Do you remember the Episcopal ghost in The Great Divorce? It's uncanny, isn't it? I myself am Episcopalian, and Lewis' portrayal makes me laugh and cringe every time.
In response to Mr. Above-All-That-Superstitious Nonsense, here is a quote from Mrs. Brady via Standing on My Head (the link won't work now, but I'll fix it):
“People who want a religion without the supernatural don’t want a religion, they want a set of table manners.”
And table manners are overrated.
