Harry Blackmun,
County of Allegheny v. American Civil Liberties Union…
“ The mere fact that Pittsburgh displays symbols of both Christmas and Chanukah does not end the constitutional inquiry. If the city celebrates both Christmas and Chanukah as religious holidays, then it violates the Establishment Clause. The simultaneous endorsement of Judaism and Christianity is no less constitutionally infirm than the endorsement of Christianity alone. ”
