My dad used to come home from session* meetings and loudly complain that other people on the session or in the church "might be Christians, but they weren't Presbyterians." What he meant was that loving Jesus was one thing, but understanding the Presbyterian polity, the balance of power between the session and the minister and the role of the Presbytery was what being a Presbyterian was really about and to be a real Presbyterian you had to understand those distinctions. And yes, it takes a lot of real Presbyterians to run an effective church.
I would never call UUs who don't understand UU polity "not UUs", if only because my voice would give out before I got through saying that to half the people I've met who deserve to hear it.
But maybe we need to get back into teaching some of that stuff. The amount of ignorance about it is embarassing.
who freely admits that Steve Caldwell can kick her ass on the minor details, but has a good idea of the basics and wishes most other UUs had a Chalicechick if not a Caldwell level of understanding.
*the Presby equivalent of the board. Yeah, you probably knew that.
