The First Amendment to the United States Constitution prevents the government from making laws respecting an establishment of religion; prohibiting the free exercise of religion; or abridging the freedom of speech, the freedom of the press, the freedom of assembly, or the right to petition the government for redress of grievances. It was adopted on December 15, 1791, as one of the ten amendments that constitute the Bill of Rights.
Engel v. Vitale, 370 U.S. 421 (1962), was a landmark United States Supreme Court case in which the Court ruled that it is unconstitutional for state officials to compose an official school prayer and encourage its recitation in public schools, due to violation of the First Amendment. The ruling has been the subject of intense debate.
"Separation of church and state" is a metaphor paraphrased from Thomas Jefferson and used by others in discussions regarding the Establishment Clause and Free Exercise Clause of the First Amendment to the United States Constitution which reads: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof..."
The Blaine Amendment was a failed amendment to the U.S. Constitution that would have prohibited direct government aid to educational institutions that have a religious affiliation. Most state constitutions already had such provisions, and thirty-eight of the fifty states have clauses that prohibit taxpayer funding of religious entities in their state constitutions.
Everson v. Board of Education, 330 U.S. 1 (1947), was a landmark decision of the United States Supreme Court that applied the Establishment Clause of the First Amendment to state law. Before this decision, the clause, which states, "Congress shall make no law respecting an establishment of religion", imposed limits only on the federal government, while many states continued to grant certain religious denominations legislative or effective privileges.
In United States law, the Establishment Clause of the First Amendment to the United States Constitution, together with that Amendment's Free Exercise Clause, form the constitutional right of freedom of religion. The relevant constitutional text is:
Congress shall make no law respecting an establishment of religion...
The Free Exercise Clause accompanies the Establishment Clause of the First Amendment to the United States Constitution. The Establishment Clause and the Free Exercise Clause together read:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof...
Zelman v. Simmons-Harris, 536 U.S. 639 (2002), was a 5–4 decision of the United States Supreme Court that upheld an Ohio program that used school vouchers. The Court decided that the program did not violate the Establishment Clause of the First Amendment, as long as parents using the program were allowed to choose among a range of secular and religious schools.
Cutter v. Wilkinson, 544 U.S. 709 (2005), was a United States Supreme Court case in which the Court held that, under the Religious Land Use and Institutionalized Persons Act (RLUIPA), facilities that accept federal funds cannot deny prisoners accommodations that are necessary to engage in activities for the practice of their own religious beliefs.
McCollum v. Board of Education, 333 U.S. 203 (1948), was a landmark United States Supreme Court case related to the power of a state to use its tax-supported public school system to aid religious instruction. The case was a test of the separation of church and state with respect to education.
Cantwell v. Connecticut, 310 U.S. 296 (1940), is a landmark court decision by the United States Supreme Court holding that the First Amendment's federal protection of religious free exercise incorporates via the Due Process Clause of the Fourteenth Amendment and so applies to state governments too.
Sherbert v. Verner, 374 U.S. 398 (1963), was a case in which the Supreme Court of the United States held that the Free Exercise Clause of the First Amendment required the government to demonstrate both a compelling interest and that the law in question was narrowly tailored before it denied unemployment compensation to someone who was fired because her job requirements substantially conflicted with her religion.
Rosenberger v. Rector and Visitors of the University of Virginia, 515 U.S. 819 (1995), was an opinion by the Supreme Court of the United States regarding whether a state university might, consistent with the First Amendment, withhold from student religious publications funding provided to similar secular student publications. The University of Virginia provided funding to every student organization that met funding-eligibility criteria, which Wide Awake, the student religious publication, fulfilled. The university's defense claimed that denying student activity funding to the religious magazine was necessary to avoid the University's violating the Establishment Clause of the First Amendment.
Hein v. Freedom From Religion Foundation, 551 U.S. 587 (2007), was a decision by the United States Supreme Court which ruled that taxpayers do not have the right to challenge the constitutionality of expenditures by the executive branch of the government. The issue was whether taxpayers have the right to challenge the existence of the White House Office of Faith-Based and Community Initiatives. The case centered on three Supreme Court precedents: Flast v. Cohen, Bowen v. Kendrick, and Valley Forge Christian College v. Americans United for Separation of Church & State.
Texas Monthly v. Bullock, 489 U.S. 1 (1989), was a case brought before the US Supreme Court in November 1988. The case was to test the legality of a Texas statute that exempted religious publications from paying state sales tax.
Bowen v. Kendrick, 487 U.S. 589 (1988), was a United States Supreme Court case in which the Court upheld the constitutionality of the Adolescent Family Life Act.
School prayer in the United States if organized by the school is largely banned from public elementary, middle and high schools by a series of Supreme Court decisions since 1962. Students may pray privately, and join religious clubs in after-school hours. Public schools are those operated by government agencies, such as local school districts. They are banned from conducting religious observances such as prayer. Private and parochial schools are not covered by these rulings, nor are colleges and universities. Elementary and secondary schools are covered because students are required to attend, and are considered more at risk from official pressure than are older students and adults. The Constitutional basis for this prohibition is the First Amendment to the United States Constitution, which requires that:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof ...
Trinity Lutheran Church of Columbia, Inc. v. Comer, 582 U.S. ___ (2017), was a case in which the Supreme Court of the United States held that a Missouri program that denied a grant to a religious school for playground resurfacing, while providing grants to similarly situated non-religious groups, violated the freedom of religion guaranteed by the Free Exercise Clause of the First Amendment to the United States Constitution.
Espinoza v. Montana Department of Revenue, 591 U.S. ___ (2020), was a landmark United States Supreme Court case in which the Court ruled that a state-based scholarship program that provides public funds to allow students to attend private schools cannot discriminate against religious schools under the Free Exercise Clause of the Constitution.
Carson v. Makin, 596 U.S. ___ (2022), was a landmark United States Supreme Court case related to the First Amendment to the United States Constitution and the Free Exercise Clause. It was a follow-up to Espinoza v. Montana Department of Revenue.
