To hold that a state cannot, consistently with the First and Fourteenth Amendments, utilize its public school system to aid any or all religious faiths or sects in the dissemination of their doctrines and ideals does not, as counsel urge, manifest a governmental hostility to religion or religious teachings. A manifestation of such hostility would be at war with our national tradition as embodied in the First Amendment’s guaranty of the free exercise of religion. For the First Amendment rests upon the premise that both religion and government can best work to achieve their lofty aims if each is left free from the other within its respective sphere.
