Heretical Texts: Books the Church Tried to Burn
Share
Introduction: The Books That Wouldn't Die
For centuries, the Church waged war not just on heretics, but on their books. The Index of Forbidden Books (Index Librorum Prohibitorum, 1559-1966) listed thousands of texts Catholics were forbidden to read. Inquisitors burned libraries. Popes ordered the destruction of Gnostic gospels, Hermetic texts, and Kabbalistic writings.
Yet the forbidden knowledge survived. Hidden in caves, copied in secret, smuggled across borders, these "heretical" texts preserved wisdom the Church tried to erase. Today, we can read the Gospel of Thomas, study the Zohar, and explore the Hermetic Corpus—texts that were capital crimes to possess just centuries ago.
This is the ninth article in our Heretics & Mystics series. We now explore the forbidden texts, why they were dangerous, how they survived, and how to read them today.
The Gnostic Gospels
The Gospel of Thomas
What it is: Collection of 114 sayings attributed to Jesus
Date: Written c. 50-140 CE (possibly earlier than canonical gospels)
Discovered: 1945, Nag Hammadi, Egypt
Language: Coptic (translated from Greek)
Why dangerous:
- No crucifixion or resurrection narrative (challenges core Christian doctrine)
- Emphasizes self-knowledge over faith: "If you bring forth what is within you, what you bring forth will save you"
- Jesus as wisdom teacher, not sacrificial savior
- Kingdom of God is within, not future event
Famous sayings:
- "The kingdom of the Father is spread out upon the earth, and people do not see it." (Saying 113)
- "Jesus said, 'If your leaders say to you, "Look, the kingdom is in the sky," then the birds of the sky will precede you. If they say to you, "It is in the sea," then the fish will precede you. Rather, the kingdom is within you and it is outside you.'" (Saying 3)
Modern availability: Widely published, studied by scholars
The Gospel of Mary (Magdalene)
What it is: Dialogue between risen Jesus and disciples, featuring Mary Magdalene
Date: c. 120-180 CE
Discovered: 1896, Egypt (Berlin Codex); additional fragments 1945 (Nag Hammadi)
Why dangerous:
- Mary Magdalene as leading disciple
- Receives special revelation from Jesus
- Peter jealous of her authority: "Did he really speak with a woman in private without our knowledge?"
- Levi defends her: "If the Savior made her worthy, who are you to reject her?"
- Challenges male apostolic authority
Missing pages: 10 of 18 pages lost (frustrating gaps)
Impact: Feminist reclamation of Mary Magdalene as apostle, not prostitute
The Gospel of Judas
What it is: Conversation between Jesus and Judas
Date: c. 130-170 CE
Discovered: 1970s, Egypt; published 2006 by National Geographic
Why dangerous:
- Judas as hero, not villain
- Jesus asks Judas to betray him (part of divine plan)
- Other disciples worship false god (Demiurge)
- Only Judas understands Jesus's true mission
Controversy: Translation disputed; some scholars question interpretation
The Gospel of Philip
What it is: Collection of Gnostic sayings and theology
Date: c. 180-250 CE
Discovered: 1945, Nag Hammadi
Why dangerous:
- Mary Magdalene as Jesus's "companion" (possibly wife)
- "The companion of the Savior is Mary Magdalene. Christ loved her more than all the disciples and used to kiss her often on her [mouth]."
- Sacramental theology different from orthodox
- Bridal chamber as sacred mystery
Note: "Companion" (koinonos) could mean spouse, partner, or close associate
The Zohar: Kabbalistic Secrets
What It Is
Full title: Sefer ha-Zohar ("Book of Splendor")
Content: Mystical commentary on Torah, foundation of Kabbalah
Date: Published 13th century by Moses de León (Spain)
Claimed authorship: Shimon bar Yochai (2nd century CE rabbi)
Actual authorship: Debated (likely Moses de León, possibly drawing on earlier sources)
Core Teachings
The Sefirot: Ten emanations of God
- Keter (Crown), Chokhmah (Wisdom), Binah (Understanding)
- Chesed (Mercy), Gevurah (Severity), Tiferet (Beauty)

- Malkhut (Kingdom)
Ein Sof: The Infinite, unknowable God beyond Sefirot
Four Worlds: Atziluth (Emanation), Briah (Creation), Yetzirah (Formation), Assiah (Action)
Mystical interpretation: Every word, letter, even space in Torah has hidden meaning
Why Dangerous
To Judaism:
- Seemed to compromise monotheism (ten Sefirot = multiple gods?)
- Mystical interpretation challenged rabbinic authority
- Accessible to non-scholars (written in Aramaic, not Hebrew)
To Christianity:
- Jewish mysticism = threat
- Christians who studied Kabbalah suspected of heresy
- Inquisition targeted Christian Kabbalists
Restrictions:
- Traditionally, only married Jewish men over 40 could study
- Required extensive Torah knowledge first
- Dangerous if misunderstood
Modern Availability
- Fully translated into English (Pritzker Edition, 12 volumes)
- Studied by Jews, Christians, occultists, scholars
- Influenced Western esotericism (Golden Dawn, Theosophy, etc.)
The Hermetic Corpus
What It Is
Collection: Greek and Latin texts attributed to Hermes Trismegistus ("Thrice-Great Hermes")
Date: Written c. 100-300 CE (Egypt, under Roman rule)
Claimed origin: Ancient Egyptian wisdom from god Thoth/Hermes
Actual origin: Greco-Egyptian synthesis (Greek philosophy + Egyptian religion)
Major Texts
Corpus Hermeticum: 18 treatises
- Poimandres: Vision of creation and fall of humanity
- The Discourse on the Eighth and Ninth: Mystical ascent
- The Key: Dialogue on divine knowledge
Asclepius: Latin Hermetic text
Emerald Tablet: Short alchemical text
- "As above, so below"
- Foundation of Western alchemy
Core Teachings
- Gnosis: Salvation through knowledge of divine
- Microcosm/Macrocosm: Human as miniature universe
- Ascent of soul: Through planetary spheres to divine
- Rebirth: Spiritual transformation in this life
- All is One: Unity of all existence
Why Dangerous
To early Christianity:
- Pagan philosophy competing with Gospel
- Salvation through knowledge, not faith in Christ
- Magic and astrology (forbidden practices)
Renaissance revival:
- 1460s: Marsilio Ficino translated Corpus Hermeticum
- Believed to be ancient Egyptian wisdom (predating Moses)
- Influenced Renaissance magic, alchemy, philosophy
- Church suspicious but tolerated (until proven later date)
1614: Isaac Casaubon proved texts were not ancient (written in early Christian era)
- Discredited as "ancient wisdom"
- But still influential in esotericism
Modern Availability
- Multiple English translations
- Studied by scholars, occultists, philosophers
- Influenced New Age, Hermeticism, Western esotericism
Other Forbidden Texts
The Talmud
What: Rabbinic commentary on Jewish law and tradition
Why burned:
- Church claimed it blasphemed Jesus and Mary
- 1242: Paris, 24 cartloads of Talmud burned
- Repeated burnings throughout Middle Ages
Survival: Jews continued copying and studying in secret
Works of Aristotle
Why forbidden:
- Pagan philosophy
- Contradicted Church teachings (eternal universe, no personal immortality)
- 1210-1277: Various bans on teaching Aristotle
Irony: Thomas Aquinas later synthesized Aristotle with Christianity (became orthodox)
Vernacular Bibles
Why forbidden:
- Church wanted Bible in Latin (controlled by clergy)
- Translating into common languages = heresy
- John Wycliffe's English Bible (1380s) condemned
- William Tyndale executed for English translation (1536)
Result: Protestant Reformation made vernacular Bibles standard
The Malleus Maleficarum
Irony: Witch-hunting manual, not forbidden but should have been
Why mentioned: Shows Church approved terrible texts while banning wisdom
The Index of Forbidden Books (1559-1966)
What It Was
Official name: Index Librorum Prohibitorum
Created: 1559 by Pope Paul IV

Conclusion: The Knowledge That Survived
The Church tried to burn the Gnostic gospels, ban the Zohar, and suppress the Hermetic Corpus. Inquisitors destroyed libraries, executed those who possessed forbidden books, and created an Index of thousands of banned titles. Yet the knowledge survived—hidden in caves, copied in secret, preserved by those who risked death to protect wisdom.
Today, we can freely read what was once forbidden. The Gospel of Thomas, the Zohar, the Hermetic Corpus—texts that were capital crimes to possess—are now available online, in bookstores, in libraries. The Church's war on knowledge failed.
In the final article of this series, we will explore Modern Heretics: Persecution Continues. We will examine contemporary religious persecution, the stigmatization of new religious movements, and how to protect the right to spiritual freedom today.
The books wouldn't burn. The knowledge wouldn't die. And the truth endures.
For the texts that survived. For those who preserved them. For the freedom to read what was forbidden. We remember.
As you explore the forbidden wisdom and hidden currents that the old world sought to extinguish, remember that true illumination often comes from the shadows—let these uncovered truths guide your own sacred journey, perhaps deepened by the introspective depths of the tarot journaling prompts 100 questions for self discovery to map your inner revelations, or by aligning with the celestial flow through the cosmic alignment ritual kit for syncing with the celestial flow to anchor rebellious insights in the stars, and finally, grounding your newfound gnosis with the protective wisdom of the jung and the archetype tarot astrology and the bridge of the unconscious to bridge the heretical with the divine.
