Don't be frightened by Jesus - nor his shroud (a medieval fake). My next-door neighbour goes out preaching in the evenings and your mate hasn't gone that far (yet). I ask him secular questions about the bible stories and he just tries to get away as fast as possible. I'm still waiting for him to find out the name of the guy that allegedly helped Jesus carry his (alleged) cross. Was it Simon the Cyrene? Or is Jesus just a dressed up hallucinogenic mushroom myth?
