Acts 12:12

Peter went directly to a home where he may have known that Christians would be praying for him. This was the house of Mary the mother of John (Jewish name) Mark (Greek name). Barnabas sold his land and gave it to the church (Acts 4:37), but Mary kept her house. This shows that communal living was not required among the early Christians. John Mark was the man who accompanied Paul and Barnabas on their first missionary journey (Acts 13:5). He was Barnabas’ cousin (Colossians 4:10) who travelled with Barnabas to Cyprus when Paul chose Silas as his companion for his second missionary journey (Acts 15:37-39). Mark later accompanied Paul again (Colossians 4:10; Philemon 1:24), as well as Peter (1 Peter 5:13). According to early church tradition he wrote the Gospel that bears his name, served as Peter’s interpreter in Rome, and founded the church in Alexandria, Egypt.
