The First Amendment is the opening provision of the United States Bill of Rights. Its religion clauses limit government action in two related ways: government may not establish an official religion, and it may not prohibit the free exercise of religion. The same amendment also protects speech, publishing, peaceful assembly and petitions to government.

What the amendment says
The amendment begins with a restriction on Congress and then lists several connected freedoms. In modern constitutional discussion, the opening religion clauses are often called the Establishment Clause and the Free Exercise Clause.
Together, these protections support both religious participation and religious nonparticipation. They protect the ability to hold, change or reject religious beliefs, while limiting government preference among faiths or between religion and nonreligion.
Historical roots
The amendment emerged from earlier arguments about religious liberty in colonial and state governments. A major influence was Virginia's effort to protect freedom of conscience. Thomas Jefferson drafted a bill for religious freedom, and James Madison supported its passage through the Virginia legislature. The measure became law on 16 January 1786.
When the federal Constitution was drafted, it prohibited religious tests for federal office but did not initially contain a detailed list of individual rights. During the ratification debate, proposals for such protections gained support. Congress approved the Bill of Rights in 1789, and the amendments were ratified by the states in 1791.
How the wording developed
The final language followed several proposed formulations. Early drafts referred to equal rights of conscience, a national religion and the prevention of government interference with worship. The drafting process narrowed and refined the wording before the House and Senate agreed on the religion clauses.
Government neutrality and the “wall of separation”
The phrase “wall of separation” is commonly associated with Thomas Jefferson's explanation that government should not direct religious belief or worship. It is a useful description of one understanding of the Establishment Clause, although the constitutional meaning of the clause has been debated and developed over time.
Government neutrality does not require public institutions to erase the historical or cultural significance of religion. It does require public officials to distinguish educational discussion from religious instruction, and equal access from official endorsement. Public schools, courts and legislatures continue to address these boundaries in changing circumstances.
Key principles for readers
- Freedom of conscience: individuals may hold religious, nonreligious or changing convictions.
- Protection from establishment: government should not create an official faith or favor one religious position over another.
- Free exercise: people may practice religion, subject to the constitutional and legal framework governing public safety and the rights of others.
- Public participation: religious and nonreligious citizens may speak, assemble and petition government on equal terms.
- Historical context: constitutional language must be read alongside its history, later amendments, statutes and judicial interpretation.
