He is described in Acts as “John who was surnamed Mark” and may have come from a comfortably situated family in Jerusalem, for they had their own house and servants. His mother, Mary, was also a Christian, and the early congregation used her home as a meeting place. On the occasion when he was delivered by the angel from prison, Peter went to this house and found the brothers assembled there.​—Mark 14:51, 52; Acts 12:12, 13.

³ Mark proved himself in the ministry and became a valuable help not only to Barnabas but later also to the apostles Peter and Paul.

Then we find Mark with Peter in Babylon between the years 62 and 64 C.E. (1 Pet. 5:13)

According to the earliest tradition of Papias, Origen, and Tertullian, this source was Peter, with whom Mark was closely associated.a Did not Peter call him “my son”? (1 Pet. 5:13) Peter was an eyewitness of practically all that Mark recorded, so he could have learned from Peter many descriptive points that are lacking in the other Gospels.
