I think Pope Augustine and the Great Monarch blended together in my mind, but you're right Samurai, they may be two different strains.
How does anyone here know that Pope Augustine is named "Gus," who here is on a first-name basis with this character? Has someone actually met the man?
Rescued by Mary reminded me of the guy who runs the romancatholicism.org website, due to the Jansenist theme. The difference is that he was against Jansenism rather than in favor of it. But if this is all an elaborate joke, that means nothing.
I just figured that somehow that site was involved with Augustine / Monarch, and that Augustine / Monarch were mocking the Angelic Pastor / Great Monarch prophecies. Maybe it's not. I don't know who is who, I just know there are lots of weirdos floating around.
Look at how Rescued by Mary started off with this elaborate, pseudo-scholarly essay and then, a day later, was spelling everything wrong and coming off like an amateur: "Er, who, what is traditionalism, what is Siri, what is a sede?" It came off as very phony.
I think there is someone or a group of someones out there who is playing various characters, like a chameleonic actor, just messing around with this site and with trads in general.
