⚖️ What the Constitution Says: The First Amendment of the U.S. Constitution includes the Establishment Clause, which prohibits the government from establishing or favoring a religion. This clause has been the foundation of numerous Supreme Court rulings that limit religious expression in public schools.
In cases such as Stone v. Graham (1980), the Court ruled that requiring the Ten Commandments to be displayed in classrooms was unconstitutional. Justices have consistently found that such mandates violate the separation of church and state, reinforcing that public institutions must remain neutral in matters of religion.
