Thanks to you and all for the discussions.
“A school of thought may be called “gone from the world of Christianity,” but a school of people with Christians in it, may not be.”
I’m not sure what you are getting at. Certainly there are still some believing Christians who attend Episcopal churches. That makes the believers Christian. Not the Episcopal church. But then, “the Church” is the believers. So while formal organizations may come and go from Christianity, the Church will last until the end.
I grew up Episcopalian. My parents were saved as Episcopalians during the charismatic revival in Colorado in the 70’s. But today, I see no reason to honor the formal organization with the title “Christian”, when it has done it’s utmost to leave the world of Christianity—in my opinion, successfully.
On matters not subject to disputation, Jesus and the Apostles drew pretty clear lines. The Episcopalians stepped over a pretty clear line. OTOH, I’m not going to get into it with Presbyterians over predestination. But then, the Bible does not expressly forbid belief in predestination.
