The Secular Coalition works to increase visibility and respect for irreligious, nontheistic viewpoints in the United States and to protect and strengthen the secular character of the U.S. government. The Coalition advocates complete separation of church and state within American politics which they claim is clearly established in the U.S. Constitution under the First Amendment. Furthermore, the Coalition holds that freedom of conscience, which includes religious freedom, was of such importance that it was made the first of all freedoms protected in the Bill of Rights, and that reason and science should be guiding tenets for public policy.
