Which amendment protects the right to free exercise of religion?

The First Amendment is the cornerstone of civil liberties in the United States and explicitly protects several fundamental rights, including the right to free exercise of religion. Its language states that Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof. This means individuals are free to practice their religion without interference from the government, making it a vital aspect of personal freedom and expression.

The other amendments listed do not focus on religious freedoms. The Second Amendment deals with the right to bear arms, the Third Amendment addresses the quartering of soldiers, and the Fourth Amendment protects against unreasonable searches and seizures. Each of these amendments serves a different purpose in the Bill of Rights and does not have anything to do with the exercise of religion.
