If you’re interested in Framing-era judicial thought on religious freedom, check out Muzzy v. Wilkins, 1 Smith’s (N.H.) 1 (1803) — a little-cited but very interesting case that illustrates how strong religious freedom and separation-of-church-and-state rhetoric and belief coexisted in at least some judicial minds of the era with strong support for certain kinds of government funding of religion. It’s not on Westlaw or Lexis, but you can find it using this Google Books query.
