The below linked article is everything that is wrong with the Catholic Church’s approach to possession.
- If you recite a lengthy prayer in order to provoke the daemon into response, then you may be doing little more than indulging the fantasy of a person in need of psychological help. If the fantasist is merely seeking attention, then you may purely feed the need.
- A more valid approach to testing possession would be the recitation of a mundane phrase, although in an language unknown to the person (Aramaic, Latin etc.).
The list of activities best avoided in order to avoid possession reads:
From CCC paragraph 2116: “Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.”
-well, that is me damned and possessed then. Such would explain a great deal. At least I know the name of my daemon and work with it. Such release from notions of fear empowers me.
