The Bethsaida Miracle

Quoting D. Keith Mano:

Virgil, age fifty and blind since childhood, has had "successful" eye surgery.  Five weeks later "he often felt more disabled than he had felt when he was blind. ... Steps ... posed a special hazard, because all he could see was a confusion, a flat surface of parallel and crisscrossing lines; he could not see them (although he knew them) as solid objects going up or coming down in three-dimensional space."

The article goes on to discuss the blind man in Mark 8:22.  Jesus healed the man’s eyes, and the man then said he saw people who appeared to be walking trees.  So Jesus laid his hands on the man a second time, and his sight was restored fully.

Quoting D. Keith Mano:

As far as I can judge, this is irrefutable evidence that a miracle did occur at Bethsaida.  Back in 30 A.D. the blind did not often receive sight: there were few, if any, eye surgeons and seldom a decent miracle-worker.  No shill in the crowd could have faked it all by pretending to be blind -- because only someone recently given his sight would see "men as trees, walking," would see the Cubist jumble that Virgil told Oliver Sacks about.  A faker, not knowing about post-blind syndrome, would have reported that Jesus had given him perfect vision.
