(b) A faith-based organization may not use direct Federal financial assistance from HHS to support or engage in any explicitly religious activities (including activities that involve overt religious content such as worship, religious instruction, or proselytization) except when consistent with the Establishment Clause of the First Amendment and any other applicable requirements. Such an organization also may not, in providing services funded by the Department, or in their outreach activities related to such services, discriminate against a program beneficiary or prospective program beneficiary on the basis of religion, a religious belief, a refusal to hold a religious belief, or a refusal to attend or participate in a religious practice.
