42 C.F.R. § 54a.5
A religious organization that participates in an applicable program will retain its independence from Federal, State, and local governments and may continue to carry out its mission, including the definition, practice and expression of its religious beliefs. The organization may not expend funds that it receives directly from SAMHSA or the relevant State or local government to support any inherently religious activities, such as worship, religious instruction, or proselytization. Among other things, faith-based organizations may use space in their facilities to provide services supported by applicable programs, without removing religious art, icons, scriptures, or other symbols. In addition, a SAMHSA-funded religious organization retains the authority over its internal governance, and it may retain religious terms in its organization's name, select its board members on a religious basis, and include religious references in its organization's mission statements and other governing documents.
