"They wouldn't even be able to pay to have the lawn mowed..."
Why would a church of 30 pay to have the lawn mowed? In my church, volunteers keep the place clean, mow the lawn, and pitch in to handle any maintenance that needs done (including roofing, plumbing, etc.). Thirty is more than enough to handle the job.
They MIGHT be able to handle mowing the lawn (actually, their kids would have to do it. If they have any kids, vide Bishopess Schori's riff on Episcopalians not having kids for the good of the planet.)
But it's the rare Episcopalian who can actually DO anything with his hands. And most of us who could, are not Episcopalians any more. It's the liberal whiners who are remaining behind. Think men with turtleneck sweaters and soft hands, women with short hair that looks like it was cut with the nail scissors, lots of clunky folk jewelry and (badly) hand knitted sweaters. All they can do is whine, so far as we have been able to determine none of them do any useful work.
(I'm only exaggerating a little bit. The most liberal crowd in almost any ECUSA church are the wine-and-croissant artsy bunch.)
Because they are all over 70 years old and their arthritis is too bad for them to be doing that sort of thing. Plus, they are used to paying others to do their manual work.
