TEXT OF CONSTITUTION
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
The first amendment protects religious freedom by prohibiting the establishment of an official or exclusive church or sect. Free speech and free press are protected, although they can be limited for reasons of defamation, obscenity, and certain forms of state censorship, especially during wartime. The freedom of assembly and petition also covers marching, picketing and pamphleteering.
