St. Matthew the Apostle was a Roman tax collector, a job considered to be working with the enemy by people who had to pay the taxes. When people were surprised to find Jesus with the “traitor,” Jesus said he had come to call the sinners. St. Matthew wrote his Gospel to convince the Jews that Jesus was the Messiah. The saint preached to the Jewish people for 15 years. St. Matthew the Apostle is patron saint of tax collectors, bankers and money managers in general.
