Note that God is capitalized, so it’s a proper noun, a name. I’m referring to the Christian God, in this case.
Santa Claus knows when you are sleeping. He knows when you’re awake. He knows if you’ve been bad or good. Santa is omniscient. He knows all. God knows all.
Santa is completely selfless and generous. He creates infinite presents out of infinite raw material. It’s seemingly conjured out of nowhere, almost as if a… miracle… had occured. With his sled, he can defeat the laws of physics. Maybe he controls time to complete his tasks. His powers seem limitless, almost omnipotent.
Santa can reward you for good behavior, or punish you for bad. On a larger scale, this is a reflection of the “afterlife.” Instead of Christmas, it’s the day of your death. The present is heaven, with eternal rewards, and the lump of coal is hell.
The timing also helps the parallelism. Christmas takes place in the winter. Winter can be a symbol for death. Spring is the renewal, and thus, the afterlife.
So is Santa supposed to be Satan or God? Or is he just Santa? I may also attempt to compare Santa to Jesus, but not tomorrow. Tomorrow, I speak of death.
