Whether divination practiced by invoking the demons is unlawful?
Objections
❌ Objection 1 : It would seem that divination practiced by invoking the demons is not unlawful. Christ did nothing unlawful, according to 1 Pt. 2:22, "Who did no sin." Yet our Lord asked the demon: "What is thy name?" and the latter replied: "My name is Legion, for we are many" (Mk. 5:9). Therefore it seems lawful to question the demons about the occult.
❌ Objection 2 : Further, the souls of the saints do not encourage those who ask unlawfully. Yet Samuel appeared to Saul when the latter inquired of the woman that had a divining spirit, concerning the issue of the coming war (1 Kgs. 28:8, sqq.). Therefore the divination that consists in questioning demons is not unlawful.
❌ Objection 3 : Further, it seems lawful to seek the truth from one who knows, if it be useful to know it. But it is sometimes useful to know what is hidden from us, and can be known through the demons, as in the discovery of thefts. Therefore divination by questioning demons is not unlawful.
