The Resurrection of Jesus: A Jewish Perspective

Pinchas Lapide wrote,

"When this scared, frightened band of the apostles which was just about to throw away everything in order to flee in despair to Galilee; when these peasants, shepherds, and fisherman, who betrayed and denied their master and then failed him miserably, suddenly could be changed overnight into a confident mission society, convinced of salvation and able to work with much more success after Easter than before Easter, then no vision or hallucination is sufficient to explain such a revolutionary transformation.

For a sect or school or an order, perhaps a single vision would have been sufficient – but not for a world religion which was able to conquer the Occident thanks to the Easter faith." (p 125) - Pinchas Lapide,
