The article shows how the role of Peter as the official witness to the resurrection of Jesus Christ continues to be neglected by such scholars as Martin Hengel, Christian Grappe, and Rudolf Pesch. Paul, Mark, Luke (in both his Gospel and Acts), and John offer historical and theological grounds for interpreting Peter’s primary (but not exclusive) role in emerging Christianity as that of spreading and gathering the community through the power of his Easter message. The article concludes by suggesting how the Petrine witness to Easter expresses itself in the ministry of the bishop of Rome.
