The evangelists have told their stories up to this point not only with a steady crescendo of drama and narrative tension... but also with a persistent build-up of scriptural quotation, allusion, reference and echo. A glance at the biblical references in the margins of Mark 11-15 will make the point. Even the burial narrative has strong biblical resonances. After this, the resurrection narratives convey the naked feeling of a solo flute piping a new melody after the orchestra has fallen silent. Granted that the evangelists felt so free, as our own scholarly traditions have insisted, to develop, expand, explain, theologize and above all biblicize their sources, why did they refuse to do so, here of all places?
