No. The Ouija board is far from harmless, as it is a form of divination (seeking information from supernatural sources). The fact of the matter is, the Ouija board really does work, and the only “spirits” that will be contacted through it are evil ones.
It’s true that many people view the Ouija board as harmless. They often claim, “Oh, I don’t believe in it,” or something to this effect. However, a disbelief in something does not necessarily mean that something isn’t real. The Ouija board has an objective reality that exists apart from a person’s perception of it. In other words, it’s real even if you don’t believe in it. And we know this because God himself tells us so.
The Lord repeatedly condemns any and all occultic practices, including divination. While many Bible passages could be cited, the following one is typical of his view of occultic practices: “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” (Dt 18:10–12, NIV).
On the experiential side of the issue, we have the testimony of the Church’s exorcists. Their experience shows that Ouija boards are far from harmless. Some investigating supernatural phenomena from a Catholic perspective have gone so far as to say that 90 percent of their very worst cases involving demonic activity have been linked to the use of the Ouija board.
Simply put, nothing positive can ever come from the use of the Ouija board, and God warns us against such things for our own spiritual safety.
