Separation of Church and State is a phrase that refers to the Establishment Clause of the First Amendment. The phrase dates back to the early days of U.S. history, and Thomas Jefferson referred to the First Amendment as creating a “wall of separation” between church and state as the third president of the U.S. The term is also often employed in court cases. For example, U.S. Supreme Court Justice Hugo Black famously stated in Everson v. Board of Education that “[t]he First Amendment has erected a wall between church and state,” and “[t]hat wall must be kept high and impregnable.”

Although the words “separation of church and state” do not appear in the First Amendment, the establishment clause was intended to separate church from state. When the First Amendment was adopted in 1791, the establishment clause applied only to the federal government, prohibiting the federal government from any involvement in religion. By 1833, all states had disestablished religion from government, providing protections for religious liberty in state constitutions. In the 20th century, the U.S. Supreme Court applied the establishment clause to the states through the 14th Amendment. Today, the establishment clause prohibits all levels of government from either advancing or inhibiting religion.
The establishment clause separates church from state, but not religion from politics or public life. Individual citizens are free to bring their religious convictions into the public arena. But the government is prohibited from favoring one religious view over another or even favoring religion over non-religion.
Our nation’s founders disagreed about the exact meaning of “no establishment” under the First Amendment; the argument continues to this day. But there was and is widespread agreement that preventing government from interfering with religion is an essential principle of religious liberty. All of the Framers understood that “no establishment” meant no national church and no government involvement in religion. Thomas Jefferson and James Madison believed that without separating church from state, there could be no real religious freedom.
The first use of the “wall of separation” metaphor was by Roger Williams, who founded Rhode Island in 1635. He said an authentic Christian church would be possible only if there was “a wall or hedge of separation” between the “wilderness of the world” and “the garden of the church.” Any government involvement in the church, he believed, corrupts the church.
Then in 1802, Thomas Jefferson, in a letter to the Danbury Baptist Association, wrote: “I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should ‘make no law respecting an establishment of religion, or prohibiting the free exercise thereof,’ thus building a wall of separation between Church and State.”
The Supreme Court has cited Jefferson’s letter in key cases, beginning with a polygamy case in the 19th century. In the 1947 case Everson v. Board of Education, the Court cited a direct link between Jefferson’s “wall of separation” concept and the First Amendment’s establishment clause.

The first clause in the Bill of Rights states that “Congress shall make no law respecting an establishment of religion.”
Establishment clause of First Amendment often interpreted to require separation of church and state
For approximately the first 150 years of the country’s existence, there was little debate over the meaning of this clause in the Constitution. As the citizenry became more diverse, however, challenges arose to existing laws and practices, and eventually, the Supreme Court was called upon to determine the meaning of the establishment clause.
Though not explicitly stated in the First Amendment, the clause is often interpreted to mean that the Constitution requires the separation of church and state.
'Separation of church and state' metaphor rooted in early American fears of government involvement
Roger Williams, founder of Rhode Island, was the first public official to use this metaphor. He opined that an authentic Christian church would be possible only if there was “a wall or hedge of separation” between the “wilderness of the world” and “the garden of the church.” Williams believed that any government involvement in the church would corrupt the church.
The most famous use of the metaphor was by Thomas Jefferson in his 1802 letter to the Danbury Baptist Association. In it, Jefferson declared that when the American people adopted the establishment clause they built a “wall of separation between the church and state.”
Jefferson had earlier witnessed the turmoil of the American colonists as they struggled to combine governance with religious expression. Some colonies experimented with religious freedom while others strongly supported an established church.
Jefferson fought to disestablish Anglican church in Virginia colony
One of the decisive battlegrounds for disestablishment was Jefferson’s colony of Virginia, where the Anglican Church had long been the established church.
Both Jefferson and fellow Virginian James Madison felt that state support for a particular religion or for any religion was improper. They argued that compelling citizens to support through taxation a faith they did not follow violated their natural right to religious liberty. The two were aided in their fight for disestablishment by the Baptists, Presbyterians, Quakers, and other “dissenting” faiths of Anglican Virginia.
During the debates surrounding both its writing and its ratification, many religious groups feared that the Constitution offered an insufficient guarantee of the civil and religious rights of citizens. To help win ratification, Madison proposed a bill of rights that would include religious liberty.
As presidents, though, both Jefferson and Madison could be accused of mixing religion and government. Madison issued proclamations of religious fasting and thanksgivings while Jefferson signed treaties that sent religious ministers to the Native Americans. And from its inception, the Supreme Court has opened each of its sessions with the cry “God save the United States and this honorable court.”
Public school religion cases allow Supreme Court to define establishment clause protection
It was not until after World War II that the Court interpreted the meaning of the establishment clause.
In Everson v. Board of Education (1947), the Court held that the establishment clause is one of the liberties protected by the due process clause of the Fourteenth Amendment, making it applicable to state laws and local ordinances. Since then the Court has attempted to discern the precise nature of the separation of church and state.
In 1971 the Court considered the constitutionality of a Pennsylvania statute that provided financial support to nonpublic schools for teacher salaries, textbooks, and instructional materials for secular subjects and a Rhode Island statute that provided direct supplemental salary payments to teachers in nonpublic elementary schools.
Lemon test developed to vet laws dealing with religious establishment
In Lemon v. Kurtzman (1971), the Court established a three-pronged test for laws dealing with religious establishment. To be constitutional a statute must have “a secular legislative purpose,” it must have principal effects that neither advance nor inhibit religion, and it must not foster “an excessive government entanglement with religion.”
Twenty-six years later the Court modified the Lemon test in Agostini v. Felton (1997) by combining the last two elements, leaving a “purpose” prong and a modified “effects” prong.
In County of Allegheny v. American Civil Liberties Union (1989), a group of justices led by Justice Anthony M. Kennedy in his dissent developed a coercion test: the government does not violate the establishment clause unless it provides direct aid to religion in a way that would tend to establish a state church or involve citizens in religion against their will.
Endorsement test used in cases involving religious displays on public property
Justice Sandra Day O’Connor proposed an endorsement test that asks whether a particular government action amounts to an endorsement of religion.
In Lynch v. Donnelly (1984), O’Connor noted that the establishment clause prohibits the government from making adherence to a religion relevant to a person’s standing in the political community. Her fundamental concern was whether government action conveyed a message to non-adherents that they are outsiders. The endorsement test is often invoked in religious display cases.
In McCreary County v. American Civil Liberties Union (2005), the Court ruled that the display of the Ten Commandments in two Kentucky courtrooms was unconstitutional but refused in the companion case, Van Orden v. Perry (2005), to require the removal of a long-standing monument to the Ten Commandments on the grounds of the Texas State Capitol.
Court says in neutrality test that government must treat religous groups the same
Questions involving appropriate use of government funds are increasingly subject to the neutrality test, which requires the government to treat religious groups the same as it would any other similarly situated group.
In a test of Ohio’s school voucher program, the Court held 5-4 in Zelman v. Simmons-Harris (2002) that Ohio’s program is part of the state’s general, neutral undertaking to provide educational opportunities to children and does not violate the establishment clause. In his opinion for the majority, Chief Justice William H. Rehnquist wrote that the “Ohio program is entirely neutral with respect to religion.”
More recently, in 2022, the Supreme Court ruled 6-3 in Carson v. Makin that Maine could not exclude families who send their children to religious schools from its state-funded tuition reimbursement program. The program helped children who live in rural areas without public schools nearby, but said the tuition could not be used for religious schools. The court, in a ruling written by Justice John Roberts Jr., said that the policy violated the parents' right to freely exercise their religion and that a public benefit that flowed to a religious school based on a parent's choice did not "offend" the establishment clause of the First Amendment.
From the colonial era to the present, religions and religious beliefs have played a significant role in the political life of the United States. Religion has been at the core of some of the best and worst movements in the country’s history. As religious diversity continues to grow, concerns about separation of church and state are likely to continue.
