In my long-running Rhine saga, quite occasionally I like to produce meaty handouts. Here is the latest one that might be fun for others to borrow from when dealing with the Church.
Very Belated Update: I've also posted my writeup listings for the books in this analysis here: Bibliotheca Mundana - A selection of Historical Books
© 2026 OriginalMadman. Licensed under CC BY-SA 4.0.
The quick background is that this is after session #172 where the Verditius player Lorenzo (prone to zealotry after ablating a fanatical crusader and botching) used his knowledge of Theology (and rolled well) to analyze the covenants potential issues (particularly the library books) as they've been warned by formal letter from the Vatican that Konrad von Marburg (the infamous historical inquisitor to Germany) will eventually make a follow-up visit to an earlier legate visit (that went reasonably well). I posted this letter earlier on the forum. Now they want to be diligent and understand the challenges - which could translate straight to any other covenant around this time (1232 in the current saga). They are on good foot with the papal legate, and saved his hide from demons in Hamm in an earlier session where they witnessed plenty of bad things. However, this means they got the Church's eye on them - and Lorenzo himself was quoted as being noted by the pope for his stoic resistance and banishment of an Infernal demon (perhaps not the attention you'd want but here we are). Of course the Church has a myopic view of holy/unholy that doesn't really fit in magi or magic. Hope you enjoy.
Note: I've machine translated, but manually corrected, to English - as the original is in Swedish. Some AI-isms sneak into the translation such as over-liberous use of em-dash (I use none or few in my writing). Sorry I'm not removing them -- it's correct use of language, if annoying). I think I found the few errors (translations are getting great nowadays, I'm loving it).
Handout: Theological Analysis in Preparation for the Inquisitorial Visit
The Inquisition differs fundamentally from an ordinary system of justice:
- There is no accusing party — the inquisitor acts on his own initiative, on rumour, on anonymous testimony
- The accused is not normally permitted to know who has testified against him
- The inquisitor may summon anyone to examination: servants, neighbours, passing merchants
- Testimony is given under oath, with the threat of excommunication for perjury
- Torture is technically not permitted (note: prior to the bull Ad extirpanda of 1252), but individual inquisitors may hold papal dispensation to deviate from normal procedure
A Church inquisitor in the year 1232 does not work primarily from a general list of forbidden books — no such Index exists formally (yet). Instead, he seeks evidence in three categories, ranked by severity:
I. Organised Heresy — The Absolute Priority
Konrad von Marburg's mandate is to destroy societies of heretics: Cathar networks, Luciferians, groups bound by shared secret ritual and common doctrine. A solitary superstitious peasant is a bishop's problem. An organised society with a library, a laboratory, and internal hierarchies is an inquisitor's problem. What makes a covenant extraordinarily dangerous is precisely that it resembles an organised society — communal residence, secret knowledge, internal rules, and a library that constitutes a shared intellectual project.
II. Active Communication with Demons or Pagan Gods
Every ritual, text, or object that indicates contact with supernatural entities outside the divine order — God's angels, the Virgin Mary, the saints — is by definition demonic communication. It does not matter whether the practitioner calls it "natural forces" or "magic without demons." Augustine's legacy is clear: magic that operates without God's sacraments operates through the Devil's assistance.
III. Possession of Concretely Condemned Material
Books and texts explicitly condemned by papal decree, church councils, or synods constitute legal evidence in themselves. No proof of use is required — ownership suffices. The inquisitor proceeds from:
-
Concrete ecclesiastical condemnations (synods, papal decrees)
-
Who owns the book and to what end
-
Whether the text is used to summon demons or supports heretical views
Library Books — Risk Assessment
Likely No Objection
Consolatio Philosophiae — Boethius, transl. Alfred (Philosophiae tractatus, Q9)
Boethius — executed in 524 by the Arian Ostrogothic king Theoderic, and long venerated almost as a martyr. His work unites Christian theology with Neoplatonic philosophy. The Consolation is read and cherished by the learned across all of Europe. That Alfred the Great, England's Christian king par excellence, produced a translation lends the book additional legitimacy. An inquisitor would likely lift it with reverence.
De Initio Creaturae — Ælfric of Eynsham
One of the four books the covenant was asked to conceal may not be so > dangerous after all.
Ælfric was among the most respected Benedictine monks of the Anglo-Saxon tradition — a pupil of Æthelwold of Winchester, one of the cornerstones of the reform movement, and a prolific, consistently orthodox theologian. His angelology — the doctrine of the angels' creation, Lucifer's fall, and the purpose of humanity in filling the heavenly choir — is not controversial; it traces directly to Gregory the Great's Homilies and is well accepted in thirteenth-century Church teaching.
The doctrine of the ten angelic choirs, reduced to nine by Lucifer's revolt, and that mankind was created to restore the tenth, is theologically mainstream and appears explicitly in High Scholastic theology. It is not speculative esotericism but pastoral theology: why do we exist? Because we are destined to take the place of the fallen angels in the presence of God.
The fact that Ælfric is more interested in angels than Bede makes him a better source on angelology — not a suspect. An inquisitor of theological learning sees a holy work by a celebrated Anglo-Saxon teacher.
Likely verdict: No objection. Pure orthodox theology, traceable to the Church Fathers.
De Temporum Ratione — Bede (Artes Liberales, Q10)
Beda Venerabilis is a name venerated in Church tradition as near-saintly. His work on time-reckoning and the calculation of Easter — the computus — is orthodox, widely known, and has been actively recommended by the Church's educational system since the ninth century. That the book addresses the spherical shape of the earth and astronomical observations falls entirely within accepted cosmology. No inquisitor would raise an eyebrow.
Elementa — Euclid (Artes Liberales, level 4, Q8)
Geometry is part of the quadrivium and was regarded as a pure intellectual instrument for understanding God's order. Studying the properties of a triangle does not violate theology. Euclid was a pagan, but his mathematics contains no religious content whatsoever. An inquisitor should pass this book without a second glance.
Institutione Grammaticae — Priscian (Artes Liberales, level 5, Q9)
Latin grammar has been a cornerstone of monastic education since the Carolingian schools. Priscian was a late antique teacher whose work has circulated through monastic scriptoria for four hundred years. To have this in a library is like having a bread oven in the kitchen — expected and entirely unremarkable.
Likely Acceptable — With a Minor Asterisk
Canon of Medicinae — Avicenna (Medicina, level 6, Q9)
Gerard of Cremona's Latin translation is the de facto standard text at European medical schools. The universities of Salerno and Bologna use it actively. The fact that Avicenna was a Muslim who wrote hundreds of philosophical works beyond the medical Canon is potentially problematic — but this book is pure medicine, without theological dynamite. An inquisitor with a good education should know that Avicenna existed and was a Muslim, but the Canon's medical standing is too well established to challenge without political motivation.
Risk level: Low — provided the inquisitor does not know who Avicenna truly was as a philosopher.
The Galen Works (Medicina tractatus, Q11)
Galen is, alongside Hippocrates, the medical authority of Europe. Latin texts of Galen in a library are what one is expected to possess. The following works are all pure medicine, in Latin, without religiously controversial content — an inquisitor should nod and move on:
-
De Alimentorum Facultatibus
-
De Anatomicis Administrationibus
-
De Medendi Methodo
-
De Motu Thoracis et Pulmonis
-
De Ossibus
-
De Remediis Paratu Facilibus
-
De Temperamentis (standard version)
-
De Usu Pulsuum
-
De Venæsectione
One exception: De Dignotione ex Insomniis (On Diagnosis Through Dreams)
Galen uses dreams as a diagnostic tool and explicitly invokes the god Asclepius as their source. A well-educated inquisitor knows that dream interpretation borders on oneiromancy — divination through dreams — which is forbidden. That Galen presents it as rational medicine helps, but his reference to a pagan god delivering divine messages through sleep is theologically uncomfortable. The book would likely not be confiscated, but would give a suspicious inquisitor reason to ask why it is owned and how it is used.
Questionable — Likely Requires an Explanation
Categories & On Interpretation — Aristotle, commented by Averroes (Philosophiae, Q11)
A distinction must be drawn between two layers:
The Aristotle texts themselves — the Logica Vetus — were approved by Robert de Courçon in 1215 and belong to the normal university curriculum. They are not among the forbidden natural-philosophical works.
Averroes' commentaries are another matter. Averroes taught that the human intellect is single and universal — meaning your personal soul does not survive death as your soul. His doctrine of "double truth" (that what is philosophically true may differ from what is theologically true) is held to directly undermine the authority of faith. The sea-battle passage in De Interpretatione illuminates determinism in ways that touch upon free will, predestination, and divine foreknowledge — a theological adviser would flag this immediately.
Likely verdict: An inquisitor who understands what he sees will confiscate the Averroes commentaries but leave the Aristotle texts.
De Operationes Daemonum Dialogus — Michael Psellos
Psellos (c. 1018–1078) was one of Byzantium's most influential philosophers and administrators. His Dialogus classifies demons into six categories: the fiery, the aerial, the aquatic, the terrestrial, the subterranean, and the light-shunning (lucifugous). Written as a Socratic dialogue between "Timotheus" and "the Thracian," the work's status is genuinely ambiguous:
Argument for acceptability: Psellos was a theologian and Church functionary. He writes about demons to classify and understand them — not to invoke them. Demonological classification can be pastorally justified: exorcists need to know what they confront.
Argument for danger:
-
Psellos describes in detail the secret rituals of the Massalians/Euchites — not abstract theology but an operational account
-
The Massalians were heretical sects condemned by Church councils since the 380s; detailed accounts of their rituals risk serving as recruitment material
-
The manuscript has been copied by many different hands — the most alarming detail of all. Why would multiple hands copy an esoteric Byzantine demonological dialogue? Not for theological instruction: because it describes how demons operate practically. Demand reveals intent.
-
To own a rare Byzantine work — from a Church whose relationship with Rome has been deeply complicated since the Great Schism of 1054 and the Latin conquest of Constantinople in 1204 — means an inquisitor need not even concede the text's orthodox intention
Likely verdict: A prudent inquisitor will seize it and interrogate the owner about why it is needed and who copied it.
Fons Vitae — Avicebron (Philosophiae, level 4, Q11)
The decisive factor here is what the inquisitor knows. Most scholars do not know that Avicebron was the Jewish poet Solomon ibn Gabirol — the author is assumed to be a Muslim, or perhaps a Christian. An inquisitor may read it as a Neoplatonic work of obscure Arabic origin. Its content is deeply influenced by Neoplatonism — as Augustine is — and is in fact well regarded by certain theologians such as William of Auvergne, Bishop of Paris, who cited Avicebron extensively.
Risk factor: Neoplatonic speculation that all matter is permeated by form (hylomorphism) could be misread as pantheism — the doctrine that God is matter. This becomes a problem if the inquisitor brings a theologian who knows what the text actually says.
Directly Heretical — Potentially Fatal to Be Found With
De Temperamentis (Galen) — the hidden pages
The standard Galen text presents no problem. But the pages glued and concealed within are a death warrant under the right — or wrong — circumstances. Instructions for "drawing power from the underworld" — the chthonic — risk being read as precisely what the Luciferians are accused of: invoking powers from beneath the earth, demonic entities, the kingdom of darkness. That Hades is named explicitly may be damning — an inquisitor readily equates the worship of pagan gods with devil-worship without distinction, as the reports to the Pope regarding the Luciferians' sabbath rituals demonstrate.
The fact that these pages are concealed within an otherwise legitimate medical text makes it considerably worse — it demonstrates dolus, a deliberate will to hide the forbidden. It is the legal equivalent of being caught in the act.
Liber Apologeticus — Priscillian of Ávila
This is the historically most compromised book in the collection. Priscillian was the first Christian executed for heresy: put to death in 385 AD as the first Christian killed by Christians on charges of heresy. The formal accusation was sortilegia (sorcery) and Manichaeism.
Historical note: Bishops Ambrose of Milan and Martin of Tours protested the > execution vigorously as theologically improper. It was the secular imperial > power that carried out the sentence.
The cited passage is a precise rendering of Cathar/Manichaean dualism — exactly what the Inquisition is hunting:
| Passage | Inquisitor's Reading |
|---|---|
| "Flesh and spirit, darkness and light" | The fundamental Manichaean dichotomy |
| "Moses and Christ" as separate divine figures | Old Testament God (matter/darkness) vs New Testament God — precisely Cathar doctrine |
| "The prince of this world" separate from Christ | The Cathar Rex Mundi, the evil god who rules matter |
| "The perfect" (perfecti) | The exact term for the Cathar initiated elite |
| "Three degrees of asceticism" | Echoes the Cathar distinction between credentes and perfecti |
All papal inquisitors know Catharism intimately and would immediately read Priscillian's text as an ancient precursor to the very heresy they are hunting in Languedoc and the Rhineland.
The excised pages are not a trivial matter. Who removed them? A previous owner who knew what they contained and wished to conceal the worst? Or one who wished to preserve it elsewhere? The inquisitor sees deliberate manipulation — conscious censorship of the most heretical material, while the milder content was allowed to remain.
Likely verdict: Immediate confiscation and interrogation of everyone in the house regarding the book's provenance and the missing pages.
Scito te Ipsum (Know Thyself) — Pierre Abélard (Philosophiae tractatus, Q13)
This is the most explosive book in the outer collection. Abélard was condemned twice:
-
1121, Council of Soissons — forced to burn his own book with his own hands
-
1140/41, Council of Sens — Bernard of Clairvaux, the most powerful religious voice in Europe, personally led the prosecution. Pope Innocent II confirmed the judgement in 1141, sentencing Abélard to perpetual silence in a monastery and condemning his writings, which the Council of Sens had ordered burned wherever they were found.
Scito te Ipsum is specifically condemned: Abélard's doctrine that sin is intention rather than outward act, and that Christ did not truly atone for sin but merely demonstrated God's love (the moral influence theory), is held to be directly heretical.
To possess a copy of this work is not merely suspicious — it is an explicit breach of papal mandate. An inquisitor who finds this book has just acquired a concrete legal case against the owner.
Testamentum Verum Regis Salomonis
It is essential to understand that the Ars Notoria is not something an inquisitor needs to read in all four languages to classify. Known in limited circles and already a partially persecuted phenomenon, it promises immediate mastery of all human and divine arts through ritual prayers and sigils. The inquisitor's logic is straightforward: natural learning takes years. Supernatural rapid acquisition of knowledge outside the path of divine grace can come from only one alternative source — demons. That the promised knowledge seems useful and pious makes it more, not less, dangerous. This is precisely how the Devil is understood to operate.
The book's very structure is incriminating:
-
Four languages (Latin, Greek, Hebrew, Chaldean/Aramaic) — esoteric knowledge reserved for the initiated is a heresiological pattern; the Church's learning is open and accessible
-
Geometric figures with animal heads and distorted human forms — an inquisitor recognises magical sigil patterns from confiscated necromantic texts
-
"The Tree of Life" — Etz haChayim is a central Kabbalistic concept; its symbols are perceived as Jewish magic
-
"Interlocking circles and knots" — identical structures appear in Islamic talisman traditions and in necromantic sigil manuscripts
That the text superficially praises God, Solomon, and the artes liberales makes it more, not less, suspicious — this is precisely the camouflage a sophisticated demonic deceiver is held to employ.
Likely verdict: Confiscated immediately. Possession of this book alongside the hidden chthonic pages in the Galen volume could suffice to motivate an investigation of the entire premises as an organised occult society.
Hermeticism — Magical Theory and Spells
The critical theological distinction in the Church's emerging theoretical framework is between natural magic and demonic magic:
-
Magia naturalis — manipulation of hidden forces in nature: the properties of stones, planetary influences, the virtues of herbs. Still suspect, but theologically debatable. Certain learned churchmen accept it as part of natural philosophy.
-
Magia daemonalis — any magic involving communication with, invocation of, or cooperation with spirit beings. This is heretical without exception, since every spirit outside God's angels is by definition a demon.
Augustine established, eight hundred years ago, the principle that still holds: it matters not whether the sorcerer claims to work with "angels" or "natural forces" — if he invokes spirit beings, both are in practice "servants of the deceiving rites of demons." Leading theologians are presently developing the concept of the implicit demonic pact — that magic which appears to function without explicit demonic contact nonetheless logically presupposes an implicit agreement with evil powers, since no natural force responds to human formulae of its own accord.
A Dangerous Mind: Thomas of Chobham
It is quietly known within the Order that magi of Stonehenge Tribunal have raised warnings regarding the English theologian Thomas of Chobham, Sub-Dean of Salisbury, who for several decades has argued that incantations producing supernatural effects without sacramental origin presuppose demonic force by definition — regardless of what the text itself states.
He studied in Paris in the 1180s under Peter Cantor — the most influential pastoral theologian of his generation — and carries that Parisian formation still: not to drive heretics to their deaths, but to understand sin in order to cure it. His Summa Confessorum, completed in 1216 and now circulating in over a hundred copies, combines canon law, theology, and practical pastoral wisdom in seven books.
What Stonehenge considers dangerous is this: unlike the active inquisitions against the Cathars and in the Rhineland, Thomas does not hunt and burn — he thinks. He does not dismiss Hermetic magic as mere fraud. He categorises it as an unidentified phenomenon that either has a natural explanation (acceptable) or presupposes an implicit demonic pact (fatal). A magus who claims it is neither faces a burden of proof that may prove exceptionally difficult to discharge.
The Covenant as Curriculum
An inquisitor possessed of theological competence and sufficient Latin who analyses a covenant — its library, laboratory, and members — may perceive a complete intellectual infrastructure for a heterodox magical society:
| Element | Function in the Inquisitor's Eyes |
|---|---|
| Priscillian, Abélard, et al. | Theological and ethical foundation |
| Psellos and similar works | Demonological knowledge base |
| Magic Theory summae and tractati | Practical magical theory |
| Laboratory texts | Operative spell-books — a grimoire library |
This is no longer a curious collection of books. It is a curriculum. In practice, it exposes the accusation of constituting an organised sect — which is, legally speaking, a far graver offence than individual heresy.
Interpreting Hermetic Books
A Hermetic summa or tractatus on Magic Theory contains a cosmological system fundamentally parallel to Christian theology — not fully compatible with it. An inquisitor who can read and genuinely understand what he sees is confronted with:
1. "The Gift" — The Innate Magical Ability
Hermetic theory presupposes that certain individuals are born with an inherent capacity to manipulate magical forces. For an inquisitor, there is exactly one source of supernatural ability outside the sacraments: demonic pact or demonic inheritance. Children born with the Gift bear a disturbing resemblance to notions of witches' offspring. More immediately: if the ability is innate, why has the Church not been informed of these individuals at baptism? Why do they conceal themselves?
2. Vis — Magical Essence as Substance
Hermetic theory describes vis as a concrete, collectable substance possessing magical force. From a theological perspective, this is either:
-
A false claim — no such substance exists, and the one who believes he handles it is deceived by demons
-
A genuine claim — the substance exists, but what is its origin? God's creation contains no such substances outside theological categorisation
In either case, the theory of vis constitutes a parallel cosmology — a doctrine about the fundamental nature of the world with no support in Scripture.
3. The Magic Realm and the Faerie Realm
A book that describes a third and fourth spiritual realm alongside the Divine and the Infernal places its subject outside the entire order of salvation history. There is no cosmological space for a neutral supernatural realm. In the inquisitor's understanding: what is not of God is of the Devil. A theory that postulates neutral magic is either naive or deliberately deceptive.
4. Formulae and Technique Without Divine Reference
Hermetic theory describes the mechanics of magic — Techniques and Forms — without a single reference to God, Christ, or the sacraments as the source of power. An inquisitor reads this as precisely what Augustine warned against: a system that claims human will and knowledge can manipulate creation without God's intervention. At its foundation it is an assertion of independence from God — theologically approaching magic as an alternative soteriological system.
A laboratory text contains specific formulaic descriptions of how to produce an effect: the movement schema of the voice, the precise mental focus, the exact gestures. From an inquisitor's perspective, this is structurally identical to a spell-book in the necromantic tradition. It matters not whether the formula explicitly invokes demons. The structure itself is damning:
-
Precise technical instructions — not meditation or prayer, but an operational protocol
-
Repeatable results — magic that works systematically is more suspicious, not less; prayer works only if God chooses to answer, but formulae that always function can only do so through demonic assistance
-
A codified system — evidence of a learned society sharing knowledge, not a solitary individual's delusion
The Church's Official Stance on Pagan Traditions
Since Gregory the Great in the seventh century, the Church's fundamental strategy has not been to forbid all old customs, but to baptise them. Midsummer is now officially the Feast of St John — the birthday of John the Baptist, son of Mary's kinswoman Elizabeth, and cousin to Our Lord. The bonfires, the dancing, and the festivities persist — but beneath a Christian canopy. The harvest festival has its own ecclesiastical correlate. The Church has long accepted that these customs cannot be extinguished, and has chosen pragmatic coexistence.
The critical document here is the Canon Episcopi — recorded c. 906 by Abbot Regino of Prüm, but held in the Church's eyes to be an ancient ordinance from the Council of Ancyra of 314 — which explicitly demotes belief in nocturnal riding with Diana and other goddesses to the status of superstition: delusion and ignorance rather than actual demon-worship. The pastoral reasoning was deliberate: foolish peasants believe they ride with Freyja, but it is the Devil's illusion, not a genuine encounter with a divinity. This interpretation actually protects many folk practitioners — it denies their rituals any real effect and places them in the category of stultitia (foolishness) rather than hæresis (heresy).
The Three Thresholds of Danger
Tolerated — Ignorance as Protection
If villagers light midsummer bonfires, dance around a pole, hang flowers and crosses in barn beams, and generally do "what has always been done" without naming Freyja explicitly, an inquisitor will likely see nothing worth his time. Inquisitors hunt heretical sects with theological programmes — not ignorant peasants with folk customs. A farmer pouring milk at a standing stone is a bishop's problem. Bishops periodically condemn such practices in pastoral letters; it is a chronic, low-intensity problem, not an inquisitorial matter.
Concerning — Active Invocation of the Divine Name
The situation changes radically if villagers explicitly call upon Freyja by name as a divinity, direct prayers to her, thank her for the harvest, or seek her blessing for the year to come. This moves from folk custom to active idol-worship. Within theology, a pagan deity is either an illusion (at best) or a demon (in the normal case).
Augustine established that the old gods were demons disguised as gods — and this view remains dominant. A god who answers prayers is a demon answering prayers. If Freyja is honoured because the harvests have genuinely been good and the villagers perceive a causal connection, a genuine relationship with a demonic entity has begun to be established.
Dangerous — Organised, Led, and Transmitted
The greatest danger arises when the rites are organised and led. If there is a wise woman, a cunning man, or an aged priestess who leads the rituals, knows the correct forms, and actively preserves a tradition of goddess-worship, the inquisitor no longer sees ignorant peasants — he sees an organised cult.
Why Freyja Is Especially Dangerous
Freyja is no ordinary pagan deity from a Christian theological perspective. She is explicitly associated with:
-
Seiðr — the most prominent practice in the Norse-Germanic magical tradition, associated with divination and the manipulation of will
-
Erotic supernaturalism — as goddess of love, Freyja is associated with uncontrolled sexuality, which in the Church's eyes signals Satanic immorality
-
Death — Freyja receives half the battle-slain in Fólkvangr; her role as a death-goddess carries necromantic associations and encroaches upon Purgatory, Hell, and Heaven as the Church understands them
An inquisitor familiar with literature on the Luciferians will know that they are accused of sexual orgies and the worship of a figure who is partly female — in the bull Vox in Rama, Lucifer is partly described in feminine terms at the sabbath. Freyja-worship with dancing, feasting, and potential sexual liberty on a midsummer night bears a dangerous resemblance to the very accusations being levelled against the Luciferians.
