I have heard the argument about the plague leading to a decrease in priest and nuns and the need to ordain/install more. Logically that makes sense, but I haven’t take the time to really drill into it.
I have never heard of the Luder/Luther/Beast comment. That sounds a bit specious. People love to come up with ways to prove that the Pope is the AC/beast and I generally discount any attempts to ‘prove’ that someone is the beast. Only the end of days will show us and we probably won’t even figure that one out until the big guy comes home.
I suppose there is some truth to this mixed in with a lot of lies/distortions. If it smells like propaganda, it is probably propaganda. As followers of Christ I think we need to steer clear of this kind of writing and focus on today and bringing our separated brothers and sisters in Christ back home.
