What Is a Medium? Meaning, History, and the Biblical View

What is a medium, exactly? Is it a gifted person who connects the living and the dead, a performer using old tricks, or something the Bible clearly mentions and condemns?

The answer depends a lot on your perspective—whether you’re in a séance, reading a legal case, or looking at Scripture. The history of the word is more unusual and better documented than most people think. Before we look at its meaning, origins, and what religions say about it, let’s start with a clear definition.

What Is a Medium?

A medium is someone who says they can communicate with the spirits of the dead, serving as a link between the living and what’s often called “the other side.” This is what sets a medium apart from a psychic.

Psychics claim to sense energy, intuition, or information about a living person’s past, present, or future. Mediums, on the other hand, specifically claim to contact spirits—usually deceased loved ones, but sometimes spirit guides, angels, or other non-physical beings.

Within this practice, sometimes called mediumship, channeling, or, in its older and more legally loaded form, necromancy, there are two broad categories recognized by practitioners and historians alike:

• Mental mediumship: The medium remains fully conscious and reports receiving messages from spirits through heightened senses. These are often called the “clairs”: clairvoyance (seeing images), clairaudience (hearing sounds or voices), clairsentience (feeling emotions), clairalience and clairgustance (smelling or tasting), and claircognizance (just knowing something).
• Physical mediumship: Less common and more dramatic. It involves things like rapping sounds, moving tables, objects appearing, or a spirit speaking through the medium’s voice while the medium is in a trance. Most of the fraud cases in mediumship history originate from this type, since it relies on effects people can see or hear.

Today, practitioners say that all mediums have some psychic ability, but not all psychics are mediums. In everyday language, the terms often overlap—many people call themselves “psychic mediums.” Still, the difference is important when examining specific claims, legal issues, or religious texts because “communicating with spirits” is understood as a distinct activity rather than a general intuition.

It’s important to be clear: no scientific study has ever proven that a medium can talk to the dead. This doesn’t mean every medium is lying—many truly believe in their experiences—but there is a big, well-documented gap between what mediumship claims and what has been proven, as the history below shows.

Medium vs. Psychic: Why the Distinction Matters

Since people often use these words as if they mean the same thing, it helps to explain the difference clearly:

• A psychic claims to perceive information about a living person — relationships, career, health, decisions — by tuning into that person’s energy, or by using tools like tarot cards, astrology, or palmistry.
• A medium claims to receive messages specifically from the deceased, with the stated purpose of providing comfort, closure, or proof that a loved one’s identity persists after death.

This difference is important for more than just marketing. Ancient legal and religious texts made the same distinction long before the word “psychic” existed.

Communicating with the dead was seen as a separate and more serious practice than fortune-telling. That’s why the Bible mentions it by name (as explained below) and why governments have often enacted special laws regarding mediumship.

The History of Mediums: From Ancient Necromancy to the Spiritualist Movement

Belief in communication with the dead is ancient. The oldest known documented reference to necromancy — the practice of consulting the spirits of the deceased — appears in a letter from the Old Assyrian trading colony of Kanesh, dated to roughly 1950–1850 BCE, describing the consultation of “spirits of the dead.”

Similar practices were documented among the Persians, Greeks, and Romans, and the Hebrew Bible repeatedly legislates against the practice among the ancient Israelites, evidence that it was a live, frequent temptation rather than a hypothetical one.

The modern, organized practice most people picture today — séances, rapping sounds, spirit messages relayed to a paying audience — traces to a specific, well-documented event. In 1848, two young sisters, Kate and Maggie Fox of Hydesville, New York, reported that they had made contact with a spirit that communicated through mysterious rapping sounds in their home. Their older sister, Leah, recognized the commercial potential and began managing public demonstrations.

On November 14, 1848, the sisters gave the first paid public demonstration of their abilities at Corinthian Hall in Rochester — an event widely credited as the formal beginning of the Spiritualist movement, the religious and cultural belief that the spirits of the dead can and do communicate with the living, and that the dead continue to grow and develop in the afterlife.

Spiritualism became very popular in the late 1800s in the United States and Europe. This happened just four years after Samuel Morse sent the first telegraph message, and people at the time compared séances to a “spiritual telegraph” connecting two worlds. For some, mediumship was a serious spiritual practice. For others, it became a profitable show, with dramatic lighting, music, and table-tipping tricks.

The movement lost much of its credibility in 1888 when Margaretta (Maggie) Fox admitted to the press that the rapping sounds were made by cracking her feet and toes. She even showed how she did it. About a year later, she recanted her confession, and historians still debate why. Still, many investigations during the Spiritualist era found similar tricks used by other professional mediums.

By the early 1900s, investigations became even more serious. In 1922, Scientific American magazine, with help from Sir Arthur Conan Doyle (the author of Sherlock Holmes and a Spiritualist), set up a panel of scientists and investigators. They offered a $2,500 prize to any medium who could show real psychic abilities under controlled conditions.

Magician Harry Houdini joined the committee because his experience with stage tricks helped him notice things scientists might miss. The most debated case was with a Boston medium, Mina “Margery” Crandon, who almost won the prize. After seeing one of her séances, Houdini decided it was “all fraud.”

Houdini later wrote a book titled A Magician Among the Spirits (1924), in which he described many tricks used by mediums. He also traveled around the country, offering $10,000 to any medium who could do something he couldn’t copy with stage magic. No one ever won the prize.

Mediumship also collided directly with the law. In England, the Witchcraft Act of 1735 had already criminalized claiming magical powers; in 1944, it was revived to prosecute Helen Duncan, a Scottish medium convicted on charges connected to fraudulent séances and sentenced to nine months in prison — she is generally regarded as the last person convicted under that 1735 statute, alongside Jane Rebecca Yorke, convicted the same year for falsely claiming to summon the spirits of the dead.

The outdated law was replaced in 1951 by the Fraudulent Mediums Act, which made it a specific offense to act as a medium “with intent to deceive” for financial reward, while explicitly exempting mediumship performed purely for entertainment.

That law was repealed in 2008 and folded into general consumer-protection regulations, meaning fraudulent mediumship in the UK is now prosecuted the same way as other deceptive commercial practices rather than as a named offense.

Despite repeated instances of fraud, the Spiritualist movement continued and formed lasting organizations. Spiritualist churches, like those in the National Spiritualist Association of Churches in the United States, still hold regular services. These often end with a formal “demonstration of mediumship.”

What Does the Bible Say About Mediums?

The Bible talks about mediums directly and often, using clear legal language. Its message is clear: consulting a medium is forbidden.

The Hebrew text uses two specific, paired terms for this practice: ob (sometimes transliterated ’ôb) and yidde’oni. According to ancient Jewish tradition recorded in the Talmud, the ob practitioner was understood to make a spirit’s voice seem to appear from the joints or armpits — essentially a form of ventriloquism — while the yidde’oni spoke through the mouth, sometimes using the bone of an animal as a prop.

The ancient Greek Septuagint translation actually renders the Hebrew term as engastrimuthos, literally “one who speaks from the belly” — a ventriloquist — reflecting how the practice was understood by ancient interpreters nearly two thousand years before modern stage mediums were accused of using similar vocal tricks. The medium Saul consulted at Endor is called in Hebrew a ba’alat ob, roughly “mistress of the ob” or “possessor of a spirit.”

The legal prohibitions appear across the Torah. Leviticus 19:31 instructs the Israelites not to turn to mediums or spiritists, warning that doing so brings defilement. Leviticus 20:6 goes further, stating that God would turn against anyone who sought out mediums and would cut that person off from the community. Leviticus 20:27 prescribes death by stoning for anyone who practiced as a medium among the Israelites.

Deuteronomy 18:10–12 groups mediums together with diviners, sorcerers, and those who “call up the dead,” describing these practices as detestable and citing them as one of the reasons the pagan nations occupying Canaan were driven out.

Later, in Isaiah 8:19, the prophet poses the issue as a pointed rhetorical question: why would a people consult the dead on behalf of the living, when they could consult God directly? Isaiah elsewhere (8:19, 29:4) describes the necromancer’s speech as a “whisper” and a “mutter,” language ancient commentators connected to the ventriloquist-style technique described above.

The most detailed narrative example is the story of King Saul and the medium at Endor, recorded in 1 Samuel 28. Saul had previously banned mediums and spiritists from Israel, in keeping with the law he himself was bound by. But facing a Philistine invasion and unable to get an answer from God through prayer, dreams, or prophets, Saul disguised himself. He traveled at night to consult a medium, asking her to summon the spirit of the prophet Samuel, who had already died.

According to the account, a figure identified as Samuel appeared — described only as “an old man… wrapped in a robe,” visible to the medium but apparently heard only as a voice by Saul — and delivered a grim prophecy: Saul and his sons would die the next day in battle against the Philistines.

The prophecy came true at the battle of Mount Gilboa. First Chronicles 10:13 later sums up the episode in blunt terms, explicitly listing Saul’s consultation of a medium, alongside his broader unfaithfulness, as the reason God turned the kingdom over to David.

Bible scholars and commentators differ on the precise mechanics of what happened at Endor — whether the spirit that appeared was genuinely Samuel through a unique act of God’s own intervention, a demonic impersonation exploiting the medium’s ritual, or some other explanation entirely — but they broadly agree on where the moral weight of the passage falls: Saul’s failure was disobedience and desperation that drove him to seek answers outside of God’s appointed means, not a referendum on whether the medium’s particular powers were genuine.

The New Testament doesn’t use the word “medium” directly, but it represents the same caution in different terms. First John 4:1 instructs believers to test every spirit rather than believe it, warning that many false prophets have gone out into the world. Revelation 21:8 lists those who practice “magic arts” among those facing judgment.

Acts 16:16–18 records the apostle Paul encountering a slave girl who was said to have a “spirit of divination” and to accurately predict events. Paul’s response was not to debate whether her ability was genuine but to cast the spirit out as something to be opposed rather than consulted.

Overall, from Leviticus to Revelation, the Bible treats seeking guidance from spirits rather than from God as spiritually dangerous. In the Old Testament, it was even a capital offense, no matter if the spirit was real, fake, or something else.

Are Mediums Real?

Apart from religious concerns, mediumship has been closely examined by scientists and skeptics for over 150 years, as shown in the Scientific American investigation and Houdini’s efforts.

Investigators often found things like hidden helpers, secret devices, joint-cracking sounds mistaken for spirit noises, and cold reading—where a medium makes broad statements that people fill in with their own details. These findings explain many of mediumship’s apparent successes without needing any paranormal explanation.

Some early researchers split into two camps over how to interpret cases that weren’t simple fraud: Spiritualists maintained that genuine mediums channeled actual discarnate spirits, while early parapsychologists, including Joseph Banks Rhine, argued that any unexplained phenomena were more likely the product of the medium’s own unconscious psychic ability (such as telepathy) rather than communication with the dead — a split that, by the early twentieth century, led the two camps to formally separate their fields of study.

Neither side has produced evidence that meets strict scientific standards, and no medium has ever passed a carefully controlled test for real spirit communication. After more than 175 years of research, the conclusion is the same: claims of spirit communication are still unproven, and fraud—intentional or not—has been a common part of mediumship since it began.

Common Misconceptions About Mediums

It’s helpful to clear up a few points, since popular culture often mixes these ideas together:

• A medium is not the same as a witch, sorcerer, or wizard, although biblical law groups all of these activities under the same prohibition. In modern usage, mediumship is framed as a claimed inherent ability to perceive spirits, rather than a learned practice of casting spells.
• Mediums generally do not claim to predict the future. Unlike psychics, who are often sought out for guidance on decisions, mediums typically frame their work around connecting with the deceased for comfort and closure rather than forecasting.
• “Psychic medium” is a blended, informal title, not a distinct third category — it simply signals that the person offers both general psychic readings and mediumship in the same session.
• A trance medium is not the same as a mental medium. A trance medium claims to enter an altered state of consciousness and allow a spirit to speak directly through their body and voice, while a mental medium remains fully aware and reports impressions rather than being “taken over.”

The Bottom Line

Simply put, a medium is someone who claims to talk to the spirits of the dead. This practice goes back almost four thousand years to early necromancy, took its modern form with the Fox sisters in 1848, and still exists today—even though there is a long history of fraud, from Houdini’s investigations to British court cases.

For those looking at this topic from a biblical perspective, the answer is very clear: Scripture does not focus on whether the power is real, but says that consulting mediums is forbidden instead of seeking God. This warning appears in legal language from Leviticus to Isaiah. It is shown in the story of King Saul’s last night before Mount Gilboa.
