More and more, it seems to me, Charles Dickens' A Christmas Carol, with its message of redemption in this life, provides the morality of this season.
Dickens was a devout Christian himself and his faith was the grounding for his belief in social reform. Yet strip away the very pagan spirit world of the Carol and you have an extremely practical faith to live by.
Over to Marley's ghost:
"But you were always a good man of business, Jacob," faltered Scrooge, who now began to apply this to himself.
"Business!" cried the ghost, wringing its hands again. "Mankind was my business. The common welfare was my business; charity, mercy, forbearance, benevolence, were all my business. The dealings of my trade were but a drop of water in the comprehensive ocean of my business!"So the true meaning of Christmas becomes a story about Christmas. That's not just modern: it's postmodern.
