Paul of Tarsus was perhaps the most important figure in the early history of Christianity. He was the person who did more than anyone to spread the new faith.
Paul was born as a Jewish citizen of Rome whose name was Saul. He was involved in the persecution of Christians. He then experienced a conversion incident sometime in the 30s AD. After that, he became a promoter of Christianity. He is particularly important because he wanted the faith to expand beyond its Jewish roots. He was instrumental in spreading the faith to the Gentiles. He was responsible for setting up Christian communities in non-Jewish areas such as Asia Minor. For this reason, he is sometimes called the second founder of Christianity.
