I have long been intrigued (and mystified!) by the Old Catholics. I have been aware for many years of an affinity between some Eastern Orthodox and the Society of Friends, but this is my first "screen-to-screen" encounter with an Old Catholic!
I was once a graduate teaching assistant to the Orthodox priest who served the Lansing MI area. He was also a sociologist, and I assisted him with the Sociology of Religion course at Michigan State University.
He advanced to me a model of the affective dynamics of a Friends' meeting for worship. At the time, I didn't put much stock in what he said, but now I think he hit the nail on the head rather accurately.
In any case, welcome once again to QQ. I look forward to your input into the dialogue here!
By the way, is there a significant Old Catholic community in New Zealand? And what does "TSSF" stand for?
