Which Religious Organizations Count as Religious?

The Federalist Society

The definitions of religious organizations that the federal government is deploying in the context of the mandate, which requires health plans to cover a wide range of contraceptive services, have great religious-freedom significance not only because they will determine which religious freedom and conscience claims will be honored, and to what degree, but because they embody a governmental conception of what is authentic religion. 

That evident conception has proven to be greatly troubling to many religious organizations, both houses of worship and faith-based service organizations.
