In recording classical music on violin, to get a natural sound you're probably going to end up with the mic's a few feet away from the instrument.
My bad. For some reason, I was thinking this was about acoustic guitar recording.... Wow. So far off the mark. Yeah, for bowed string instruments, ignore everything I said... except that worrying about pickup pattern is focusing on the wrong problem---that's still true, just for different reasons. Specifically, miking bowed strings absolutely requires a decent room regardless of what you use to mic it, regardless of pickup pattern, etc. I've tried to record cello in small, somewhat reflective room and it was an unmitigated disaster. Moved into a larger room very quickly.

My advice would be to buy an inexpensive (but good) mic like the Naiant series and spend the money you save on starting to treat your room. Oh, wait, the original post was about recording in places like churches. For that, you're probably looking to pick up the room acoustics anyway. In that case, I'd probably go with a pair of cardioid mics like the MK-012 for a more natural (IMHO) stereo image.

But for recording a soloist at 3-4' in a giant space, that's about as good as it gets without being in a room specifically designed for good reverb.
