From Richard Hammond's book "On the edge:My story"

Hammond is the BBC Top Gear presenter who crashed a jet powered car at
300mph and suffered a brain injury.

"He explained that sudden obsessions or compulsions can leap up,
seemingly from nowhere. They might be to give away all your money, quit
a stressful job or to become fervently religious"

(Hammond in conversation with his consultant neurologist, Page 233)

So when the Atlanta Police department beat Chung like a rented mule,
added to his schizophrenic personality, that's where all this phony
religious stuff comes from. He got his head beaten like a ripe  
watermelon and came out of it thinking he was St Chung the Craptist.

His "convicted" schitck and refusal to go inside a church is more to do
with being whipped like a stray dog than any religious experience.

Basically, he is brain damaged.
