Christmas is a dual holiday. On the same day the birth of Jesus and the ideals of Christian charity are celebrated, though there is a simultaneous holiday which been foisted on us by occult forces who exercise increasing influence in our world. The other Christmas involves silly myths which include a fat man in a red suit with magical powers who lives in the North Pole.
Santa is an anagram for Satan. Santa has no Christian associations at all, but is rather the survival of the ancient worship of the god of the underworld, in the form of Saturn.
