Establishment Clause

The First Amendment begins by forbidding laws "respecting an establishment of religion." At minimum, government may not create an official church, compel religious observance, or favor one faith over another. The clause also reaches less direct forms of government sponsorship, but it does not require public life to be stripped of every reference to religion. The central question is whether the challenged practice is attributable to government and, in context, amounts to establishment, coercion, or religious favoritism. That inquiry is different from asking whether a private person has chosen to speak or worship in a public setting.

Free Exercise Clause

The Free Exercise Clause protects the choice to hold religious beliefs and to practice a faith without hostile or discriminatory government treatment. Government may not prescribe religious belief, punish a person for belonging to a faith, or target conduct because it is religious. Belief itself receives the strongest protection. Conduct motivated by belief can still be regulated, however, because religious motivation does not place every action beyond ordinary law. The difficult cases ask whether government has adopted a genuinely neutral rule or has singled out religious exercise for a burden.

Separation of church and state

The Constitution does not contain the phrase "separation of church and state." The familiar wording comes from Thomas Jefferson's description of a "wall of separation." It captures an important principle: government may not establish an official faith, direct religious observance, or use public authority to favor religion. Yet the phrase can mislead if it is treated as a command to remove religious people, ideas, or organizations from every public setting. The First Amendment protects against establishment and protects free exercise. Constitutional neutrality is not hostility toward religion.

Religious expression in public institutions

A public institution is not a religion-free zone. Students, employees, and visitors retain rights of religious expression, subject to rules appropriate to their roles and the setting. The constitutional danger runs in both directions: an official may not use government authority to conduct a religious exercise, but an institution may not suppress a private religious viewpoint merely to avoid the appearance of religion. Attribution is the starting point. A teacher leading a class ordinarily speaks with school authority; a student praying quietly during free time ordinarily speaks privately.

School prayer

Public schools may teach students about religion, but they may not conduct religious exercises. A teacher cannot compose a prayer for the class, direct students to recite it, or ask school officials to select a devotional message for a ceremony. Describing participation as "voluntary" does not necessarily cure the problem. Students attend school under government authority, and young people may experience strong pressure to follow a teacher, coach, or principal even when an official says they may remain silent. The Establishment Clause analysis therefore focuses on government sponsorship and practical coercion, not merely on whether a written penalty exists.

Government aid to religion

A religious organization does not become ineligible for every public service or benefit because it is religious. Fire protection for a church, road maintenance near a mosque, and disability services for an eligible student can be supplied on the same terms available to others. Modern doctrine also permits many education and social-service benefits to reach religious providers when the government uses neutral eligibility rules and private people independently choose where to direct the benefit. The constitutional analysis asks how the program is designed and who makes the decisive choice, not simply whether money eventually reaches a religious institution.

Religious exemptions

An exemption excuses a religious claimant from a rule that otherwise applies. The federal Constitution does not require an exemption from every neutral, generally applicable law. Review becomes much more demanding when a law targets religious conduct, favors comparable secular activity, or contains individualized exceptions that officials refuse to extend to religious hardship. The comparison must fit the government's asserted interest; any secular exception is not automatically comparable.

Tests used in religion cases

Religion cases do not use one universal test. After Kennedy v. Bremerton School District, Establishment Clause interpretation proceeds by reference to historical practices and understandings while continuing to reject governmental coercion of religious observance. The older Lemon formula-secular purpose, principal effect, and excessive entanglement-matters historically, but it is not the Court's controlling general test.
