Santa wasn’t Christian to start with. Nor was caroling or eggnog, so is Christmas magic completely manufactured? Of course not. Borrowing traditions from other cultures and systems of belief has been going on from the dawn of humanity. It’s how new ideas take hold and spread. It’s not a bad thing unless credit isn’t given where credit is due.
Christianity has been the dominant world religion since the early Middle Ages, so it’s understandable that we’ve come to see its traditions as the default. Looking further back, however, fosters cross-cultural appreciation, respect and understanding. Paganism is often portrayed as “evil,” when pagan religions were once the default that Christianity is now. In reality, many pagan traditions are almost identical to the Christian ones popularly celebrated today.
That just goes to show that when we set aside our personal beliefs, we’re not that different from each other than we think.
I mean, who doesn’t like downing a glass of eggnog and opening presents?
