The problem is that anybody whose eyes are open and wants to love and follow our Lord knows that what is called Christmas now has been stolen by Satan. The people who don't know are the ones who revel in it.
If you want a framing story you could blend in with the facts you have, consider looking back into Bishop Nicholas's life. He was a righteous man. Not a perfect man, but he really tried. Then his bones were stolen to make a tourist attraction. What would he and St. Peter say if they were looking down on Christmas?
I'm not making this from a religous point of view I'm stating the facts I see. I'm saying it all a fake wool over your eyes a distraction a lie. (Thats how my character sees it.)
