Santa Claus is not a lie. He’s a parable, a model. If you are saying Santa is a lie you are also calling Jesus a liar as he routinely taught in parables. There is a good reason for this. Fiction is a tool for disseminating the truth. A lie is something where, when you look behind it, you see nothing. With Santa when you look behind the curtain, you see something bigger more wonderful than you ever could have imagined or that could ever have been contained in a mere toy.
