The Biblical case against Santa: Santa Clause: The Great Imposter
The short version: Santa is Satanic.
Where does Santa Claus fit in the life of a young child? What about the teaching of Santa Claus in the psyche of a child? Is there more to jolly old St. Nick than meets the eye? Is Santa a clever, seemingly harmless, subtle (see Genesis 3:1) attempt to question the truthfulness of God? Is Santa the handiwork of Satan?
...
The Devil is a master of disguise. He can make it appear good, pleasant, and seemingly so innocent – and yet it is deadly! The Bible says in 2 Corinthians 11:14, "And no marvel; for Satan himself is transformed into an angel of light" He does not appear with horns and a pitch fork breathing fire. He might just appear as a pleasant, friendly, fellow, with "a broad face and a round little belly, That shook when he laughed, like a bowl full of jelly. . ."
Could Santa Claus be a subtle, clever attack on our children to confuse, doubt and rob their God-ordained "child like" faith? Satan knows, if he can somehow get that child through those fruitful early years without trusting the Lord Jesus Christ – his goal of eternal damnation in hell increases substantially.
There's a shitload more, for your amusement.
In 1994, the satire magazine The Onion carried a parody of Santa Claus titled "Ho! Ho! Ho! I Am God". Even though, it was written as a blasphemous parody much truth rings from the article. The article says:
"I love visiting each and every one of your homes, stuffing your stockings with toys, and enjoying the milk and cookies you leave for me. But mostly I love Christmas because it's the celebration of the birth of my son, Jesus the Christ. You see, I'm God. . . Don't I look familiar? I'm old, I have a white beard, I love everyone. I'm the same God as the one you and your mommy and daddy worship on Sundays. . .
Okay, I admit it. I'm not God. But I'm better than God. I'm jollier, and I give you real toys, not boring old psalms and empty promises you can only collect on when you die. Worship me, not Him! Worship Santa! I am God!"
(Santa Claus, "Ho! Ho! Ho! I Am God!" The Onion, 29 Nov. - 5 Dec., 1994, p. 7)
And that is EXACTLY the message being preached to these little children! And they believe it!
