Final answer:
The First Amendment to the US Constitution guarantees the right to individual religious belief with two clauses: the Establishment Clause, which prevents the government from establishing a religion, and the Free Exercise Clause, which allows individuals to practice their religion freely.
Step-by-step explanation:
The First Amendment and Religious Freedom:
The part of the Constitution that guarantees the right to each person to believe whatever he or she chooses about religion is found in the First Amendment to the United States Constitution. This amendment explicitly states that 'Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.' This forms two core principles: the Establishment Clause, which prevents the government from establishing a national religion, and the Free Exercise Clause, which secures the right of individuals to practice their religion without interference from the government.
The Establishment Clause and the Free Exercise Clause together protect Americans' right to religious freedom, allowing them to freely express and exercise their beliefs. This has been an essential aspect of the nation's legal and cultural heritage since the Constitution's inception. Though interpretations and applications in law have evolved, the fundamental right to choose and practice one's religion remains a protected liberty in the United States.
