Paul's visits to the church in Jerusalem. Sources outside the New Testament that mention Paul include: Clement of Rome's epistle to the Corinthians (late 1st/early 2nd century); Ignatius of Antioch's epistles to the Romans and to the Ephesians (early 2nd century); Polycarp's epistle to the Philippians (early 2nd century); Eusebius's (early 4th century); The apocryphal Acts narrating the life of Paul (Acts of Paul, Acts of Paul and Thecla, Acts of Peter and Paul), the apocryphal epistles attributed to him (the Latin Epistle to the Laodiceans, the Third Epistle to the Corinthians, and the Correspondence of Paul and Seneca) and some apocalyptic texts attributed to him (Apocalypse of Paul and Coptic Apocalypse of Paul). These writings are all late (they are usually dated from the 2nd to the 4th century).

One of the larger centers of trade on the Mediterranean coast and renowned for its university, Tarsus had been among the most influential cities in Asia Minor since the time of Alexander the Great, who died in 323 BC. Paul referred to himself as being "of the stock of Israel, of the tribe of Benjamin, a Hebrew of the Hebrews; as touching the law, a Pharisee". The Bible reveals very little about Paul's family. Acts quotes Paul referring to his family by saying he was "a Pharisee, born of Pharisees". Paul's nephew, his sister's son, is mentioned in Acts 23:16. In Romans 16:7, he states that his relatives, Andronicus and Junia, were Christians before he was and were prominent among the Apostles. The family had a history of religious piety. Apparently, the family lineage had been very attached to Pharisaic traditions and observances for generations. Acts says that he was an artisan involved in the leather crafting or tent-making profession. This was to become an initial connection with Priscilla and Aquila, with whom he would partner in tentmaking and later become
