Explanation

Paul undertook three missionary journeys spreading Christianity across the Roman Empire (Acts 13-21). First journey: Cyprus and southern Turkey. Second: Greece (Philippi, Thessalonica, Corinth). Third: extended stay in Ephesus.

Strategy: start in synagogues reaching Jews, then turn to Gentiles. Establish churches, appoint elders, write letters of instruction. Face persecution but persist. Use Roman citizenship for protection.

Pauls journeys transformed Christianity from a Jewish sect to a worldwide faith. His letters (epistles) form much of the New Testament. He died in Rome, probably executed under Nero.
