You should celebrate Christmas if you want to, however way you see fit.
Christmas has a meaning. Part of the meaning is deeply and successfully theological, and part if the meaning is found in consumer culture.
We tend to understand consumer culture and accept it or reject it. But we don't seem to know the theological meaning of Christmas, which meaning has been elaborated over the best part of 2,000 years.
And consumer Christmas is to theological Christmas as astrology is to astronomy, or mbti is to psychometrics, or natural selection is to creationism.
Consumer culture, created by Edward L. Bernays in 1928 with his book called
Propaganda, manipulates us through our fears and our desires.
And if all we know is consumer culture, it is unlikely we will be able to transcend our fears and our desires, and we will be led around by the nose, we will be led around by our fears and our desires.
We will ridiculously insist we have the God given right to satisfy our desires, and we have the God given right not to be afraid. We will be as children dependent on a powerful parent.
