Establishment of Irreligion

The Establishment Clause of the First Amendment prohibits the establishment of a national religion by Congress or the preference of one religion over another, or religion over non-religion.

Board of Education of Kiryas Joel Village School District v. Grumet, 512 U.S. 687 (1994), Justice David Souter, writing for the majority, concluded that "government should not prefer one religion to another, or religion to irreligion."
