How do you politely tell a friend on Facebook to shut up about religion?

As we approach the holiday season we see more and more biblical quotations and religious references on FB. For those of us who are not religious it often comes off as pedantic, pointless, annoying and superstitious. I don’t want to alienate my religious friends but I’m also getting sick and tired of having their religion shoved down my throat every time I leave a status update.

Any advice? I’d be interested in getting answers from theists as well as atheists.
