theological explanation #1: family squabble. Jehovah smites statue of Jesus with a bolt from the blue. Jesus refrains from miraculously restoring it. Holy Ghost stays out of it.
theological explanation #2: Jesus never really thought it was a good likeness anyway, takes out the statue himself.
non-theological explanation: high structures tend to attract lightning.
atheists' explanation: this is the result of random causation, an event without meaning in a meaningless universe.
smug atheists' explanation: this is the result of random causation that gives them a good excuse to smirk at anyone who thinks otherwise.
