Speaking of fallen angels, as I did last week, priests and bishops who don’t teach about the Devil and hell will probably end up there with them. The Enemy’s great coup is to assure dupes that he doesn’t exist, there is no hell, and that, “Even if hell exists, surely no one is there!”, blah blah blah.
The Devil and fallen angels are real, personal beings. There’s nothing cute about them. And they hate God, themselves, and you.
Fallen angels (demons) retain their angelic nature, though God restrains them so that they cannot wreak total havoc.
