Interesting point. “Lapsed Catholic,” “secular Jew,” “backslidden Baptist,” or maybe “unregenerate Baptist.” I’m not sure about Lutherans ... “noncommunicating,” maybe?

Apple juice gives me the trots.

Yep, there are all kinds of terms for being “in but not of” when it comes to religions, but the “jack-Mormon” has to be my all-out favorite. ;o]

The term must come from "jackleg" which is an old southern term for somebody who isn't really qualified to do what they're doing.

As in "jackleg preacher", "jackleg carpenter" or "jackleg mechanic". Although an amateur mechanic is usually a "shade tree mechanic" = no shop, works under a shade tree.
