The Evolving “Wall”: Recent Supreme Court Decisions Reshaping Religious Expression in Schools

In the landscape of American education, few issues spark as much debate as the role of religion in public schools. Recent Supreme Court decisions have thrust this tension into the spotlight, challenging long-held assumptions about the “wall of separation between Church & State.” Take, for instance, the 2022 case of Kennedy v. Bremerton School District. Joseph Kennedy, a high school football coach in Washington state, made it a habit to kneel at the 50-yard line after games for a brief, personal prayer. What began as a solitary act soon drew students and even opposing team members to join him voluntarily. The school district, fearing Kennedy’s personal prayers violated the Establishment Clause of the First Amendment by appearing to endorse religion, suspended Kennedy and declined to renew his contract. Kennedy sued, claiming violations of his free speech and free exercise rights. In a landmark 6-3 decision, the Supreme Court sided with him, ruling that his prayers were private expressions protected by the First Amendment, not official school actions that coerced participation. 

This ruling was not isolated. Just three years earlier, in American Legion v. American Humanist Association (2019), the Court upheld that the Bladensburg Peace Cross (a 32-foot-tall Latin cross serving as a World War I memorial on public land in Maryland) did not violate the First Amendment’s Establishment Clause and was therefore constitutional. The cross was erected on private land in 1925, but the Maryland-National Capital Park and Planning Commission acquired the land and the cross four decades later. The Commission used public funds to maintain the monument ever since. In a 7-2 decision reversing a lower court’s finding, the Court upheld the monument’s presence and public maintenance, emphasizing its longstanding historical significance as a secular tribute to fallen soldiers rather than an endorsement of religion, notwithstanding its Christian symbolism. Despite arguments that the cross symbolized Christian favoritism, the justices emphasized the monument’s historical significance and secular purposes over time, such as honoring fallen soldiers. 

These more recent cases stand in stark contrast to earlier precedents. For example, in Stone v. Graham (1980), the Court struck down a Kentucky law requiring the posting of the Ten Commandments in public school classrooms, deeming it a religious endorsement lacking secular purpose. Similarly, Lee v. Weisman (1992) banned clergy-led prayers at public school graduations, citing the coercive pressure on students in a captive audience. And in Santa Fe Independent School District v. Doe (2000), even student-initiated prayers over stadium loudspeakers were ruled unconstitutional due to perceived government endorsement.

These modern shifts highlight a broader transformation in how the judiciary interprets religious liberty in educational contexts. Schools, as microcosms of society, grapple with diverse student populations where expressions of faith can foster inclusion or breed exclusion. A 2025 survey by the Pew Research Center found that 52% of Americans favored public school teachers to lead their classes in prayers that refer to Jesus. Yet, minority religious groups and nonbelievers often voice concerns about subtle pressures. Indeed, in a 2025 federal case, Rabbi Nathan v. Alamo Heights Independent School District, a Jewish rabbi and students successfully obtained a preliminary injunction against enforcement of a Texas statute that required displaying the Ten Commandments in public school classrooms, arguing the mandate created coercive subtle pressure on minority religious groups and nonbelievers to conform to a state-endorsed religious message. Such examples illustrate the ongoing tug-of-war: How can schools accommodate personal faith without implying state sponsorship?

This evolution reflects a broader change in judicial interpretation of the First Amendment’s Establishment Clause, which bars government establishment of religion. The Court’s approach has moved away from a strict separationist stance which has been long symbolized by Thomas Jefferson’s “wall of separation” metaphor toward a framework that places greater emphasis on historical practices, the absence of direct coercion, and stronger safeguards for individual free exercise rights, especially within public school environments. 

Historical Foundations: From Madison and Jefferson to the First Amendment

To understand this progression, we must rewind to the nation’s founding. The seeds of religious liberty were sown amid colonial debates over state-supported churches. In Virginia during the late 18th century, disestablishment efforts dismantled the Anglican Church’s privileged status. James Madison’s “Memorial and Remonstrance Against Religious Assessments” (1785) was a pivotal document. Written in opposition to Patrick Henry’s bill proposing taxes to fund Christian teachers, Madison argued that religion must remain exempt from civil authority. “The Religion then of every man must be left to the conviction and conscience of every man,” he wrote, warning that government involvement corrupts faith and breeds inequality. Madison emphasized that true religion flourishes without state aid, foreshadowing the First Amendment’s protections.

Thomas Jefferson complemented Madison’s efforts with the Virginia Statute for Religious Freedom (1786), which Madison helped pass. This statute declared that “no man shall be compelled to frequent or support any religious worship, place, or ministry whatsoever,” and protected free belief without civil penalties. The statute barred religious tests for office and discrimination based on faith, directly influencing the federal Constitution. These documents reflected Enlightenment ideals of uncoerced conscience, where faith is a private matter between individuals and their deity.

The Bill of Rights, ratified in 1791, enshrined these principles. Anti-Federalists, fearing a strong central government might infringe on liberties, demanded amendments. Madison, initially skeptical, drafted most of them in response. The First Amendment’s text is concise yet profound: 

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

The Establishment Clause prevents government favoritism toward religion, while the Free Exercise Clause safeguards personal practice, provided it does not violate neutral laws.

The Rise of the “Wall of Separation” Metaphor and Early Supreme Court Citations

Religion’s role in early American politics came to a head in the 1800 presidential election. Federalists, dominant in pious New England, smeared Jefferson as an atheist or deist intent on dismantling Christianity. Newspapers and clergy warned that his victory would shutter churches and usher in godless anarchy, echoing fears from the French Revolution. Indeed, it is reported that some women in New England even buried their family bibles to ensure that they would not be confiscated by Jefferson’s government. In Connecticut, where Congregationalism held sway as the church established by the State of Connecticut, Baptist dissenters faced discrimination. The October 1801 letter from the Danbury Baptists to the newly elected Jefferson lamented that religious privileges were mere “favors.” 

The Danbury Baptists’ letter highlighted that Connecticut’s state constitution lacked explicit protections for religious liberty, leaving religion vulnerable to legislative control rather than safeguarding it as an individual right. As a religious minority, they objected to enjoying religious freedoms only as revocable favors from the state rather than as inalienable rights, which forced them into humiliating acknowledgments like certificates and taxes. They expressed deep concern that unchecked government power could enable oppression under the guise of religion, insisting that civil authority must never intrude on matters of conscience or Christ’s kingdom, and should instead be limited to protecting citizens from harm while preserving free exercise of religion.

President Jefferson’s letter to the Danbury Baptists a couple months later immortalized the “wall of separation” metaphor. Jefferson responded:

Believing with you that religion is a matter which lies solely between Man & his God, that he owes account to none other for his faith or his worship, that the legitimate powers of government reach actions only, & not opinions, 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 & State.

This phrase, initially a political gesture to reassure religious minorities, lay dormant for decades. Published in Jefferson’s collected works in the mid-19th century, the letter gained traction after the Fourteenth Amendment was ratified after the Civil War applying Bill of Rights (and the First Amendment) to the individual states. 

The Supreme Court first cited Jefferson’s response to the Danbury Baptists in Reynolds v. United States (1878), a polygamy case, to distinguish government regulation of actions from regulation of beliefs. But the letter later became precedent in Everson v. Board of Education (1947), where Justice Hugo Black invoked the “wall” to uphold reimbursing parents for busing children to parochial schools, while affirming strict separation. “The First Amendment has erected a wall between church and state. That wall must be kept high and impregnable,” Black declared. The following year, McCollum v. Board of Education (1948) struck down released-time religious instruction in public schools, reinforcing that government cannot aid religious groups.

The Lemon Test Era: Strict Separation in Educational Settings

This separationist era peaked with Lemon v. Kurtzman (1971). Pennsylvania and Rhode Island laws funded salaries and materials for secular subjects in religious schools. The Court, in a near unanimous decision, invalidated them under a new three-prong test. Pursuant to the “Lemon Test,” statutes must have a legitimate secular purpose, its primary effect must neither advance nor inhibit religion, and it must avoid excessive entanglement between government and religion. Chief Justice Warren Burger reasoned that ongoing oversight to ensure funds were not used religiously would entangle state and church, risking political division. The Lemon Test became the benchmark for Establishment Clause cases, especially in schools.

Subsequent rulings applied the Establishment Clause stringently. In Stone v. Graham (1980), posting the Ten Commandments failed the secular purpose prong. Wallace v. Jaffree (1985) invalidated Alabama’s moment-of-silence law for meditation or prayer, as it lacked genuine secular intent. Lee v. Weisman (1992) focused on coercion, ruling that even nonsectarian graduation prayers pressured students. In Santa Fe Independent School District, discussed previously, the Court extended this ruling to student-led prayers at football games, citing the school’s facilitation as endorsement.

However, cracks in this framework emerged. By the late 20th century, Supreme Court justices critiqued Lemon as overly hostile to religion. In addition, a 1998 analysis by Library of Congress historian James Hutson, aided by FBI forensics on Jefferson’s draft letter, revealed Jefferson’s heavy edits to his letter to the Danbury Baptists. Jefferson crossed out phrases like “eternal separation,” suggesting that Jefferson’s wall metaphor was a tactical response to Federalist attacks and not a rigid doctrine. Hutson called the letter a “political manifesto,” sparking debate. Religious groups argued Jefferson’s draft of the letter undermined strict separation arguments, while critics saw Hutson’s analysis as politicizing history. 

The tide turned decisively in recent years. In American Legion, discussed supra, the Court preserved the Bladensburg Peace Cross, prioritizing its 100-year history and secular meanings over Lemon. Justice Samuel Alito noted that longstanding monuments acquire nonreligious significance. The final blow came in Kennedy v. Bremerton School District. Justice Neil Gorsuch’s majority opinion abandoned Lemon and its endorsement tests, opting for “historical practices and understandings.” Coach Kennedy’s prayers were deemed personal, occurring when coaches handled private matters, without coercing students. “The Constitution neither mandates nor permits the government to suppress such religious expression,” Gorsuch wrote.

This new approach has profound implications for schools. In Oklahoma Statewide Charter School Board v. Drummond (2025), the Supreme Court addressed whether a state could approve a fully Catholic curriculum charter school funded by public dollars. In a 4-4 tie (Justice Barrett recused), the Court affirmed the decision without opinion, preserving the ban on religious public charter schools in Oklahoma. The outcome underscores that, despite greater accommodation of private religious expression in cases like Kennedy, the Court has not yet permitted overtly religious entities to function as government-funded public schools, maintaining key limits on state endorsement of religion in core public education. 

The Delicate Balance between Teacher Religious Expression and School Neutrality

Balancing teacher discretion with neutrality in public schools is profoundly challenging. Teachers are both individuals with First Amendment rights to free expression and state employees whose actions carry official authority before students. The Supreme Court’s post-Kennedy shift toward historical practices and actual coercion has expanded leeway for private expression but blurred the line between personal and official conduct, forcing schools to navigate case-by-case boundaries. Administrators are tasked with safeguarding teachers’ religious liberty while maintaining an inclusive, neutral environment. This enduring tension reflects the First Amendment’s core challenge in education of protecting genuine faith expression without subtly establishing religion in pluralistic public spaces.
