Some important foundational teaching on ONE of the aspects of drama. But it also works in reverse.... it helps to show you how powerful evangelistic drama is....the Oberammergau festival. Last year in Havant when a passion play was put on in summer in Havant Park. Truly powerful. The person who apprenticed me in pianos was converted through the Zeffirelli films Jesus of Nazareth. And Paul used the powerful phrase in Galatians.... Jesus Christ who was publicly portrayed as Crucified
