Agreed. By the way, a Menorah should also be viewed as a Christian symbol, since we Christians believe we are the offsrping of the Jewish religion that was saved in the miracle of the Menorah. I am sure Jesus celebrated Hanakka.

Not something I'm an authority on, but I think the Feast of Dedication referred to in John was Hanukah.
