Its purposes, as stated in its bylaws, are to promote the separation of church and state and to educate the public on matters relating to atheism, agnosticism and nontheism. The FFRF publishes Freethought Today, the only freethought newspaper in North America. The organization pursues public-interest lawsuits and engages in public debates to further its goals. Since 2006, the Foundation has produced the Freethought Radio show, currently the only national freethought radio broadcast in the United States.
