Yeah, a digital board seems a pretty scary concept based on most church situations I've seen. Usually the sound board is run by a layman in the church, someone who is not a sound guy by profession or training. And usually the sound board is set up and rarely messed with. Keeping it as close as possible to "cable into channel 1, pull up fader on channel 1" is usually a really good idea.
Some ministries are huge and have extensive sound systems. I've seen the facilities at the Crystal Cathedral in Garden Grove, Ca, and it's pretty impressive. Unfortunately, I wasn't able to get a look at what board they were using, but there are multiple speaker arrays around the cathedral, tons of mics, etc. Since they broadcast from there as well, I'm sure they use professionals to run the system. I could see a board with recall being essential for their operation.
But they are the exception. Usually it's a little mixer in a closet or off to the side that is generally set up once and then tinkered with occasionally.
