the Paul of Tarsus metaphor is a good one.

Saul, why persecutest thou me...and a blinding light on the road to Damascus.
Of course when Paul went back to Rome and said, we've got to stop all this shit....or words to that effect. They crucified him.

its a bit like comparing a wild donkey with the seaside variety - there are similarities , but there probably are with the bloke from Manfred Mann.
