Grimoires & the Church: Why Monks Copied Magic Books
Share
BY NICOLE LAU
Here's the paradox: the Catholic Church condemned magic as heresy, demonic, and punishable by death. Practicing magic could get you tortured, excommunicated, or burned at the stake. Owning a grimoire was evidence of witchcraft.
And yet, many of the grimoires that survived to the modern era were copied in monasteriesβby the very monks who were supposed to condemn them.
The Key of Solomon, the Sworn Book of Honorius, the Picatrix, and countless other magical texts were preserved in monastic libraries, copied by clerical scribes, and hidden among theological manuscripts. Some of the most important grimoire manuscripts are in the Vatican Library, the British Library (from dissolved monasteries), and other ecclesiastical collections.
Why? Why would monksβmen who had taken vows of obedience to the Churchβcopy texts that the Church condemned as satanic?
The answer reveals a complex, contradictory relationship between the Church and magic. It's a story of intellectual curiosity, theological justification, secret networks, and the thin line between prayer and spell, between angel and demon, between saint and sorcerer.
What you'll learn: The Church's official condemnation of magic (councils, papal bulls, Inquisition), which grimoires were banned and why, the paradox of monastic copying (why monks preserved forbidden texts), theological justifications for "natural magic" vs. "demonic sorcery," the role of the Inquisition in grimoire trials, where surviving grimoire manuscripts are today, and how the Church both destroyed and preserved magical knowledge.

The Church's Official Position: Magic is Heresy
Early Church Condemnations
The Bible: The Old Testament condemns magic and divination: "You shall not permit a sorceress to live" (Exodus 22:18). "Do not turn to mediums or necromancers" (Leviticus 19:31). "There shall not be found among you anyone who practices divination or tells fortunes or interprets omens, or a sorcerer" (Deuteronomy 18:10). The New Testament also condemns magic: Acts 19:19 describes converts burning their magical books. Revelation 21:8 lists sorcerers among those condemned to the lake of fire.
Church Fathers: Early Christian theologians (Augustine, Tertullian, Origen) condemned magic as: Demonic (all magic comes from demons, not God). Idolatrous (magic worships false gods or spirits). Deceptive (demons lie and lead souls to damnation). Unnecessary (Christians have prayer, sacraments, and divine graceβwhy use magic?).
Medieval Church Councils
Council of Laodicea (364 CE): Condemned astrology, divination, and magical amulets. Prohibited clergy from practicing magic (on pain of defrocking).
Council of Toledo (633 CE): Condemned magic and divination. Ordered magical books to be burned. Prescribed penance for those who consulted magicians.
Fourth Lateran Council (1215): Reaffirmed condemnation of magic. Emphasized the sacraments as the only legitimate supernatural power. Prohibited clergy from involvement in magic or superstition.
Papal Bulls and Decrees
Pope John XXII, Super illius specula (1326): Condemned magic, especially necromancy (summoning the dead). Declared magic to be heresy (not just sin, but rejection of the faith). Authorized the Inquisition to prosecute magicians.
Pope Innocent VIII, Summis desiderantes affectibus (1484): The "Witch Bull." Authorized the Inquisition to prosecute witchcraft in Germany. Led to the publication of the Malleus Maleficarum ("Hammer of Witches," 1487). Intensified witch hunts across Europe.
Pope Sixtus V, Coeli et terrae Creator (1586): Condemned astrology (especially judicial astrologyβpredicting the future). Banned astrological books. Declared astrologers to be heretics.
The Inquisition
What It Was: A Church tribunal established to identify and prosecute heresy. Founded in the 12th century (to combat Catharism and other heresies). Expanded in the 13th century (Dominican and Franciscan inquisitors). Reached its peak in the 15th-17th centuries (Spanish Inquisition, witch trials).
Magic as Heresy: The Inquisition prosecuted: Necromancy (summoning the dead or demons). Divination (fortune-telling, astrology). Possession of grimoires (evidence of magical practice). Heretical beliefs (e.g., that magic could compel God or angels). Punishments ranged from penance to imprisonment to execution (burning at the stake).
Which Grimoires Were Banned?
The Index Librorum Prohibitorum
What It Was: The "Index of Prohibited Books." A list of books Catholics were forbidden to read (on pain of excommunication). First published in 1559 (by Pope Paul IV). Updated regularly until 1966 (when it was abolished).
Grimoires on the Index: Many grimoires were explicitly banned: The Key of Solomon (Clavicula Salomonis). The Lesser Key of Solomon (Lemegeton). The Grand Grimoire (Le Grand Grimoire). The Grimorium Verum. The Sixth and Seventh Books of Moses. Agrippa's Three Books of Occult Philosophy (banned in some editions). The Picatrix (condemned but not always formally indexed).
Why These Grimoires?
Demon Summoning: Grimoires that taught how to summon demons were the most condemned. The Ars Goetia, Grand Grimoire, and similar texts were seen as explicitly demonic. Even if the grimoire claimed to command demons "by God's authority," the Church saw this as blasphemy.
Divination and Astrology: Grimoires that taught divination (predicting the future) were condemned. The Church taught that only God knows the future. Attempting to know it through magic was usurping God's knowledge. Astrology was especially controversial (some Church scholars accepted it, others condemned it).
Pacts with Demons: Any grimoire that involved making pacts with demons (like the Grand Grimoire) was absolutely forbidden. This was seen as selling your soul to the Devil. It was the ultimate heresy.
Grimoires That Escaped Condemnation (Sometimes)
"Natural Magic" Texts: Some grimoires framed magic as "natural philosophy" or "natural magic." They claimed to work with natural forces (not demons). Examples: Parts of the Picatrix (planetary magic, talismans). Agrippa's Book I (natural magic). Ficino's De Vita Coelitus Comparanda ("On Obtaining Life from the Heavens"). These texts were controversial but sometimes tolerated (especially if the author was a respected scholar or had Church connections).
"Angelic Magic" Texts: Grimoires that focused on angels (not demons) were less condemned. The Sworn Book of Honorius (angelic invocations, Beatific Vision). The Book of Abramelin (Holy Guardian Angel). John Dee's Enochian magic (angelic language). The Church was ambivalent: invoking angels could be legitimate (saints did it). But it could also be presumptuous or demonic (demons can disguise themselves as angels).
The Paradox: Why Monks Copied Grimoires
Intellectual Curiosity
Monks Were Scholars: Medieval monks were among the most educated people in Europe. They read Latin, Greek, and sometimes Hebrew and Arabic. They studied theology, philosophy, astronomy, medicine, and natural philosophy. They were curious about all forms of knowledgeβincluding forbidden knowledge.
Copying as Study: Copying a text was a way to study it deeply. Scribes had to read every word, understand the structure, and engage with the content. Monks may have copied grimoires out of intellectual curiosity ("What does this text say? How does it work?"). They may not have intended to practice the magicβjust to understand it.
Preservation of Knowledge
Monks as Librarians: Monasteries were the libraries of the Middle Ages. Monks saw themselves as preservers of knowledge (even controversial knowledge). They copied texts to prevent them from being lost. They may have believed: "This text is dangerous, but it's also part of human knowledge. We should preserve it (even if we don't approve of it)."
Historical Precedent: Monks preserved many "pagan" texts (Greek and Roman philosophy, mythology, etc.). They didn't agree with paganism, but they valued the knowledge. Grimoires may have been treated similarly ("We don't approve, but we'll preserve it for posterity").
Theological Justification
"Natural Magic" vs. "Demonic Sorcery": Some monks distinguished between: Natural magic: Understanding hidden natural laws (e.g., the properties of herbs, stones, stars). This was seen as legitimate natural philosophy (not heresy). Demonic sorcery: Summoning demons, making pacts, using magic to harm others. This was absolutely forbidden. Grimoires that focused on natural magic (like parts of the Picatrix or Agrippa's Book I) could be justified as natural philosophy. Monks could copy them without (in their minds) violating Church teaching.
"Angelic Magic" as Prayer: Some grimoires (like the Sworn Book of Honorius) frame magic as prayer. Invoking angels, seeking divine visions, achieving union with God. Monks could see this as an extension of monastic practice (contemplation, mysticism, prayer). The line between mystical prayer and angelic magic was blurry. Some monks may have crossed it (intentionally or unintentionally).
Secret Networks and Heterodoxy
Not All Monks Were Orthodox: The Church was not monolithic. Some monks held heterodox (non-standard) beliefs. Some were interested in Kabbalah, Hermeticism, or alchemy. Some were part of secret networks (sharing forbidden texts, discussing esoteric ideas). These monks may have copied grimoires because they genuinely believed in magic (or at least found it fascinating).
The "Council of 89 Magicians": The Sworn Book of Honorius claims to be the work of 89 magicians (possibly including clergy). While this is likely fiction, it reflects a reality: there were networks of magicians (some of whom were clergy or monks). These networks preserved and transmitted grimoires.
Personal Spiritual Practice
Mysticism and Magic: Some monks were mystics who sought direct experience of God. They practiced: Intense prayer and meditation. Fasting and asceticism. Visions and ecstasies. Some may have used grimoire techniques (angelic invocations, divine names, sacred geometry) as part of their mystical practice. They may have seen grimoires as tools for spiritual ascent (not sorcery).
The Beatific Vision: The Sworn Book of Honorius teaches how to achieve the Beatific Vision (seeing God). This is a legitimate Christian goal (saints and mystics experienced it). A monk might copy this grimoire thinking: "This is a method for achieving what I already seek through prayer. It's not sorceryβit's advanced mysticism."
The Inquisition and Grimoire Trials
Famous Cases
Cecco d'Ascoli (1269-1327): Italian astrologer and physician. Wrote a commentary on the Sphere (an astronomical text). Accused of heresy for practicing astrology and magic. Burned at the stake in Florence (1327). His books were burned with him.
Giordano Bruno (1548-1600): Italian philosopher and magician. Used Hermetic and magical ideas (influenced by the Picatrix and Agrippa). Accused of heresy (for many reasons, including magic). Burned at the stake in Rome (1600). His magical practices were part of the charges against him.
Urbain Grandier (1590-1634): French priest accused of witchcraft. Allegedly possessed nuns in Loudun, France. Found with a grimoire (or accused of using one). Burned at the stake (1634). The case was politically motivated, but grimoires were used as evidence.
What Happened to Grimoires in Trials?
Evidence of Heresy: Owning a grimoire was evidence of magical practice. Inquisitors would search homes and libraries for grimoires. Finding one could lead to arrest, torture, and execution.
Public Burning: Grimoires were often burned publicly (along with the accused magician). This was meant to: Destroy the dangerous knowledge. Demonstrate the Church's power over heresy. Warn others not to practice magic. Many grimoires were lost this way (we only have the ones that survived).
Confiscation and Preservation: Some grimoires were confiscated by the Inquisition and kept (not burned). They were stored in Church archives (as evidence or for study). Ironically, the Inquisition preserved some grimoires (by confiscating them instead of burning them). The Vatican Library contains grimoires confiscated during trials.
Where Surviving Grimoires Are Today
The Vatican Library
The Vatican Secret Archives: Contains thousands of manuscripts, including grimoires. Many were confiscated by the Inquisition. Others were donated by scholars or clergy. Examples: Manuscripts of the Key of Solomon. Copies of the Sworn Book of Honorius. Astrological and alchemical texts. Access is restricted (scholars must apply for permission).
The British Library
Sloane Collection: Sir Hans Sloane (1660-1753) collected manuscripts, including grimoires. Many came from dissolved monasteries (after the English Reformation). Examples: Sworn Book of Honorius (Sloane MS 3854). Key of Solomon (multiple manuscripts). Ars Notoria and other magical texts. These are now publicly accessible (digitized online).
Bibliothèque Nationale de France
French National Library: Contains many French grimoires: Grand Grimoire manuscripts. Grimorium Verum. French versions of the Key of Solomon. Many came from private collections or dissolved religious houses.
Other Collections
Bodleian Library (Oxford): Contains grimoires and magical manuscripts (some from monastic libraries). Wellcome Library (London): Medical and alchemical manuscripts (including magical texts). Private Collections: Some grimoires are in private hands (collectors, occultists, scholars). Occasionally sold at auction (for high prices).
How the Church Both Destroyed and Preserved Magic
Destruction
Burnings: Countless grimoires were burned (along with their owners). Public burnings during witch trials. Private burnings by repentant magicians or fearful owners. We'll never know how many grimoires were lost.
Suppression: The Church suppressed magical knowledge through: Condemnation (papal bulls, councils). The Index (banning books). The Inquisition (prosecuting magicians). Fear (people hid or destroyed grimoires to avoid accusation). This drove magic underground (making it secretive and dangerous).
Preservation
Monastic Copying: Monks copied grimoires (for the reasons discussed above). Without them, many grimoires would have been lost. The Church (through its monks) preserved what it officially condemned.
Confiscation: The Inquisition confiscated grimoires (instead of always burning them). These were stored in Church archives. Ironically, the Church became the custodian of forbidden knowledge.
Theological Engagement: Church scholars engaged with magic (to refute it). They read grimoires, studied magical philosophy, and wrote treatises against magic. This engagement preserved magical ideas (even in the act of condemning them). Example: Thomas Aquinas wrote about magic (to condemn it), but his writings preserve magical concepts.
The Paradox
The Church's Contradictory Role: The Church was magic's greatest enemy (condemning, prosecuting, burning). The Church was also magic's greatest preserver (copying, confiscating, archiving). Without the Church, we might have more grimoires (no suppression). Without the Church, we might have fewer grimoires (no monastic copying, no archives). The relationship is paradoxical and inseparable.
The Thin Line: Prayer vs. Spell, Saint vs. Sorcerer
Similarities Between Magic and Religion
Invocation: Magic: Invoking angels or demons by name. Religion: Praying to saints or angels by name. The structure is similar (calling on a spiritual being for help).
Ritual: Magic: Circles, tools, timing, gestures, words of power. Religion: Liturgy, sacraments, vestments, prayers, sacred words. Both use ritual to access the sacred.
Symbols: Magic: Pentacles, seals, sigils, divine names. Religion: Crosses, icons, relics, the name of Jesus. Both use symbols as conduits of power.
Transformation: Magic: Seeks to transform the self or the world through supernatural means. Religion: Seeks salvation, sanctification, union with God. Both aim for transformation.
The Difference (According to the Church)
Source of Power: Magic: Power comes from the magician's knowledge, will, or pact with spirits. Religion: Power comes from God's grace (not human effort). Magic is presumptuous (trying to compel God or spirits). Religion is humble (asking God for help).
Intent: Magic: Often for worldly gain (wealth, love, power). Religion: For spiritual good (salvation, virtue, God's glory). Magic is selfish. Religion is selfless.
Authority: Magic: The magician acts on their own authority (or through spirits). Religion: The priest acts on the Church's authority (ordained by God). Magic is unauthorized. Religion is authorized.
The Blurry Line
In Practice, the Line Was Blurry: Some saints performed miracles that looked like magic (healing, exorcism, visions). Some magicians framed their work as prayer (invoking God and angels). Some grimoires (like the Sworn Book of Honorius) are indistinguishable from mystical prayer books. The Church tried to maintain a clear distinction, but in practice, it was often unclear. This is why monks could copy grimoires (they could justify it as "not really magic").
Conclusion: The Church's Paradox
The Church condemned magic as heresy, demonic, and damnable. It prosecuted magicians, burned grimoires, and declared magic to be the work of the Devil.
And yet, the Church also preserved magic. Monks copied grimoires in secret. The Inquisition confiscated and archived magical texts. Church scholars engaged with magical philosophy (even to refute it).
The result: many of the grimoires we have today survived because of the Churchβthe very institution that tried to destroy them.
This is the paradox. The Church was magic's greatest enemy and its greatest preserver. It condemned grimoires and copied them. It burned magicians and archived their books.
Why? Because the line between prayer and spell, between saint and sorcerer, between mysticism and magic, was never as clear as the Church wanted it to be.
The monks who copied grimoires knew this. They lived in the paradox. And because of them, the grimoires survived.
In the final article, we'll explore modern grimoiresβfrom Aleister Crowley's Book of the Law to chaos magic's sigil grimoires, and how the grimoire tradition evolved (and exploded) in the 20th and 21st centuries.
The monk copies by candlelight. The grimoire is forbidden. The Church condemns it. But the monk's hand moves, the quill scratches, the words are preserved. Prayer or spell? Saint or sorcerer? The line is thin. The paradox remains. And the grimoire survives.
As we reflect on the sacred and secretive history of grimoires preserved by cloistered hands, it becomes clear that honoring these traditions can deepen our own magical practice today. You might explore the structured wisdom of a 30 day tarot practice workbook to mirror the discipline of those ancient scribes, or align your intentions with the celestial rhythms that guided monk copyists through a cosmic alignment ritual kit for syncing with the celestial flow. For those drawn to the protective and revelatory symbols that adorned illuminated manuscripts, the tarot the moon tapestry offers a daily reminder of the mystic bridge between the earthly and the divine.
