Well, not log to go before its on TV/Internet. To me it all makes sense anyway...Party leader speaks a bit too freely, causes riots, gets caught by the authorities and is punished. Fair enough. The Party thinks that without their charismatic leader they'll perish so they keep his name alive, they create a few rumours...stories....soon the people are thinking he was more than mortal etc etc. As far as the family tomb in Jerusalem is concerned, he probably made quite a bit of cash out of the odd sermon so he was able to afford a nice tomb for his family...
Long Live the Republic.
