Father Malachi was a retire RC priest and exorcist. My wife sent me a link to one of his radio interviews from 1996, there are several on YouTube. Being that each one is one to three hours long it’s going to take a while for me to get through them all. Finished #1 last night. He’s also authored dozens of books.
One thing he said near the end of the first interview made sense. A lot of people, even religious ones, no longer believe in the existence of hell. So to them there is no consequence for doing evil. I think he’s on target.
