Silas (or Silvanus) was a prominent member of the Jerusalem church who accompanied Paul on his second missionary journey and co-wrote some of his epistles.
Silas, also known by the Latinized form Silvanus, was a leader in the Jerusalem church (Acts 15:22) and Paul's missionary companion on his second journey through Syria, Cilicia, Macedonia, and Greece after his split with Barnabas. He and Paul were miraculously freed from a Philippian jail by an earthquake that led to the jailer's conversion (Acts 16:25–34), a famous scene in Acts. He worked alongside Paul in Thessalonica, Berea, and Corinth, and both 1 and 2 Thessalonians are addressed from Paul, Silas, and Timothy (1 Thessalonians 1:1). Peter's first letter also mentions Silvanus as its amanuensis (1 Peter 5:12), suggesting he maintained a connection to the Roman church. He is an example of the leadership overlap between the Jerusalem and Pauline wings of the early church.
