Quite long so i cant read right now.
So does this mean Catholics who have ever read books, comics, watched movies with 'magic' in them have committed a sin?
What does magic mean here? Again i have not read the full article or any others.
"Magic" as an illusion is a form entertainment. Not a sin per se.
As far as I know, real magic is the practice of occult rituals, and it usually conjures demons and ask for their help, be it for a good or evil purpose. This is always a sin.
