How does the first amendment protect religious freedom for American citizens?

The first amendment protects your freedom of speech, religion, press, assembly, and petition.

It contains the establishment clause, which prohibits the government from establishing a national religion, as well as the free exercise clause, which prohibits Congress from making any laws that restrict or prohibit a person's religious practices.

The First Amendment guarantees freedoms concerning religion, expression, assembly, and the right to petition. It forbids Congress from both promoting one religion over others and also restricting an individual's religious practices
