Attalia appears in Acts 14:25 during the concluding stage of Paul and Barnabas' first missionary journey. After revisiting the newly established congregations in Asia Minor, the missionaries passed through Pisidia and Pamphylia, preached again in Perga, and then traveled to Attalia.
Acts 14:26 states that from this region they sailed back to Antioch, where they reported what God had done through them and how a door of faith had been opened to the Gentiles.
Attalia thus served as the maritime departure point marking the completion of an important early phase of Gentile mission.
