I meant to add, I often would wonder how Ni would come out for Christians I think might be NJ's in our environment, which is heavy SJ. (Even the Berens book mentiones that we don't get much training in this kind of process int his society"). All of that "altered states of consciousness" would be looked on with suspicion, at least when put that way.
However, the people would likely simply attribute it to "God speaking to them" in normal "prayer"/meditation. (I tend to think that many Christians are trying, a bit unnaturally, to prolong the "divine intervention" they read about in scripture, in this age where "special revelation" has clearly ceased. This ends up producing this "inner"-focused religion, especially among Charismatics; and what they don't realize, is that rather than "testifying" to the rest of the world that it's really God working in them, it only "proves" to everyone that "God" is only some "inner" thing, and thus it doesn't really matter which religion one uses to access it).
So the point is, this is how their otherwise "unusual" form of perception would blend nicely into a heavy Si Christian environment. They'll probably be the ones more insistent that God really "speaks" to us, while the majority SJ's go through the motion because it's what we're "supposed" to do, but they'll be the ones to admit that it's hard to really hear what God says anew, and instead rely on the way he's "already spoken" to us in scripture. (Which I tended to fall back on, though with Ne in front, ponder on why direct revleation doesn't continue, and often gro weary of either of the other approaches, especially when neither has produced any consistent doctrinal unity).
