St. Paul
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.
Paul traveled the world, first to Arabia then back to Damascus. He also visited Jerusalem to see St. Peter, the first pope and pay homage to him. During these travels, he preached ceaselessly, often drawing criticism and ire from those who rebuffed his message. Jews, in particular, hated his preaching as they saw him convert people to Christianity from Judaism.
Eventually, Paul returned to Tarsus, where he was born. He preached there until he was called by Barnabus to come to Antioch. After a year spent in Antioch, a famine occurred in Jerusalem and the pair was dispatched to the city with alms.
