Murray v. Curlett is the 1963 U.S. Supreme Court case that, together with its companion case Abington School District v. Schempp, ended school-sponsored Bible reading and recitation of the Lord’s Prayer in American public schools. By a vote of 8-1, the Court held that these daily exercises violated the Establishment Clause of the First Amendment, even where students could be excused from participating with a parent’s written note.
The Baltimore Rule at the Center of the Case
The Board of School Commissioners of Baltimore City had required a religious opening exercise since 1905. As later amended, the rule read: “Each school, either collectively or in classes, shall be opened by the reading, without comment, of a chapter in the Holy Bible and/or the use of the Lord’s Prayer.” Catholic students could substitute the Douay translation, and any child could be excused on written request from a parent or guardian.1Legal Information Institute. 374 US 203 – School District of Abington Township, Pennsylvania, et al., v. Edward Lewis Schempp et al.
That opt-out did most of the work in the school board’s legal defense. On paper, no student was compelled to take part. In practice, asking to step out of the room singled a child out in front of classmates, and the rule had run largely unchallenged for more than half a century.
Who Brought the Case
Madalyn Murray and her son, William J. Murray III, were atheists living in Baltimore. They objected to the morning exercise not as members of a different faith but as people who rejected religious belief entirely. Because Maryland law required William to attend school, they argued, he had no real choice about being present when the ceremony took place. The opt-out did not solve the problem, in their view, because the government should not be sponsoring the ceremony at all.
They filed a petition in Maryland state court seeking a writ of mandamus, a court order that would force the school board to rescind the 1905 rule. The school board responded with a demurrer, and the trial court dismissed the petition without allowing an amendment. The Maryland Court of Appeals upheld that dismissal, finding Bible reading in public schools constitutional.2vLex United States. Murray v. Curlett
The Murrays then petitioned the U.S. Supreme Court, which was already considering the Schempp case out of Pennsylvania. That case challenged a state statute requiring daily Bible readings and raised nearly identical questions. The justices consolidated the two and decided them together.
What the Supreme Court Held
On June 17, 1963, the Court ruled 8-1 that government-sponsored Bible readings and recitations of the Lord’s Prayer in public schools violated the Establishment Clause, applied to state and local governments through the Fourteenth Amendment. Justice Tom C. Clark wrote the majority opinion covering both the Baltimore rule and the Pennsylvania statute.3Justia U.S. Supreme Court Center. School District of Abington Township, Pennsylvania v. Schempp
The holding was categorical. No state law or school board, Clark wrote, may require “that passages from the Bible be read or that the Lord’s Prayer be recited in the public schools of a State at the beginning of each school day — even if individual students may be excused from attending or participating in such exercises upon written request of their parents.”3Justia U.S. Supreme Court Center. School District of Abington Township, Pennsylvania v. Schempp That final clause did the heavy lifting. Both Baltimore and Pennsylvania had pointed to their opt-out provisions as proof that nobody was being coerced. The Court rejected that defense entirely.
The Purpose and Effect Test
Clark did more than strike down the practices. He articulated a standard for evaluating any law challenged under the Establishment Clause: “what are the purpose and the primary effect of the enactment? If either is the advancement or inhibition of religion then the enactment exceeds the scope of legislative power as circumscribed by the Constitution.” To survive, a law needed both a secular legislative purpose and a primary effect that neither advanced nor inhibited religion.4Legal Information Institute. Purpose and Effect Test Before Lemon
The Baltimore rule failed both prongs. Reading Bible passages aloud and reciting the Lord’s Prayer every morning had an obvious religious purpose, and the primary effect was to promote a particular religious tradition. The rule’s age was irrelevant. Constitutional limits apply regardless of how long a practice has existed.
Clark also emphasized neutrality. The government cannot take sides between religion and non-religion. It cannot use its authority to encourage prayer, and it cannot act with hostility toward faith either. Schools remained free to teach about religion in an academic context. What they could no longer do was conduct religious exercises as official school activities.
In 1971, the Court built on this framework in Lemon v. Kurtzman, adding a third requirement that a law must not foster excessive government entanglement with religion. The resulting three-part Lemon test governed Establishment Clause analysis for decades.5Justia U.S. Supreme Court Center. Lemon v. Kurtzman
Why the Opt-Out Did Not Save the Rule
Both Baltimore and Pennsylvania stressed that no student was forced to participate. The majority found this beside the point. The constitutional violation was not coercion of individual students but the government’s decision to sponsor a religious exercise in the first place. Whether one child or every child took part, the school board was still using public resources and official authority to promote a religious practice.3Justia U.S. Supreme Court Center. School District of Abington Township, Pennsylvania v. Schempp
This is where most confusion about the case persists. The ruling is often described as banning prayer in schools. It did not. Students remained free to pray privately at any time. What the decision prohibited was the school itself organizing, scheduling, and conducting the prayer as an institutional activity.
The Lone Dissent
Justice Potter Stewart dissented alone. His objection was not that school prayer was clearly constitutional but that the Court had moved too quickly on a thin record. Stewart called the cases “fundamentally deficient” because neither trial court had developed enough evidence about how the exercises actually operated day to day. Without knowing whether students felt real pressure to participate, he believed the Court could not make “an informed or responsible determination of the constitutional issues presented.”6Wikisource. Abington School District v. Schempp – Dissent Stewart
Stewart also raised a free exercise concern that cut the opposite way from the majority’s reasoning. Because the state compels children to attend school, he argued, banning all religious exercises could place “religion at an artificial and state-created disadvantage.” Allowing voluntary exercises, in his view, was the truly neutral position, and prohibiting them amounted to establishing “a religion of secularism.” He would have sent both cases back for further evidence-gathering.6Wikisource.

How the Ruling Extended Engel v. Vitale
The year before, in Engel v. Vitale (1962), the Court had struck down a 22-word nondenominational prayer composed by the New York Board of Regents and recited in public schools each morning. That 6-1 decision held that government officials writing an official prayer crossed a clear constitutional line.7United States Courts. Facts and Case Summary – Engel v. Vitale
Murray and Schempp presented a harder question. The prayers and readings at issue were not written by any government body. The Bible existed long before the Baltimore school board, and the Lord’s Prayer comes from Christian scripture rather than a state official’s pen. Defenders of the practice argued that Engel only reached prayers the government authored itself. The Court disagreed. The constitutional problem was not who wrote the words but the fact that the state organized and directed the religious exercise as part of the official school day. That reasoning closed the gap Engel had left open.
What Changed in Schools
The decision forced thousands of school districts to stop practices that had been routine for generations. Compliance was uneven, particularly in the rural South, where morning devotionals continued informally in some schools well into the 1970s and beyond. The political response was intense and durable. Proposed constitutional amendments to restore school prayer have been introduced in Congress repeatedly since 1963, though none have passed.
Sixty years on, Murray v. Curlett remains the anchoring precedent for the rule that public schools cannot sponsor religious exercises as part of the official school day, no matter how long the practice has been in place and no matter how easy the exit door.
