Book much more interesting than the film, if you are pursuing analysis. By the way, the author, Baum, was a theosophist - a bogus 19th century “religion” created by drug users and homosexuals - Blavatsky et al. All of the Baum books in the Oz series (12) present theosophical doctrine within the stories - I love the books - grew up on them - but they’re the opposite of what I’d choose to apply to papal history.
I know. I’ve picked up original copies of his books and recently a penguin I want to read.
I know about his religious background. was trying fruitlessly to investigate the background of the screenwriter(s), who did much interpreting.
I wouldn’t apply specific Catholic theology, but basic virtues.
