I’m not Catholic therefore can’t comment on the basic beliefs but Fr. Martens says some really interesting things concerning the various demonic forms and also about trauma and illness. Trauma is bigger than even I thought but have come to realize how enormous it truly is in my job. Illness is considered a trauma. The occult is also at the top of the danger list. I urge you to watch to the end, even if you disagree with the dogma.
I frequented the Co-Cathedral for the organ recitals and other music events. Wish I’d known about this, as I’m sure there’s more to it than the hour-long video.
