the naughty list is most clearly referenced in Exodus 20:2-17 and Deuteronomy 5:6-21, although there are other places where good advice is offered about ow not to end up on that list. the 'good list' (assuming you see Santa as the spirit of Christmas, a somewhat less denominational, more broadly appealing manifestation of the Holy Spirit) is most clearly referenced in the New Testament's John 3:16. If you don't have your Bible handy, George Carlin did a piece called the Two-minute Warning' that is still relevant today. Carlin's language is not entirely child-appropriate, so depending on one's age, the Santa Claus legend might be a more suitable introduction to the idea of 'good' behavior.
