Death Penalty for Mediums and Wizards
27“‘A man or a woman that is a medium or is a wizard shall surely be put to death. They shall be stoned with stones. Their blood shall be upon themselves.’”
Leviticus 20:27 prescribes the death penalty, by stoning, for any man or woman who practices mediumship or wizardry, declaring that such practitioners substitute counterfeit spiritual powers for covenant loyalty to God. The formula "their blood shall be upon themselves" signifies that the execution is just punishment and that guilt belongs entirely to the offender, not the community.
A medium or wizard dies not for mere superstition but for covenantal treason—choosing another lord over the God of Israel.
Catholic tradition reads this verse through the lens of the First Commandment and its defense in the Catechism of the Catholic Church (CCC 2110–2117). The CCC explicitly names "consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums" as violations of the virtue of religion, noting they "contradict the honor, respect, and loving fear that we owe to God alone" (CCC 2116). The Catechism draws a direct line from Leviticus to contemporary practice, showing this is not an obsolete scruple but a perennial spiritual danger.
St. Augustine, in De Divinatione Daemonum and The City of God (Book X), argues that demons mimic divine knowledge and exploit human curiosity to draw souls away from God. The medium or wizard, for Augustine, is not accessing neutral cosmic information but entering into a relationship with fallen angelic intelligences whose ultimate aim is the ruin of souls. St. Thomas Aquinas (Summa Theologiae II-II, q. 95–96) categorizes divination and magic as species of superstition, a vice against religion, because they implicitly or explicitly invoke demonic agency and usurp God's unique lordship over hidden knowledge.
The Church's Instruction on Prayers for Healing (Congregation for the Doctrine of the Faith, 2000) and successive papal addresses have reaffirmed this concern. Pope John Paul II in Tertio Millennio Adveniente called cultures of spiritism and occultism signs of a desperate search for transcendence gone astray. What Leviticus enforced with civil law, the New Covenant enforces through pastoral urgency: such practices constitute grave sin and rupture one's relationship with Christ.
The formula "their blood upon themselves" anticipates the moral theology of personal responsibility: culpability is proportionate to knowledge and freedom (CCC 1734–1736). Yet the Church also teaches pastoral compassion toward those drawn into occult practices through ignorance, manipulation, or cultural pressure.
The surface strangeness of a stoning law must not permit a comfortable distance from what this verse demands of contemporary Catholics. Occult practice—ouija boards, séances, tarot cards, mediums advertising on mainstream platforms, astrological guidance treated as spiritually normative—is not a marginal curiosity but a multi-billion-dollar industry deeply embedded in popular culture, including among practicing Catholics.
This verse calls Catholics to examine concretely: Where do I seek guidance about the future, about decisions, about the fate of those who have died? The Catholic answer is not silence but richness: Liturgy, Scripture, the Sacrament of Reconciliation, spiritual direction, prayer for the dead, the Communion of Saints. Christ has opened every legitimate door between heaven and earth; recourse to mediums is not an innocent supplement but a distrust of His sufficiency.
For Catholics who have engaged in occult practices—whether casually or seriously—this passage also invites the freedom of Confession, not paralysis of fear. The severity of the Levitical law is the shadow; the mercy of the Gospel is the light that makes the shadow intelligible. Take it seriously; bring it to the sacrament.
Commentary
Literal Sense and Narrative Context
Leviticus 20:27 stands as the final, climactic verse of a chapter that systematically enumerates offenses punishable by death or divine cutting-off. The chapter opened (20:1–5) with the prohibition of Molech worship and ends here with the prohibition of mediumship and wizardry—forming a literary bracket around offenses that constitute, at root, the same sin: the substitution of YHWH with a counterfeit spiritual power.
The Hebrew terms are 'ôb (medium, literally "a pit" or hollow vessel through which a familiar spirit speaks) and yidde'ônî (wizard or "knowing one," from yāda', "to know"). Both refer to practitioners who claim access to knowledge or contact with the dead and spirit-world outside of God's revelation. The pairing of "man or woman" (as also in Lev 19:31 and 1 Sam 28) is deliberate: this law applies without exception of sex or social standing. No one may lay claim to Israel's covenant while simultaneously consulting underworld powers.
The prescribed punishment—stoning—is the same penalty applied to blasphemy (Lev 24:16), Sabbath-breaking (Num 15:35), and adultery (Deut 22:24). In Israel's jurisprudence, stoning was a communal act; the whole assembly participated, underlining that this sin was not merely against an individual or family but against the entire covenant people. The community's holiness was endangered by the presence of such a practitioner.
"Their blood shall be upon themselves" is a forensic formula recurring throughout Leviticus 20 (vv. 9, 11–13, 16) and in Ezekiel's prophetic tradition. It is a declaration of legal and moral exculpation for the executioners and the community: the death is just; the guilt belongs entirely to the offender. It simultaneously implies that not executing the punishment would transfer culpability to the community, implicating Israel in the sin.
Typological and Spiritual Senses
On the allegorical level, the medium or wizard is a figure of anyone who seeks ultimate guidance, comfort, or power from a source other than God's self-revelation. The 'ôb opens herself as a vessel to a spirit that is not the Holy Spirit—an anti-Pentecost, a parody of prophecy. The Church Fathers read such passages as preparations for understanding that there is only one legitimate mediation: Christ (1 Tim 2:5). The one true "medium" between God and humanity is the Incarnate Word, who does not channel the dead but conquers death.
On the moral level, the radical severity of this verse teaches the gravity of the first commandment. The stakes of covenant fidelity are not trivial. The death penalty in Israel's theocratic economy communicates, in the currency of its age, that the soul who pursues occult allegiance is placing itself in mortal spiritual peril.
