Under the 1st Amendment, how is religion defined?

The First Amendment to the United States Constitution guarantees freedoms concerning religion. It prohibits Congress from establishing a religion (the Establishment Clause) and protects the free exercise of religion (the Free Exercise Clause). Under this framework, the definition of religion is rooted in the idea that individuals have the right to worship any deity, follow any spiritual belief, or choose not to engage in religion at all. This definition emphasizes personal autonomy and the pluralistic nature of belief in the U.S., which encompasses a diverse array of religious practices and non-beliefs.

The other options contradict the principles outlined in the First Amendment. Promoting one religion over another would violate the Establishment Clause, which requires the government to remain neutral in religious matters. Mandating attendance at religious services or participation in religious practices infringes upon individuals' rights to practice their beliefs freely or to abstain from any religious activity altogether. The First Amendment's protection allows for personal and diverse expressions of faith without coercion or governmental influence.
