I read this decades ago and found it very moving - despite the fact that I am not (and was not) very religious (to put it mildly). I only post it now because it came up recently in a conversation. I have no idea how it would read for me today, of course - and I have no plans to find out.
There is some discussion, as I recall, of Bernanos (and certainly plenty of discussion of his 'type') in Robert Wohl's important book, The Generation of 1914. Bernanos was a Catholic, but there are existential elements in his religiosity; a monarchist; and a supporter of Franco. But -- to his credit -- he eventually broke with fascism, thought little of Petain, and eventually moved somewhat to the Left -- i.e., to Gaullism.
Well..., you take what you can, I guess, in this dirty business of interwar history...
