THIS, Camping has now explained what really happened on May 21. But just in case you don't want to give Camping any more attention than he deserves by reading the report, allow me to translate his excuse:
When your doomsday end-of-the-world prediction doesn't come to pass; give it a "spiritual" meaning instead.
Where have we heard THAT EXCUSE before?
