What are the rules on funding religious activity with Federal money?
The United States Supreme Court has said that faith-based organizations may not use direct government support to support "inherently religious" activities. Basically, it means you cannot use any part of a direct Federal grant to fund religious worship, instruction, or proselytization. Instead, organizations may use government money only to support the non-religious social services that they provide. Therefore, faith-based organizations that receive direct governmental funds should take steps to separate, in time or location, their inherently religious activities from the government-funded services that they offer.
