Hell, hellfire, Gehenna, other people - what's all that about?

Interest has been stirred by the move by Bishop Odd Bondevik of Norway who wants to remove the word 'hell' from the new translation of the Bible, not because he doesn't believe in it (as some don't) but because the word has been made banal by overuse (as in 'My hairdo hell, by celebrity weathergirl').  He wants to call it Gehenna. Only that's the name of a local  death metal band.  As you'd expect. So let us offer another couple of interesting and non-banal interpretations of hell.  CS Lewis in The Great Divorce  gives an idea of heaven as infinitely large, solid, real, and colourful, and hell as a dreary city of endless grey suburban streets, but which in reality is infinitesimally small - 'All Hell is smaller than one pebble of your earthly world, or one atom of this Real World'.  The notion of hell as ultimate restriction, blindness, refusal to engage with the beautiful 'reality' of goodness and God, is curiously and ironically echoed in Sartre's miserabilist play 'Huis Clos', with the famous 'L'enfer, c'est les autres'.  Confinement, boredom... nice essay here comparing it to Dante's more flamboyant torments. 'Hell is just an extension of the human condition...no need for supernatural demons or punishments'.
