Originally named Saul, was a Greek-speaking Jewish man. 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. After establishing his churches during his travel, Paul remained in communication with the faithful, often writing letters to answer questions and resolve disputes. The letters that have survived have become part of the Bible. Paul's writings are important because they provide good advice for how Christians should live."
