Which freedom is guaranteed by the First Amendment?

The First Amendment of the United States Constitution protects several fundamental freedoms that are essential to the democratic process. Among these, the freedom of religion is a critical component. This amendment ensures that individuals have the right to practice any religion they choose or to practice no religion at all, free from government interference. This protection helps to foster a society where diverse beliefs can coexist and where individuals can express their conscience without fear of persecution.

While the First Amendment indeed encompasses many rights, including freedom of speech and freedom of assembly, the most direct connection to the question highlights the importance of religious liberty as a cornerstone of American democracy. It is important to recognize that these clauses work together to create a robust framework for individual rights, but the question focuses specifically on what is explicitly guaranteed by the First Amendment, which includes the protection of religious beliefs and practices.
