Is there yet a list of all religious groups that get exemptions?
No, all that people are going on is the wording of this part of Chapter 48 Section 5000:
(d) Applicable Individual- For purposes of this section--
`(1) IN GENERAL- The term `applicable individual' means, with respect to any month, an individual other than an individual described in paragraph (2), (3), or (4).
`(2) RELIGIOUS EXEMPTIONS-
`(A) RELIGIOUS CONSCIENCE EXEMPTION- Such term shall not include any individual for any month if such individual has in effect an exemption under section 1311(d)(4)(H) of the Patient Protection and Affordable Care Act which certifies that such individual is a member of a recognized religious sect or division thereof described in section 1402(g)(1) and an adherent of established tenets or teachings of such sect or division as described in such section.
To check out the various sections mentioned go to Thomas.gov & search for HR 3590.
FWIW, I couldn't find section 1402 (g) (1). It seems to stop at (f).
