Ministry with Paul
Barnabas was among the first to recognize Paul after his conversion, introducing him to a community still wary of the former persecutor. From this beginning the two became inseparable companions in missionary work, traveling together through Cyprus and the Hellenized cities of Asia Minor, including the regions of Pamphylia, Pisidia, and Lycaonia.
The book of Acts records that at Lystra the people, astonished by the apostles, took Barnabas for Zeus and Paul for Hermes. Their partnership was not without tension: Paul rebuked both Peter and Barnabas at Antioch over table fellowship with Gentiles, and the two apostles later separated over whether John Mark should accompany them. The parting did not end their shared standing in the early Church, and both are remembered among its foundational missionaries.
