Tom C. Clark,
Abington School District v. Schempp…
(1963)
“ We have come to recognize through bitter experience that it is not within the power of government to invade that citadel, whether its purpose or effect be to aid or oppose, to advance or retard. In the relationship between man and religion, the State is firmly committed to a position of neutrality. Though the application of that rule requires interpretation of a delicate sort, the rule itself is clearly and concisely stated in the words of the First Amendment. ”
