religion includes many things from prayer in widely varying government settings over financial aid for religious individuals and institutions to comment on religious questions. The Supreme Court stated in this context: "In these varied settings, issues of about interpreting inexact Establishment Clause language, like difficult interpretative issues generally, arise from the tension of competing values, each constitutionally respectable, but none open to realization to the logical limit." The National Constitution Center observes that, absent some common interpretations by jurists, the precise meaning of the Establishment Clause is unclear and that decisions by the United Supreme Court relating to the Establishment Clause often are by 5–4 votes. The Establishment Clause, however, reflects a widely held consensus that there should be no nationally established church after the American Revolutionary War. Against this background the National Constitution Center states: Virtually all jurists agree that it would violate the Establishment Clause for the government to compel attendance or financial support of a religious institution as such, for the government to interfere with a religious organization's selection of clergy or religious doctrine; for religious organizations or figures acting in a religious capacity to exercise governmental power; or for the government to extend benefits to some religious entities and not others without adequate secular justification.

Neither can pass laws which aid one religion, aid all religions, or prefer one religion to another... in the words of Jefferson, the [First Amendment] clause against establishment of religion by law was intended to erect 'a wall of separation between church and State'.... That wall must be kept high and impregnable. We could not approve the slightest breach. At the core of the Establishment Clause lays the core principle of denominational neutrality. In Epperson v. Arkansas (1968) the Supreme Court outlined the broad principle of denominational neutrality mandated by the First Amendment: "Government in our democracy, state and national, must be neutral in matters of religious theory, doctrine, and practice.
