Welcome to AU.org

I'm Barry W. Lynn, executive director of Americans United.

2007 marks the 60th anniversary of the establishment of Americans United as one of the foremost defenders of the separation of church and state, the cornerstone of religious liberty in America. We are proud to celebrate 60 years of freedom and look forward to continuing our work for many years to come.

As a non-sectarian, non-partisan organization, AU's membership includes Christians, Jews, Buddhists, people with no religious affiliation and others. Democrats, Republicans and independents have joined our ranks.

Americans United is an independent organization with no ties to any larger group or political movement. We are a true grassroots organization. Thanks to your support, Americans United is able to defend separation of church and state in the courts, educate legislators, work with the media to inform Americans about religious freedom issues and organize local chapters all over the country.

I welcome your feedback about anything you read on our Web site. I'd also like to hear your suggestions for making the site even better. Please don't hesitate to contact us and share your thoughts.

Thanks again for visiting AU online.
