Taken from Newdow vs. Congress (9th Circuit No. 00-16423)

"[T]he Court has unambiguously concluded that the individual freedom of conscience protected by the First Amendment embraces the right to select any religious faith or none at all. This conclusion derives support . . . from recognition of the fact that the political interest in forestalling intolerance extends beyond intolerance among Christian sects — or even intolerance among 'religions' — to encompass intolerance of the disbeliever and the uncertain."

Quoting from Wallace v. Jaffree, 472 U.S. 38 (June 4, 1985) at 52-54.
