The whole movie is about ArchBishop
              Oscar Romero who is martyr. You can add that it is about
              Transformation, because Romero is transformed by his encounter
              with the poor.  The most powerful scene in the movie is one
              about the spiritual battle between good and evil. 
              "Romero goes to the village that is under martial law. 
              He enters the church that has been transformed into the barracks
              to get the eucharist where he is beaten by the soldiers.  He
              returns to confront the soldiers and the power of good seen in the
              poor of El Salvador overcomes the soldiers, the forces of
              evil." (submitted by Guido Climer)
