... I have to pick my battles more carefully, and I am staying out of this one. But briefly, just like another German mystic, Hildegard von Bingen, Emmerich troubles me. It's not just guilt by association either, though they are both very popular with those who will most likely one day be deemed anti-Popes and other modernists.
I get a bad feeling just reading about them; not that this is proof of anything. But Hildegard comes off like a proto-feminist, and Emmerich, at times, like a proto-theosophist. However, because Brentano was the one who recorded so many of Emmerich's visions, people will always blame the bad aspects of them on him, and attribute all the good to Emmerich. Brentano is really the perfect alibi.
I think the devil used certain people to break open a door in the Church and that sometimes these people seemed very holy to their contemporaries. They were ahead of their time and complex in a way that was fascinating, but were their powers really from God?
Mind you, I used to think St. Joan of Arc was a witch and now she is one of my favorites. I am not drawing any conclusions, just expressing an uneasy feeling.
