The conversion of Saint Paul took place probably in the year 36AD and the author of the Acts of the Apostles must have considered this moment very important, since he narrates it three times in his work (Acts 9; 22; 26).
The account is not a protocol by an eyewitness, but being written some 50 years later, rather an explanation motivated by the author’s theological interest in communicating his message. When Christ appears to Saul who used to persecute the Church, the light and voice from heaven give a new direction to the life of Paul, but also to the life of the whole Church: the Church opens for every nation and a true, universal mission starts.
The promise from the beginning of the Acts receive now a more profound meaning: you will receive power when the holy Spirit comes upon you, and you will be my witnesses in Jerusalem, throughout Judea and Samaria, and to the ends of the earth (Acts 1:8). This unexpected move, when a fierce persecutor becomes a disciple, will bring the gospel to the ends of the earth.
God works in an admirable way, revealing his truth step by step, as people are able to understand and follow. His salvation is spread more and more. Faith is not a privilege to be kept privately, but a treasure to be spread. Each of us, in a certain way, is Saul-Paul: we all contribute to bringing God’s light to others.
