Mark's Gospel, which is thought by biblical scholars to be the earliest, has the name of a young disciple of the apostle Paul who is mentioned several times in the "Acts of the Apostles" and Paul's Letters. The Gospel was probably written in Rome and is thought by scholars to be from the memories of Jesus' follower or "disciple", Peter. It does not tell about Jesus' birth; it starts when he was 30 years old, at the time when the disciples got to know him. It shows Jesus as a man of action: going around the country, teaching and healing people.
