Growing up in the Reform community in the US in the 50s and 60s, I remember the constant discussions of the Chanukah-Christmas dilemma. Was it possible to disengage Chanukah from the seasonal linkage to Christmas, and keep it somehow true to its roots? Or was it doomed to be "the Jewish answer to Christmas," which increasingly meant an orgy of shopping and materialism?
I’m pretty sure my family coined the term Christmukkah. We were interfaith hipsters, once we realized that the alternative, Festivus, wasn’t really for the restofus.
The Hebrew word hanukkah means "dedication," and refers to the rededication of the second temple to the service of God during the successful revolt of the Maccabees against the Seleucid rulers of Syria in the second century BCE.
