I spoke with a young man who was battling authentic demonic oppression for over twenty years after being in a room where a Ouija Board was being used when this young man was in seventh grade.
He shared that he felt something come into him and that from that point on in his life, he knew he was battling a Demon that had considerable ability to harm him (head aches and weariness) and to suggest things to him denigrating himself, his family, discouraging him from going to Church, discouraging him from confession and priests, and much more.
Stay away from fortune telling, Ouija boards, Tarot Cards, and all that other garbage. EVIL IS REAL.
“All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to ‘unveil’ the future. 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”
- Catechism 2116
Note that Deuteronomy compares all these evil consultations with killing children: “Let there not be found among you anyone who immolates his son or daughter in the fire, nor a fortuneteller, soothsayer, charmer, diviner, or caster of spells, nor one who consults ghosts and spirits or seeks oracles from the dead."
- Deuteronomy 18: 10-11
St. Paul and Deuteronomy note that those who engage in these types of acts commit mortal sins. It is SUPER SERIOUS
As noted from this particular young man's story, even those AROUND this type of activity can be harmed in serious ways.
