(a) Mass persecution started in Jerusalem after Stephen's death. The Church became panicky and fled from Jerusalem to other places (Judea, Samaria, etc). Wherever they went, they preached and converted many to the faith. Philip, one of the seven deacons fled to Samaria and proclaimed the Gospel message in Samaria. When the people of Samaria heard and saw the miracles he performed, many were converted. He cast out demons from those possessed and healed those who were paralysed. Philip encountered a magician called Simon who had deceived many people who thought he had the power of God. Simon too was converted and was baptized. The good work of Philip in Samaria reached the apostles in Jerusalem. Peter and John were impressed and they prayed and laid their hands on the new converts to receive the Holy Spirit.
Simon attempted to bribe Peter to give him the power to impart the Holy Spirit to others, but, Peter rebuked him saying, "your silver perish with you ...". Simon became frightened after the words of Peter and asked Peter to pray for him.

(b) The activity of the Holy Spirit was manifested in Samaria in the following ways:.
(i) Healing of the sick;
(ii) Casting out of demons;
(iii) Working of miracles;
(iv) Exposure of Simon's selfishness/condemnation of Simon;
(v) Conversion of unbelievers;
(vi) Pressure of the Holy Spirit to empower the disciples/the church.
