Saint Paul is one of the most important and influential of all the saints. Many of his writings are contained in the Canon of the Bible.St.Paul was originally known as Saul, and he was a Roman citizen and a Pharisee.He even presided over the persecutions of the early Christians and was present at the martyrdom of St. Stephen. However, Saul experienced a powerful vision that caused him to convert to Christianity. Paul traveled throughout much of Europe, particularly in Macedonia, Greece, and Italy. After establishing his churches, Paul remained in communication,often writing letters to answer questions and resolve disputes. The letters that have survived have become part of the Bible.
