Here is a copy of the list of ineligible exempt persons:
(8) Ineligible businesses. A business engaged primarily in one or more of the following activities may not be treated as a non-listed business for purposes of this section: Serving as financial institutions or agents of financial institutions of any type; purchase or sale to customers of motor vehicles of any kind, vessels, aircraft, farm equipment or mobile homes; the practice of law, accountancy, or medicine; auctioning of goods; chartering or operation of ships, buses, or aircraft; gaming of any kind (other than licensed parimutuel betting at race tracks); investment advisory services or investment banking services; real estate brokerage; pawn brokerage; title insurance and real estate closing; trade union activities; and any other activities that may be specified by FinCEN. A business that engages in multiple business activities may be treated as a non-listed business so long as no more than 50% of its gross revenues are derived from one or more of the ineligible business activities listed in this paragraph (e)(8).
So, unless it's Bob's Church and Pawn where more than 50% of the revenue is from the pawn side, you can't exempt the church. On the other hand, if it's a small church in the country, with a small congregation, you'd have to wonder how they frequently deal in amounts > $10,000.
