The petitioners contend, among other things, that the state laws requiring or permitting use of the Regents' prayer must be struck down as a violation of the Establishment Clause because that prayer was composed by governmental officials as a part of a governmental program to further religious beliefs. For this reason, petitioners argue, the State's use of the Regents' prayer in its public school system breaches the constitutional wall of separation between Church and State. We agree with that contention, since we think that the constitutional prohibition against laws respecting an establishment of religion must at least mean that, in this country, it is no part of the business of government to compose official prayers for any group of the American people to recite as a part of a religious program carried on by government.
