I think the show did a real service by showing how corrupt and hopeless the currrent Episcopal Church really is. The writers probably didn't intend it that way, but that's what happened.
I spent a couple hours with a bunch of people from my old Episcopal church the other day. It was sad because I like them and I miss them. But I know how twisted and perverse the church and my parish are. There is no going back. I was warned it was better to make a clean break, and I see why, but I work with a couple of people from there and it isn't quite that cut and dried.
OTOH, I had a chance to talk about Catholicism with a fellow who is very theologically sound and who is doing his dissertation on Lewis' writings. He was open to the Church. I wish I had had a chance to bring up G.K. Chesterton with him, as he told me a story of having dinner with Lewis' secretary and finding he had converted to Catholicism because that is where the core of Christianity is now located. And where it must be defended, IMO. That's why I'm there. A defender of the Faith. That's what I am.
