After the resurrection of Jesus and the event of the Pentecost the disciples began to preach about the risen Christ as Son of God and Saviour of the world. Their initial proclamation of the Christian message, which is called the primitive kerygma, consisted of brief statements, the essentials of the message, namely, the passion, death, resurrection, and glorification of Christ. Gradually, the primitive, apostolic preaching took on a narrative form and included certain brief reference to John the Baptist, to Jesus’ ministry in Galilee and in Jerusalem. Elements of this primitive apostolic kerygma can be found in the speeches of Peter in the Acts of the Apostles (Acts 2: 14-39; 3: 13-26; 4: 10-12; 5: 30-32; 10: 34-43). These important facts supplied by the primitive kerygma form the outlines of our written gospels. In other words, the gospels are extended narratives which grew out of the basic elements of the primitive kerygma.
