Fr. Ripperger (I think) said that if you, without jurisdiction, speak the name of a devil, then that devil somehow receives power and glory. Father also mentioned that some of the characters in the Harry Potter books bear the actual names of real devils; and that children and adults--by reading the books that contain these characters' names--are unknowingly giving glory and power to devils. Granting that this is true (I don't want this to be a Harry Potter debate thread), this would seem to entail that the evil is effected by the mere act of reading or using the name, rather than by any intention on the reader's part. Is this correct?
But then what I am wondering is, how do we avoid doing this? Any unfamiliar word we come across might happen to be a devil's name. And even words that we are familiar with could just happen to coincide with the names of devils. Without learning the names of all the devils (which is probably a bad idea, not to mention humanly impossible), how are we to know which words to avoid?
Also, is the evil effected only by pronouncing the name vocally, or does reading the name silently in one's own mind have the same effect? (And what about just having the name printed on a piece of paper, without anyone ever reading it?)
This is a legitimately good question. Sadly, certain actors will come onto this, hijack it, and turn it into an smiffering yarn yielding no easy answers to your query. I remember last year, upon the desecration of the Vatican with that not to be named demoness from the jungle, a pastor at a local parish refused to utter the name but once for clarity, and then no more. I do not remember if there was an admonishment towards the laity not to say the malevolent banshee's name, but his onefer should be clue enough not to speak these names.
