Born in Tarsus in Tarsus in Cilicia. Paul was brought up in Jerusalem and educated under Gamaliel. As a strict Pharisee, he persecuted the early Christians, having them arrested and imprisoned. On the road to Damascus, he encountered the risen Christ and experienced a conversion, a metanoia or change of mind/outlook concerning Jesus: Jesus really is Lord, glorified by God. From a bold persecutor, Paul became a tireless preacher of the gospel.
God our Father, you taught the gospel to all the world through the preaching of Paul your apostle. May we who celebrate his conversion to the faith follow him in bearing witness to your truth. Through Christ our Lord. Amen.
