Already prior to the release of my new forthcoming book on 'Christ's Resurrection in Early Christianity and the Making of the New Testament', a lively discussion has begun in several other bloggs, especially the one of Tim Henderson, where the headline reads 'The Irrelevancy of Jesus’ Resurrection'. Instead, however, the new book is going to advocate that Jesus' Resurrection was of eminent relevance - albeit only for specific people coming from specific religious and cultural backgrounds. Amongst the variety of forms of Judaism, only the Pharisees (and later Rabbinism) advocated a resurrection at all. How would and could Christians who came from the Sadducees, Samaritans, Essenes etc. believe in a Risen Christ who did not believe in any resurrection at all? Nevertheless, what the monograph is also going to show - what, instead of Christ's Resurrection, was core to all those Christians who had not been recruited from the Phariseic or Rabbinic background, and, how, why and when Christ's Resurrection made its way into the consciousness of early Christians.
