Does buying kids stuff that they don't really need, often made in sweatshop type conditions, show charity or generosity?
Secular Christmas isn't the same as religious Christmas, if you want a secular "holiday," by all means, go for it. My interest is religious Christmas. Santa, as some have said, is great for imagination, and wonder, and magic, but the fictional Santa being treated as a reality isn't the only way to achieve those end. In fact, I believe that the story of the real St. Nicholas, and the legends surrounding his life, are even more powerful. And perhaps still even more powerful to realize that his spirit of charity and generosity is still active today, hundreds of years later, in his memory. No reason to make him into something he's not (a fat, jolly, old man in a red suit). Why can't he just be the Bishop of Myra?
Furthermore, Santa doesn't bring joy to anyone, but rather, others do (perhaps in his name). But that's the lesson that I'd rather have my daughter learn, not that by magic some guy flies around the world with reindeer to give out gifts, but rather that we can be like St. Nicholas by bringing joy to others. My other big issue is that the marketers/advertisers have done an excellent job in fooling us into believing that Christmas is a season of giving. It's not. It is a season of receiving. That is what the Incarnation is about.
