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 and have influenced the growth and development of the Church since the first century.
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 while on the road to Damascus. He was duly baptized and took the name Paul.
