One time, I had a practicing Episcopal priest tell me he wasn’t sure if there was a God — true story. Mainline Episcopal priests are simply liberal social workers, nothing more.
Maybe that's why he still had to practice: one is not ready for the big time until one can get it right.
Wasn't Joseph Fletcher, author of Situation Ethics where so much of the religiously-liberal heresy got codified, himself an Episcopal priest who decided there wasn't a God?
