All if you want to see what they are really all about, and up to..check out the Center for Progressive Christianity
Thanks right back. I looked up Rigas and his ilk upon my return from DC -- and sent lots of pertinent info to selected members of our choir. We were visiting the Cathedral where we had been invited to sing before the main 11:00 service. Apart from the music (self-congratulatory wink!) and the majesty of the setting, I could have done without the trip.
