We have several churches of this description in our Presbytery. The given answer is that they are aging with being in rural settings with the ever declining population. But, probably a more valid answer is that the churches had an history of always looking inward, and didn't see the need for outreach. Also, the Reformed has a problem with today's culture. It is not about teaching and learning, but being able to express oneself and be entertained.
