Are you against the Catholic Church’s work against the devil?
One potential problem here is that people who are not qualified exorcists, and a large sub-set of that is people who are not validly ordained priests, will pick up these books and attempt to do things beyond their understanding and their competence.
Demons don’t play games. Neither do they allow beginners an opportunity to learn as they go along; the way that when someone is learning a new sport, the experienced players might say “go ahead and throw that again, we’ll let you do it over because you’re new.” No, demons are not like that.
Access to rituals like this have been restricted for very good reason.
I am concerned, yes truly, that people who do not know anything about exorcisms might easily acquire these books and attempt sort of do-it-yourself exorcisms. That’s a recipe for disaster.
The good news is that the texts of the major exorcisms are being restricted as to who can purchase them. I just wonder how long that might last in this digital age–not long, I presume.
As far as the English language itself goes, or for that matter any other vernacular, these texts have already been available to priests for decades now. It is only the updated rituals that have not been translated until recently.
