I bought last year's Christmas cards from UNICEF -- a worthy charity gets some cash; my friends and family get some attractive artwork and cozy holiday wishes to decorate their mantelpiece/refrigerator/trash can; everybody wins. I probably won't be sending cards this Christmas (maybe we should add "P.S. Happy Holidays!" to our wedding invitations?), but when the UNICEF Cards & Gifts catalog arrived this week, I flipped through it anyway. My favorite Xmas card design was "City of Bethlehem" -- until I read the description more carefully. What's wrong with this picture? "Embossed with bronze accents, the City of Bethlehem glows in the evening sun, while a shimmering star guides Joseph and Mary." That star is pretty and all, but I'm pretty sure that's not how the story goes.
Seriously though: UNICEF does good work; their Christmas cards are nice; you should consider buying some... but if you go the religious route, maybe look for a design with a slightly better grasp on the nativity story details.
What global not-for-profit will I find petty fault with tomorrow? Come back and see!
