Paul’s epistles to the Thessalonians show a vivid snapshot of the church in mission. Paul was sent from the church in Antioch as a mission to the Gentiles to Cyprus.
The Antiochan church was being torn apart by the question of whether Gentiles must be circumcised. The Council of Jerusalem would decide that Gentiles must abstain from idolatry, abstain from sexual immorality and abstain from meat with blood. Paul returns from Jerusalem with this information to Antioch. There he splits with Barnabus and continues his missionary journeys returning to Greece and Crete.
