the Gospel of Mark According to Tradition?

The traditional Christian view can be summarized as follows:

  • Author: John Mark
  • Main source: The Apostle Peter
  • Purpose: To record Peter’s eyewitness testimony about Jesus Christ

Although modern scholars continue to discuss the Gospel’s authorship, the earliest Christian tradition consistently attributes the writing to John Mark and connects its content to Peter’s preaching.

Conclusion

Who wrote the Gospel of Mark? According to early Christian tradition, John Mark wrote the Gospel while recording the teachings of the Apostle Peter. As a result, the Gospel combines Mark’s writing with Peter’s firsthand testimony, giving readers a vivid and fast-paced account of the life, death, and resurrection of Jesus Christ.
