Resurrection = The Dawn of the New Creation

Jeremias:

There is nothing comparable to the resurrection of Jesus anywhere in Jewish literature. Certainly there are mentions of raisings from the dead, but these are always resuscitations, a return to earthly life. Nowhere in Jewish literature do we have a resurrection to doxa as an event of history. Rather, resurrection to doxa always and without exception means the dawn of God's new creation. Therefore the disciples must have experienced the appearances of the Risen Lord as an eschatological event, as a dawning of the turning point of the worlds.
