"The First Amendment...does not say that in every respect there
shall be a separation of Church and State. ... Otherwise the state and
religion would be aliens to each other -- hostile, suspicious, and even
unfriendly. ... The state may not establish a 'religion of secularism'
in the sense of affirmatively opposing or showing hostility to religion,
thus preferring those who believe in no religion over those who do
believe." --- Justice William O. Douglas.
