I can only tell you that using or posessing a ouija board or any supernatural, magical, or occult item or method is always wrong regardless of intention.
I don’t personally believe your clothing would be possessed. How far would that line of thinking go? Would you move out of your home since it the evil was enacted there? Certainly not! Just destroy the board.
Using the computer for any evil purpose is wtong whether it is for occult, pornographic, or other reasons. The “evil”, though is in the sinner himself, not the machine. However, if the ownership of the computer should serve as a temptation to continue the illucit activities it would be best to sell or donate it after washing the drive.
The Ouija board was introduced as a board game, and was intended to be used as a way to contact the spirits of angels, demons or the dead. This is a dangerous practice. People have approached me about this and expressed their concern over my “hard-line stance on a board game.” This is precisely one of the big problems here: Disguising a fundamentally evil spiritual practice as a game for kids is, in my mind, the definition of evil.
Take a look at this passage:
[INDENT]Let no one be found among you who sacrifices his son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead. Anyone who does these things is detestable to the Lord. (Deuteronomy 18:10–12a)
The Scripture is clear, and many exorcists in the Catholic Church speak very strongly against the Ouija board. Whether we intend it for “fun” or not is irrelevant. It’s a loaded spiritual gun and we should destroy any of these things that are in our home.
-Fr. Joseph Krupp
Divination and magic
2115 God can reveal the future to his prophets or to other saints. Still, a sound Christian attitude consists in putting oneself confidently into the hands of Providence for whatever concerns the future, and **giving up all unhealthy curiosity **about it. Improvidence, however, can constitute a lack of responsibility.
2116 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.48 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.
2117 All practices of magic or sorcery, by which one attempts to tame occult powers, so as to place them at one’s service and have a supernatural power over others - even if this were for the sake of restoring their health - are **gravely contrary to the virtue of religion. **These practices are even more to be condemned when accompanied by the intention of harming someone, or when they have recourse to the intervention of demons. Wearing charms is also reprehensible. Spiritism often implies divination or magical practices; the Church for her part warns the faithful against it. Recourse to so-called traditional cures does not justify either the invocation of evil powers or the exploitation of another’s credulity.
