Oscar Cullmanns 1962 revision of Peter in turn carefully treats the Historical Question and the Exegetical and Theological Question of the apostle Peter. While Cullmann cannot decisively confirm some of the details of Peters lifehis residence in Rome and the location of his grave, in particularother details are described as more probable, such as Peters travel to Rome and his martyrdom under Nero. Cullmann faithfully seeks Catholic-Protestant dialogue while maintaining that Jesus wordsupon this rock I will build my churchrefer to the apostle alone and provide no historical basis for succession. The timeless quality of Cullmanns methods and his overwhelming concern for Christian unity are sure to inspire new generations of biblical scholars and contemporary theologians.
