Final answer:
The religion clauses of the First Amendment prohibit the establishment of a national religion, favoring one religious sect over another, and hindering individuals' exercise of religion.
Step-by-step explanation:
The religion clauses of the First Amendment serve to bar the government from establishing a national religion, bar the government from favoring one religious sect over another, and ensure the government does not hinder individuals' exercise of religion.
These clauses are part of the First Amendment to the United States Constitution, which states, 'Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof...'
By prohibiting the establishment of a national religion and ensuring religious freedom, the First Amendment protects the separation of church and state and promotes religious tolerance in the United States.
