I have always been happy to celebrate Christmas or visit a church. In the first case it is no more than a seasonal holiday about winter, in the second it is architecture of a special kind.
'Put Christ back in Christmas' may lead you to do the numbers. For every creche there are one thousand North Sea Santas, ten thousand Scandanavian in-door pine trees and a million North European winter lights that would have been irrelevant in Israel 2,000 years ago.
Enjoy the music too. For every 'Silent Night' there are four times as many songs written by Jews in the early 20th Century and by secular celebrities. As for Christmas stories, Ruldoph the Red Nosed Raindeer and the song sung by Frank Sinatra were written by Jews, schoolmates of my mother.
