Thanks for bringing this topic up. I think this quote gets at the constructive crux of this issue:

"How can the church raise assets for local economies rather than find ways to break even in order to maintain payrolls and property costs? How does the church add value to local economies rather than absorb value from those economies? "

For starters, we should give more scrutiny to what happens during most stewardship campaigns held about this time of year in Presbyterian churches. As someone who is now a young adult and grew up "unchurched", I think the pledge generally assumes alot about how and why people give which may prove increasingly irrelevant with the coming my generations of givers. The very idea of the pledge pitch reminds me of the typical public tv or radio pledge drive which for many becomes either irritating or simply "ho hum". Rather than simply make the same narrow case for its wares that every charity, school, or non-profit makes with its "why I give" messages and colorful book of envelopes, why not attempt to offer something alittle more comprehensive even daring?

Instead of dealing with the 2nd order issue of how much people will give to the church, how about dealing with the 1st order issues of how to think about money, the variety of ways to budget, and a theologically driven posture toward giving. With available resources of teaching, discussion and technology, we could be a clearinghouse for people to discern quality and quantity of all their giving, even if its not just giving to us. The upside of that is having helped people address 1st order issues of economics, they might be more inclined to actually give to church.

That's just one idea. I continue to search and struggle for ways to connect these dots and answer the question you posed.
