Bill,
I'm interested to see if there are significant variations between different denominations, and yes, that will take awhile. I plan on continuing to work on this, but won't likely be devoting the same concentration of time I have the past 3 months or so.
As far as a Vineyard-ish theology of work, I don't think we really have one at the moment, though the general "Kingdom of God / already but not yet" gives the potential to combine a protological theology of work with an eschatological yearning with a recognition of the continuing reality of the fall, or at least a starting point to combine the reality of the fall with eschatological hopes. Maybe what it's missing is a way to tie it all back to original Genesis creation mandates, which I think is essential for a balanced theology of work.
I am kind of trying to work my way slowly down that path, particularly with my second paper, but it was just a start. As I go through this, I have lots of areas for which I continually need to improve my knowledge to be able to continue fruitful inquiry. I probably need to dig more into "Kingdom of God" to take my next step or maybe pneumatology.
I think I've noticed strains of protological and eschatological within the church discourse, though generally not together. More left-leaning churches seem to tend toward eschatological and right more protological. I certainly think both are needed, plus a little more.
One of the things that I need to end up with is something that can distinguish "valid" work from "invalid" work. It's not enough to be able to say that secular work (or "sacred" work) CAN be good and part of the work of the Kingdom, but to be able to understand what it is that makes work valuable. I think Miroslav Volf and Darrell Cosden each offers interesting paths to explore. They are both a bit speculative, but interesting.
