Spiritualism and Deuteronomy 18: What God Forbids
Short answer: Deuteronomy 18:9-14 forbids God's people from imitating the abominations of the nations, including consulting mediums, wizards, and the dead. The passage lists these practices among things Yahweh calls abominable, and it grounds the command in Israel's calling to be blameless before him. Spiritualism is therefore not a neutral curiosity or a harmless cultural practice; Scripture treats it as rebellion against the living God. The same prohibition appears in Leviticus 19:31 and Leviticus 20:6, and Isaiah 8:19-20 exposes the absurdity of consulting the dead on behalf of the living. The New Testament continues this posture when it lists sorcery among the deeds of the flesh in Galatians 5:19-21.
What Deuteronomy 18:9-14 Actually Says
The passage opens with a command that is both gracious and serious: when Israel comes into the land Yahweh gives them, they must not learn to imitate the abominations of those nations. The land is a gift, not a prize. The warning is not merely against private occult curiosity but against adopting the religious culture of Canaan. The verb learn matters. These practices could be studied, imitated, and absorbed into daily life until they seemed normal. God tells his people to refuse that path from the beginning, before familiarity softens their resistance.
The verses that follow describe the specific practices: divination, soothsaying, interpreting omens, sorcery, charming, consulting mediums and wizards, and inquiring of the dead. The list is not exhaustive of every possible occult technique, but it names the main categories that pervaded Canaanite religion. Each practice tries to gain knowledge, power, or guidance apart from Yahweh. The issue is not merely technique but trust: who is the source of truth and direction for your life? The living God, or the dead and the demonic?
The text calls all of this an abomination to Yahweh. That word is strong and is used elsewhere for idolatry and sexual perversion. It does not describe a minor weakness or a cultural quirk. It describes something God detests. This is why Deuteronomy 18 is not just about ancient Canaan; it reveals God's settled posture toward every attempt to approach spiritual power on terms other than his own. The command is not grounded in superstition about magic but in the holiness and exclusivity of Yahweh.
Verse 13 gives the positive counterpart: Israel is to be blameless before Yahweh their God. The nations are driven out because of these abominations, and Israel is warned not to repeat them. The call to be blameless does not mean sinless perfection in every area; it means wholehearted loyalty to God rather than divided allegiance with the occult. The contrast is between a people who listen to Yahweh and a people who consult mediums and the dead. The passage ends by repeating that these nations were dispossessed because of these very practices, making the warning concrete and urgent.
Why Mediums and Wizards Are Not Neutral Helpers
Leviticus 19:31 says, "Don't turn to those who are mediums, nor to the wizards. Don't seek them out, to be defiled by them. I am Yahweh your God." The command treats the act of seeking them out as defiling. Defilement is not just a feeling of guilt; it is a real change in one's standing and fellowship before God. The verse ends with the reminder, I am Yahweh your God. The prohibition is tied to the covenant relationship. To seek a medium is to seek another spiritual authority besides Yahweh, and that is a form of unfaithfulness.
Leviticus 20:6 intensifies the warning: "The person that turns to those who are mediums and wizards, to play the prostitute after them, I will even set my face against that person, and will cut him off from among his people." The language of prostitution is deliberate. It describes spiritual adultery. The issue is not simply that mediums give bad advice; it is that turning to them is a betrayal of covenant loyalty. God says he will set his face against such a person. That is a frightening statement. To have Yahweh set his face against you is far worse than any harm a medium could do.
These two passages show that spiritualism is not a side issue in Scripture. It is a direct rival to trust in God. The medium claims to offer access to hidden knowledge, departed loved ones, or spiritual power. But the Bible insists that God alone is the source of wisdom and life. The medium cannot deliver what only God can give. Instead of helping, the practice defiles and cuts off. The language is severe because the danger is severe, and because God's jealousy for his people is not petty but protective.
Some people today insist that they consult mediums only for comfort or curiosity, not for worship. But the Bible does not divide spiritualism into harmless and harmful categories. The act itself is treated as turning away from God. That does not mean every person who has ever dabbled in the occult is beyond hope; Scripture is full of people who repented of serious sin, including sorcery. But it does mean the practice cannot be baptised as a neutral hobby. It belongs to the realm of the flesh, not the Spirit.
Isaiah 8:19-20 and the Absurdity of Consulting the Dead
Isaiah 8:19-20 says, "He will be a sanctuary, but for both houses of Israel, he will be a stumbling stone and a rock that makes them fall. For the people of Jerusalem, he will be a trap and a snare.t with their God? Should they consult the dead on behalf of the living?" The prophet's logic is devastating. Why would the living abandon the living God to interrogate the dead? The dead know nothing and can do nothing for the living unless God permits it. The chirping and muttering of mediums is a parody of true revelation. It sounds like speech but carries no authority from Yahweh.
The question, shouldn't a people consult with their God, is not rhetorical in a cynical way. It is a call to sanity. Israel had the law, the prophets, and the covenant. They had no need to chase after whispers from the grave. The nations around them consulted the dead because they did not know the living God. But Israel did know him. To turn to mediums was to act as if they did not. Isaiah's contrast is between the clear word of God and the murky mutterings of the occult.
Verse 20 adds, to the law and to the testimony! If they do not speak according to this word, surely there is no morning for them. The standard is not personal experience or spiritual sensation but the written word of God. Any spiritual claim that contradicts Scripture has no light in it. Isaiah uses the image of morning light to describe hope and truth. Where the law and the testimony are rejected, there is no dawn. The occult offers a counterfeit light, a glow that leads further into darkness rather than out of it.
This is why Christians must test every spiritual experience against Scripture. A medium may speak accurately in some details, as the slave girl in Acts did until Paul silenced her. But accuracy is not the test. The test is whether a practice honours God and agrees with his word. If it does not, it must be rejected, no matter how impressive or comforting it seems. The living God is not honoured when his people go to the dead for answers.
The Whole Bible's Consistent Witness
Spiritualism is not condemned in one isolated law and then quietly tolerated elsewhere. The whole Bible maintains a consistent witness. Deuteronomy 18 forbids it. Leviticus 19 and 20 reinforce it with covenant language. Isaiah 8 mocks its absurdity. Galatians 5:19-21 lists sorcery among the deeds of the flesh, alongside adultery, sexual immorality, and uncleanness. The New Testament does not treat the occult as a harmless leftover from an ancient superstition. It treats it as a work of the flesh that excludes people from the kingdom of God if they persist in it without repentance.
Galatians 5:19-21 says, "Now the deeds of the flesh are obvious, which are: adultery, sexual immorality, uncleanness, lustfulness," and the list continues with idolatry and sorcery. The point is that these things belong to the old life, not the new creation. The Spirit and the flesh are opposed to each other. If a person claims to belong to Christ but continues to practice sorcery or consult mediums, there is a fundamental contradiction. The fruit of the Spirit is love, joy, peace, patience, and self-control, not fascination with hidden powers.
This consistency matters because some people try to argue that the Old Testament laws about mediums were only for ancient Israel and do not apply to Christians. But the New Testament's inclusion of sorcery in the works of the flesh shows that the underlying moral principle remains. God has not changed his view of attempts to contact the dead or manipulate spiritual power. The forms may change, but the fundamental rebellion is the same. Christians are called to resist it, not redefine it as harmless.
The Bible also consistently shows the real danger. King Saul, after banning mediums from Israel, consulted one at Endor when God stopped answering him. The woman produced an apparition, and Saul heard his doom. He died the next day. The story in 1 Samuel 28 is a vivid warning that dabbling in the occult does not lead to blessing or control. It leads to judgment and despair. The Bible does not tell this story to entertain us but to warn us.
Spiritualism and the Christian Today
Spiritualism in the modern sense includes séances, mediumship, channeling, tarot cards, Ouija boards, astrology, Reiki, and various forms of divination. It also includes softer practices such as consulting psychics for life guidance or trying to contact deceased loved ones through a medium. The forms vary, but the question remains the same: are you seeking guidance and comfort from a source other than God? The Bible's answer is clear. Do not learn the way of the nations. Do not consult the dead on behalf of the living.
Some Christians wonder whether reading a horoscope or playing with a Ouija board as a joke is really a problem. But the Bible does not treat these things as jokes. They are doorways into a spiritual realm that is not neutral. They can also be genuine means of spiritual deception. The fact that a practice seems silly does not make it safe. Israel was warned not to imitate the abominations of the nations, and those warnings were not about avoiding bad manners. They were about avoiding real spiritual harm and real offence against God.
At the same time, we must be careful not to become superstitious about the occult, as if it were a rival power equal to God. The Bible never presents mediums as having ultimate power. They are portrayed as weak, deceptive, and subject to God's authority. When God permits them to speak, he is still sovereign. The point is not to fear them but to refuse them. Christians do not need to live in dread of curses or spells. We belong to the one who has all authority in heaven and on earth. But we must not play with what God has forbidden.
For those who have already been involved in spiritualism, the gospel offers real hope. The Ephesian believers burned their occult books and turned to Christ. Sin can be forgiven, and the power of darkness can be broken. Repentance means turning away from the practice, not merely feeling bad about it. It means renouncing the medium, the spell, and the horoscope, and turning to Jesus. He is the one who has conquered the powers of darkness and offers life to all who come to him.
How This Affects Grief and Loved Ones
Much spiritualism today is driven by grief. People miss their dead loved ones and long for one more conversation. That longing is human and understandable. The Bible does not mock it. But it does warn against satisfying it in forbidden ways. The dead cannot be summoned at will, and the living are not to seek them. Instead, Scripture directs the grieving to the God of all comfort, who is near to the brokenhearted. He is the one who promises resurrection and eternal life, not through a medium but through Jesus Christ.
The contrast is sharp. The medium offers a vague presence, a cold reading, or a voice that may deceive. The gospel offers a sure hope: Christ has been raised from the dead, and those who are in him will be raised also. First Thessalonians tells believers not to grieve as those who have no hope, because Jesus died and rose again, and God will bring with him those who have fallen asleep. That hope is not based on a séance but on the empty tomb. It is not accessed by a medium but by faith.
Christians should also be gentle with those who have been deceived. Many people who visit mediums are not rebelling against God deliberately. They are hurting and looking for help. The right response is not contempt but compassion, combined with a clear warning. We can acknowledge the pain without approving the practice. We can point to Jesus, who wept at a tomb and then called Lazarus out. He is the resurrection and the life. That is better news than any medium can offer.
Finally, the church must be a place where grieving people can find real comfort. If we offer only platitudes and shallow answers, we should not be surprised when people look elsewhere. The body of Christ should be a community where the bereaved are supported, prayed for, and reminded of the resurrection. That does not replace the command to avoid mediums; it fulfils the positive calling to be blameless before God and to love our neighbour as ourselves.
Spiritual Power Belongs to God Alone
Deuteronomy 18 is not merely a list of forbidden activities. It is a declaration that spiritual power and spiritual knowledge belong to Yahweh alone. The nations around Israel sought power through divination and the dead because they did not know the living God. Israel was called to be different. They were to trust God's word, obey God's commands, and seek God's face. The same calling applies to the church. We are not to imitate the world's spiritual techniques. We are to be blameless before God, trusting him for guidance and comfort.
This does not mean Christians should be anti-supernatural. We believe in angels, demons, miracles, and the resurrection. But we believe these realities are under God's sovereign rule. We do not manipulate them through rituals or techniques. We pray, we read Scripture, we seek the Spirit's leading. The difference between magic and prayer is not just technique; it is relationship. Magic tries to control spiritual forces. Prayer submits to the living God. The medium seeks power. The believer seeks the Lord.
That distinction has practical implications. When we face uncertainty, we should go to God's word and prayer, not to a psychic or a horoscope. When we face grief, we should go to the God of all comfort, not to a séance. When we face fear, we should remember that Christ has conquered the powers of darkness, not try to appease them. The Lord's Supper, baptism, and the gathered worship of the church are the ordinary means God uses to strengthen his people, not secret rituals or hidden knowledge.
In the end, Deuteronomy 18 calls God's people to be blameless. That word can sound intimidating, but it is a call to wholehearted trust. We are not to be people who run after every spiritual novelty or every medium who claims to have a message. We are to be people whose confidence is in Yahweh, who has spoken in Scripture and ultimately in his Son. That is a secure place to stand, and it is far better than the muttering of the dead.
Biblical fidelity check
Deuteronomy 18:9-14 establishes that God's people must not imitate the occult practices of surrounding nations, including consulting mediums and the dead. It does not establish that every reported spiritual experience is demonic, nor does it give a detailed procedure for diagnosing every case. It also does not promise that refusing the occult will make life easy or that all questions will be answered. The passage is a boundary, not a comprehensive manual. It tells us what God forbids and why: these things are abominations and incompatible with covenant loyalty.
A common misreading is to treat the passage as merely cultural and time-bound, as if ancient Canaanite religion were a unique threat that no longer exists. But the New Testament lists sorcery among the works of the flesh in Galatians 5:19-21, and the underlying issue, seeking spiritual power apart from God, never goes away. Another misreading is to become obsessed with the occult, seeing demons everywhere and living in fear. That is not biblical either. The Bible calls us to reject these practices with clear-eyed trust in God's sovereignty, not to fear them as equals to God.
Other passages that speak to Deuteronomy 18:9-14
Several connected passages help us understand this theme. 1 Samuel 1: Hannah's Prayer and Samuel's Birth introduces the prophet whose ministry would later confront Saul's consultation with a medium. 1 Samuel 10: Samuel Anoints Saul and Signs Confirm shows Saul's early anointing and the Spirit's empowerment, a stark contrast to his later rebellion. 1 Samuel 11: Saul Rescues Jabesh Gilead and Renews Kingdom displays Saul's early obedience and military success. 1 Samuel 12: Samuel's Farewell and Israel's Demand for a King records Samuel's warning that obedience to God matters more than any outward success, a warning Saul would later ignore when he turned to a medium.
Frequently asked questions
Is consulting a medium always a sin, even if the medium seems kind and helpful?
Scripture treats the act of consulting mediums as forbidden regardless of the medium's character or apparent helpfulness. Leviticus 19:31 says not to turn to mediums or seek them out, and the reason given is covenant loyalty to Yahweh. The issue is not whether the person is nice but whether the practice honours God. A kind medium is still a medium. The Bible does not evaluate the practice by results or personality but by God's command. That does not mean we should be harsh with people who are deceived; we should be compassionate and clear.
Can Christians watch movies or read books that feature spiritualism?
Christians differ on how to apply this in the area of entertainment. The Bible does not directly address film or fiction. What matters is whether the material leads you to fear, entertain, or experiment with forbidden practices, or whether it helps you understand and reject them. Some believers can watch a documentary about the occult without spiritual harm; others find it a temptation. Romans 14 principles apply. Do not violate your conscience, and do not cause a weaker brother to stumble. The key is that your engagement does not become an endorsement or an open door.
What should I do if I have already been involved in spiritualism?
Turn to Christ in repentance and faith. The Ephesian believers who practiced magic arts publicly burned their books and turned to the Lord. Sin can be forgiven, and the power of darkness can be broken. Renounce the practice, destroy any occult objects, and seek help from a mature Christian or pastor. Do not be paralysed by fear of curses or retaliation. Christ has conquered the powers of darkness, and those who are in him need not be afraid. Confess, receive forgiveness, and walk in the freedom he gives.
