I will say that I've learned something here -- I had never heard of the "Federal Vision" before I read this thread. Which I guess would suggest that, at least in my neck of the woods, it isn't really something adopted within our organization. It also means (since they apparently formally addressed this in 2007 in our general assembly), that I have not been paying attention to the recent goings-on of our assembly; I have thought I watched closely for signs of faltering in what I see as the major issues of gay marriage, gay and female pastors, and the like, but obviously not enough to see anything about the Federal View, which I now know a little about by reading wikipedia.
I did recognize a few of the names thrown about. I read some of Van Till and Rushdooney when I was younger, provided by my pastor, but I never figured out why I was reading it, and I'm not sure I ever really understood what they were getting at.
