Grief Best Explains The Resurrection Hypothesis

Gerd L├╝demann is a scholar many of us are familiar with, having written important books like: Resurrection of Jesus; The Resurrection Of Christ; and What Really Happened to Jesus? He argues in a recent piece:
By a bold if unconscious leap, Peter entered the world of his wishes. As a result he “saw” Jesus, concluded that his Lord had risen from the dead, and by witnessing to his vision made it possible for the other disciples to “see” Jesus in the same way. It would therefore seem all but certain that the Christian church is to some extent the historical result of the disciples’ grief. Link
