Better churches than the ones we have (as a whole) is a slippery, subjective, and potientially insulting prospect. But it still rates better than not clearly prjecting what each of us thinks would be desirable. We do not live in the best of all possible worlds.
I was thinking that rather than describing theologically (or primarily so) how we would want the UUA, perhaps it would be better to suggest how a particular hypothetical congregation would run. What would be central. How would it make decisions. The nuts and bolts stuff that follows — if done well — the metanarrative work. The machine that suggests the spirit.
Perhaps we could write some guides or fragments of guide about what would make an ideal congregation, and make them public, perhaps under the Creative Commons Attribution (or Attribution-No Commercial Use) licence, so that others can build upon them and share them.
And perhaps actually use them to help start or improve congregations.
