Americans United for Separation of Church and State is a nonpartisan educational and advocacy organization dedicated to advancing the separation of religion and government as the only way to ensure freedom of religion, including the right to believe or not believe, for all. We use high-impact litigation, powerful lobbying and grassroots advocacy to ensure that religion does not dictate public policy, the government does not tell Americans what to believe or how to practice their faith, and discrimination is not justified under the guise of religion.
