A Critical History for the Good Work Library

For over fifteen hundred years, nearly everything the West knew about Manichaeism came from people who hated it. Augustine of Hippo, who spent nine years as a Manichaean Hearer before converting to Christianity, wrote more words against his former religion than against any other opponent. The Roman emperors Diocletian, Theodosius, and Justinian issued edicts of escalating severity — from confiscation to exile to death. The Zoroastrian high priest Kartir boasted on rock inscriptions of having persecuted "zandiks" throughout the Sasanian Empire. The word "Manichaean" became, in European languages, a synonym for simplistic dualism — for seeing the world in black and white. The religion itself was dead. Its scriptures were ashes.

Then the sands gave up their dead. In 1902, German archaeologists in the Turfan oasis of Chinese Central Asia began recovering thousands of manuscript fragments in Middle Persian, Parthian, Sogdian, and Old Turkish — the remains of Silk Road communities that had preserved Mani's teaching for centuries. In 1929, seven papyrus codices were unearthed at Medinet Madi in Egypt's Fayyum region — Coptic translations of Manichaean psalms, doctrinal chapters, and homilies, the liturgical voice of a fourth-century Egyptian community. In the 1960s, the smallest codex ever found — a Greek parchment book measuring 3.5 by 4.5 centimetres — was identified in a collection at the University of Cologne. It contained an autobiography of Mani, written by his own disciples. In the 1990s, excavations at Kellis in Egypt's Dakhleh Oasis produced personal letters by ordinary Manichaean believers — laundry lists, family quarrels, theological anxieties — the first direct evidence of what it was like to be a Manichaean in daily life.

The transformation is extraordinary. A religion that was known for a millennium and a half only through the testimony of its executioners now speaks in its own voice — fragmentary, incomplete, but unmistakably its own. This page introduces the tradition for readers encountering it for the first time.

I. The Problem

Manichaeism presents three intertwined problems to the scholar, and each has shaped — and sometimes distorted — every encounter with the tradition.

The first is the problem of evidence. For roughly fifteen centuries, the primary sources for Manichaeism were hostile: Christian heresiologists (Augustine, Titus of Bostra, Ephrem the Syrian), Muslim polemicists, Zoroastrian priests. These sources told scholars what Manichaeism's enemies thought it taught. They did not tell scholars what the Manichaeans themselves said, sang, prayed, or believed. The twentieth-century manuscript discoveries — Turfan, Medinet Madi, the Cologne Mani Codex, Dunhuang, Kellis — revolutionised the field so completely that the study of Manichaeism before and after these discoveries is almost two different disciplines. Samuel Lieu, whose Manichaeism in the Later Roman Empire and Medieval China (1985, revised 1992) is the standard historical survey, built his work on sources that were literally unavailable to scholars a generation earlier. The evidence problem is not solved — vast stretches of Manichaean history remain dark — but it has been transformed from an absence into a puzzle.

The second is the problem of category. What kind of religion is Manichaeism? The Church Fathers said it was a Christian heresy: Mani called himself the Apostle of Jesus Christ and the Paraclete promised in the Gospel of John. The Zoroastrian magi said it was a corruption of Iranian religion: Mani used Zoroastrian divine names and adopted the dualism of light and darkness. The History of Religions School saw it as the supreme expression of Gnosticism: the trapped divine spark, the demiurge, the anti-cosmic contempt for matter. Ferdinand Christian Baur, one of the earliest serious scholars of the tradition, argued that Mani's system was sui generis — a deliberately constructed universal religion that drew from Christianity, Zoroastrianism, and Buddhism but could not be reduced to any of them. The scholarly consensus has increasingly moved toward Baur's position, though the relative weight of the different sources remains debated. Geo Widengren emphasised the Iranian elements. Jason BeDuhn's The Manichaean Body (2000) and Augustine's Manichaean Dilemma (2009–13) have illuminated the Christian matrix. Iain Gardner's The Founder of Manichaeism (2020) placed Mani's Jewish-Christian (Elchasaite) upbringing at the centre of the story. The category problem is not merely academic. How you classify Manichaeism determines which scholars study it, which departments fund it, and which comparative frameworks illuminate or obscure its features.

The third is the problem of scope. Manichaeism was once the most geographically widespread religion on earth. At its height, Manichaean communities existed from Roman Iberia and North Africa in the west to Tang-dynasty China in the east — a span of over ten thousand kilometres, across the entire breadth of the ancient and medieval worlds. No other religion of late antiquity achieved this reach. The Roman Empire, the Sasanian Empire, the Uighur Khaganate, the Tang dynasty, the Abbasid Caliphate — Manichaeism touched them all, and was persecuted by every one of them. The religion survived for over a thousand years, from Mani's mission in the 240s to the last communities in southeastern China in perhaps the sixteenth or seventeenth century. And yet it left almost no physical trace. No Manichaean building survives intact except one — a temple in Fujian province, disguised as a Buddhist shrine. The scope of the religion and the totality of its destruction are both difficult to comprehend.

II. Mani

Mani was born on 14 April 216 CE in the village of Mardinu, near Seleucia-Ctesiphon — the twin capitals of the Parthian Empire, in what is now central Iraq. His father, Patteg (Patik in the Greek sources), was an Iranian of Parthian descent. At the age of four, Patteg brought his son into an Elchasaite community in the district of Dastumaisān — a Jewish-Christian baptismal sect that practiced ritual washing, vegetarianism, and the veneration of celestial beings.

The Elchasaites were part of the same world of Near Eastern baptismal religion that produced the Mandaeans. They wore white garments, practiced repeated immersive baptism, and maintained dietary restrictions rooted in a theology of purity. The Cologne Mani Codex — the tiny Greek autobiography discovered in the 1960s and published by Albert Henrichs and Ludwig Koenen between 1975 and 1982 — provides the most detailed account of Mani's childhood in this community. Before the CMC's discovery, Mani's Elchasaite background was known only from the tenth-century Muslim bibliographer Ibn al-Nadim's Kitāb al-Fihrist. The codex confirmed it and revealed its depth: Mani grew up immersed in a Jewish-Christian ritual world that shaped his vocabulary, his cosmology, and the very categories against which he would ultimately rebel.

At the age of twelve, Mani received his first revelation from a celestial being he called his Twin — syzygos in Greek, taw'am in Syriac. The Twin was not an angel in the conventional sense. It was Mani's divine counterpart — a heavenly self that revealed to him the true structure of reality. At twenty-four, a second and more decisive revelation came. The Twin told Mani what the Elchasaites had wrong: that their rituals of purification were external, that the real purification was internal — the separation of Light from Darkness within the soul and within the cosmos. Mani was to leave the sect, declare his mission, and preach a new, universal religion.

What Mani preached was unprecedented in its ambition. He claimed that every previous prophet — Zoroaster in Persia, the Buddha in India, Jesus in the West — had taught the same essential truth: that the world is a mixture of good and evil, spirit and matter, and that the soul must be freed from its material prison. But each prophet's teaching had been corrupted after his death by followers who misunderstood it, because none of them had written his teaching down. Mani would be different. He would compose canonical scriptures in his own hand, establish a church with a clear hierarchy, and send missionaries across the known world. He was the Apostle of Light, the Paraclete promised by Jesus, the Seal of the Prophets — the final teacher in a universal chain of revelation.

Mani's early mission took him eastward — to India, where he encountered Buddhism and Hinduism — before returning to the Sasanian realm to begin his public preaching. In approximately 242 CE, he gained the patronage of the Sasanian king Shapur I, to whom he dedicated his only work written in Middle Persian, the Shabuhragan. Shapur did not convert — he remained Zoroastrian — but he permitted Mani to preach throughout the empire, and for decades the new religion flourished under royal protection.

The protection did not survive Shapur. Under Bahram I (r. 271–274), pressured by the Zoroastrian high priest Kartir — whose own rock inscriptions at Naqsh-e Rajab boast of his role in persecuting heretics — Mani was arrested, chained, and brought before the king. The accounts differ on the manner of his death. Some sources say he was flayed alive and his skin stuffed with straw; others that he died in prison after twenty-six days of suffering. The most reliable accounts suggest he died in chains, likely in 274 or 277 CE. His death became the religion's central commemorative event — the Festival of the Bema, celebrated annually with an empty throne at its centre, the seat of the absent teacher. Gardner's The Founder of Manichaeism (2020), based on the Jordan Lectures at SOAS London and drawing on the Chester Beatty Kephalaia and the Kellis papyri, is the most recent critical reconstruction of Mani's life.

III. The Two Principles and the Three Times

The foundation of Manichaean theology is absolute dualism — more radical than any other dualism in the history of religion.

The Two Principles

Two eternal, uncreated, co-original substances stand at the base of everything: Light and Darkness. These are not moral categories chosen by a single god (as in Zoroastrian ethical dualism). They are not the result of a divine error or fall (as in most Gnostic systems, where the material world originates from Sophia's transgression). They are ontological realities — fundamental substances of opposite nature that have always existed and always will.

The Kingdom of Light is ruled by the Father of Greatness (identified in Iranian texts with Zurvan, the god of infinite time). It consists of five luminous elements — Mind, Thought, Reflection, Will, and Reasoning — the "dwellings" or "limbs" of the Father. The Kingdom of Light is peaceful, self-sufficient, and infinite. It does not seek anything. It does not need anything.

The Kingdom of Darkness is ruled by the Prince of Darkness (identified in Iranian texts with Ahriman). It consists of five dark elements — Smoke, Fire, Wind, Water, and Darkness. The beings of Darkness are restless, aggressive, and perpetually at war with one another. Darkness is chaotic by nature. It cannot create — it can only devour.

BeDuhn, in a 2020 article on the co-formation of Manichaeism and Zoroastrianism (Entangled Religions, Ruhr-Universität Bochum), argued that the two religions shaped each other in third-century Iran — that Mani's dualism was not simply borrowed from Zoroastrianism but developed in dialogue with it, and that Zoroastrian orthodoxy hardened some of its own positions in response to Mani's challenge. The key difference, as BeDuhn identifies it, is Mani's equation of hylē (matter) with evil. For Zoroastrianism, the material world is Ahura Mazda's good creation, corrupted by Angra Mainyu but fundamentally redeemable. For Manichaeism, the material world is the corruption — a prison made of demonic bodies, designed to entrap the light.

The Three Times

Manichaean cosmology unfolds across three cosmic ages — the Three Times — that describe the origin, the present condition, and the resolution of the cosmic drama.

The First Time — the Separation. Before the world, Light and Darkness existed in absolute separation. The Father of Greatness dwelt in infinite peace. The Prince of Darkness raged in his own realm. Neither knew the other.

The Second Time — the Mixture. The Prince of Darkness looked upward, saw the Light, and desired it. He invaded the boundary of the Kingdom of Light. To defend his realm, the Father of Greatness called forth a series of divine emanations — the Mother of Life, who in turn called forth the Primal Man (Ohrmizd in Iranian texts). The Primal Man descended to do battle with the forces of Darkness. He was defeated. His luminous armour — composed of five Light Elements (Air, Wind, Light, Water, and Fire) — was swallowed by the Archons of Darkness.

This defeat was deliberate. The Light had entered Darkness as a "bait" — a divine strategy in which the Father of Greatness sacrificed a portion of his own substance to entrap Darkness in a process of cosmic digestion from which it could not escape. The divine light was now mixed with matter, and this mixture is the material world. Everything — the earth, the sun, the moon, the stars, the oceans, the human body — is a compound of Light and Darkness. The cosmos exists because the two principles are entangled. It should not exist. It is a wound.

The Father then called forth a Second Evocation — the Friend of the Lights, the Great Builder, and the Living Spirit — who rescued the Primal Man and began constructing the cosmic machinery of salvation. The ten heavens and eight earths were fashioned from the carcasses of defeated demons. The sun and moon were created as "ships of light" — vessels that carry purified light-particles back to the Kingdom of Light. A Third Evocation set the cosmic machinery in motion: the Third Messenger and the Maiden of Light appeared before the archons chained in the firmament, and through their beauty provoked the archons to release the light trapped within their bodies. This episode — the "seduction of the archons" — was a major target of anti-Manichaean polemic, particularly in Augustine's writings.

The Third Time — the Restoration. At the end of history, all Light will have been extracted from matter. A final conflagration will consume the cosmos — a Great Fire burning for 1,468 years. What remains of Darkness will be sealed forever in a bōlos — an eternal prison, a ball of unredeemable matter. The two Kingdoms will be separate again, as they were before the invasion, but now Light knows what Darkness is and will guard against it. This is not salvation in the Christian sense. It is restoration — the healing of a cosmic wound that should never have been inflicted.

IV. The Suffering Jesus and the Column of Glory

Manichaean Christology is one of the most distinctive and least understood aspects of the tradition. Mani distinguished several manifestations of Jesus, each serving a different function in the cosmic drama.

Jesus the Splendour (Jesus the Luminous, Īsā al-Nūr) is a pre-existent cosmic being — not a historical figure but a divine emanation of Light who descended to awaken Adam. In Manichaean mythology, the archons created Adam and Eve as a counter-strategy — a way to concentrate the maximum amount of trapped Light in human bodies and to perpetuate its imprisonment through sexual reproduction. Jesus the Splendour was sent to wake Adam from the sleep of ignorance, to reveal to him his true divine nature, and to warn him against procreation. He is the mythological correlate of the divine Nous — the Mind of Light that awakens the sleeping soul.

Jesus Patibilis — the "Suffering Jesus" — is the most extraordinary concept in Manichaean theology. He is not a person but a cosmic condition: the totality of Light trapped in all matter. The Cruz Lucis (Cross of Light) symbolises this perpetual suffering — Jesus is "crucified" throughout creation, in every tree, every herb, every fruit, every stone. When a plant is cut, when an animal is killed, when fruit is plucked from a branch, Jesus Patibilis suffers. This is why the Elect could not harvest crops, prepare food, or kill any living thing — every such act inflicted suffering on the divine Light trapped in matter. The concept of Jesus Patibilis made the entire material world a site of ongoing crucifixion — a mystic passion that was universal and unending.

The Column of Glory — identified with the Milky Way — was the cosmic mechanism through which liberated Light ascended from the material world to the Kingdom of Light. It functioned as a celestial highway, a pathway of pure light connecting the earth to the divine source. The sun and moon, in Manichaean cosmology, were not merely celestial bodies but active agents in the process of purification — they received the liberated light-particles and transmitted them upward through the Column to the Father of Greatness.

V. The Seal of the Prophets

Mani's most radical claim was not theological but institutional. He claimed to be the Seal of the Prophets — the final teacher in a chain of universal revelation that included Buddha, Zoroaster, and Jesus. Each had received genuine truth. Each had failed — not because the truth was defective, but because the medium of transmission was. Each prophet taught in one language to one people. None wrote his teaching down. After each prophet's death, his followers fragmented and distorted the original message.

Mani would avoid this fate. He would personally compose canonical scriptures, fix the teaching in written form during his own lifetime, and ensure their translation into multiple languages through an organised missionary programme. This was a conscious strategic decision. Mani was not merely a prophet. He was a publisher.

He composed seven canonical works, six in Syriac-Aramaic and one in Middle Persian:

1. The Living Gospel (Evangelion) — his central theological work
2. The Treasure of Life (Thesaurus Vitae) — cosmological and eschatological teachings
3. The Pragmateia — a systematic treatise
4. The Book of Mysteries — on the errors of other religions
5. The Book of Giants — drawing on Second Temple Jewish traditions about the fallen Watchers (Jozef Milik's 1971 discovery of Aramaic fragments of the Book of Giants among the Dead Sea Scrolls at Qumran established a direct literary link between Second Temple Judaism and mature Manichaeism)
6. The Epistles — letters to communities (fragments recovered from Kellis)
7. The Shabuhragan — written in Middle Persian, dedicated to Shapur I; the only work not in Syriac

Nearly all are lost. What survives are fragments, translations, and citations in hostile sources.

Mani was also a painter. He composed an illustrated work called the Arzhang (the "Picture Book") — a visual representation of Manichaean cosmology intended to teach the illiterate and to render abstract theology concrete. The Arzhang is lost, but its existence is attested by multiple sources, and in Islamic tradition Mani is remembered primarily as "Mani the Painter" rather than as a prophet. Thomas W. Arnold proposed that the Manichaean tradition of illustrated bookmaking was the ancestor of Persian miniature painting. Zsuzsanna Gulácsi's work on the surviving fragments of Manichaean illustrated manuscripts from Turfan — Mediaeval Manichaean Book Art (2005) — has demonstrated the extraordinary sophistication of the visual tradition.

The title "Seal of the Prophets" (khātam al-anbiyā') would later be adopted by Islam for Muhammad, with a different theological meaning. For Mani, the expression signified the completion of a chain of revelation that spanned all civilisations. For Islam, it signified absolute finality. The borrowing — or parallel development — is one of the many intersections between Manichaeism and early Islam that remain inadequately explored.

VI. The Church of Light

Mani did not merely preach. He built an institution — a church with a defined hierarchy, a liturgical calendar, a system of ethics, and a clear division of labour between those who extracted the Light and those who sustained the extractors.

The Elect and the Hearers

The Manichaean community was divided into two fundamental classes.

The Elect (electi in Latin, eklektos in Coptic) were the ascetic inner circle — celibate, vegetarian, possessing no property, travelling to preach. They were bound by the Three Seals: the Seal of the Mouth (no meat, no wine, no impure speech), the Seal of the Hands (no violence to anything containing Light — no farming, no cooking, no killing), and the Seal of the Breast (no sexual activity, no marriage). The Elect were, in BeDuhn's analysis, "living refining machines" — their purified bodies liberated the Light trapped in the food they consumed. When an Elect member ate a meal prepared by others, the Light-particles in the vegetables and bread were released through the Elect's spiritual metabolism and ascended toward the Kingdom of Light. When an Elect member died, the Light they had gathered in their lifetime ascended with their soul. They were vessels of cosmic purification.

The Hearers (auditores) were the laity — they could marry, own property, engage in agriculture and trade. Their role was to sustain the Elect: preparing food, providing shelter, giving alms. The Hearers accumulated merit through their service, hoping to be reborn as Elect in a future life. The relationship was symbiotic and, as BeDuhn demonstrated in The Manichaean Body (2000), the daily meal was the focal point of the entire system — the ritual act through which cosmic purification was accomplished, one plate at a time.

The Five Ranks

The Elect were organised into a hierarchy of five ranks, deliberately modelled on the structure of the early Christian church:

1. The Leader (archēgos) — Mani's successor, the supreme head of the Manichaean church. One at a time.
2. Twelve Teachers (magistri) — modelled on the twelve apostles of Jesus.
3. Seventy-two Bishops (episcopi) — modelled on the seventy-two envoys sent by Jesus (Luke 10).
4. Three hundred and sixty Presbyters — elders responsible for local communities.
5. The general body of the Elect — all other members of the ascetic class, both men and women.

This hierarchy was understood as mirroring both the apostolic structure of Christianity and the order of celestial beings in the Kingdom of Light. The church was designed to be portable — a structure that could be replicated anywhere missionaries went, regardless of local culture or language.

VII. The Bema

The highest celebration in the Manichaean liturgical year was the Festival of the Bema — the annual commemoration of Mani's death, celebrated at the vernal equinox after a thirty-day fast. The festival lasted four days and paralleled Christian Easter in both timing and emotional register: mourning for the death of the teacher, followed by the hope of his spiritual presence.

At the centre of the ceremony stood an empty throne — the bema (bēma, a raised platform) — splendidly adorned, symbolising Mani's invisible presence among his followers. The throne probably bore Mani's portrait or a copy of the Arzhang. It was believed that Mani himself returned from the Kingdom of Light during the festival to grant absolution.

The ceremonies included general confession by both Hearers and Elect, absolution for all sins committed in the past year, vigil-keeping, hymn-singing, recitation of canonical texts (including Mani's Seal Letter), sermons, and a quasi-sacramental meal partaken by the Elect. The Bema Psalms archived in this library are the liturgical voice of this celebration — psalms composed for the festival, sung by communities that believed their absent teacher was listening.

Nicholas Sims-Williams, John S. Sheldon, and Gulácsi published A Manichaean Prayer and Confession Book (Brepols, 2022), a major edition of the confessional texts that were central to the Bema and to Manichaean devotional life more broadly.

VIII. The Westward Mission

Within a century of Mani's death, his religion had spread across the Roman Empire with a speed that alarmed both pagan and Christian authorities.

Into Egypt and North Africa

Manichaean missionaries reached Egypt as early as the 240s — during Mani's own lifetime. By the 290s, communities flourished in the Fayyum region. The seven Coptic codices discovered at Medinet Madi in 1929 — the Psalm Book, the Kephalaia, the Homilies — come from these fourth-century Egyptian communities. They were edited by C. R. C. Allberry, Carl Schmidt, and Hans Jakob Polotsky in the 1930s and 1940s, and they gave scholars, for the first time, access to the devotional and liturgical life of ordinary Manichaean believers.

North Africa became the tradition's western heartland. The young Augustine of Hippo (354–430) was a Manichaean Hearer for approximately nine years — from his late teens until his late twenties — before his disillusionment with the tradition and his eventual conversion to Christianity in 387. Augustine's Manichaean period was not a youthful flirtation. He was a serious adherent who recruited friends, debated opponents, and struggled with the tradition's theological problems — particularly the problem of evil, which Manichaeism addressed more directly than any other system he knew.

BeDuhn's Augustine's Manichaean Dilemma (two volumes, 2009 and 2013) reconstructed Augustine's decade-long engagement with Manichaeism and identified Manichaean subtext in nearly every work Augustine wrote between 388 and 401. Johannes van Oort — past president of the International Association of Manichaean Studies — has devoted over twenty-five books to the relationship between Augustine and Manichaeism, arguing that Manichaean influence persisted in Augustine's theology far longer than the bishop of Hippo cared to admit. The irony is considerable: the man who became the most important theologian in Western Christianity — the architect of original sin, of predestination, of the two cities — was shaped in fundamental ways by the religion he spent the rest of his life attacking.

Imperial Persecution

The persecution of Manichaeism in the Roman Empire began before Christianity was even the dominant religion.

Diocletian's edict of 31 March 302 CE — the De Maleficiis et Manichaeis — ordered Manichaean leaders burned alive along with their scriptures, low-status Manichaeans beheaded, and high-status adherents sent to the quarries. The edict described Manichaeism as having "sprung forth like strange and monstrous omens from their native homes among the Persians — a descent group that is our enemy." This language reveals Diocletian's primary concern: Manichaeism was an import from the Sasanian Empire, Rome's geopolitical rival. Religious persecution and imperial security were inseparable.

After Christianity's triumph, the persecution intensified under Christian auspices. Theodosius I stripped Manichaeans of civil rights in 381 and imposed the death penalty on Manichaean monks in 382. Justinian made membership a capital offence in 527, targeting not only active Manichaeans but even former converts who maintained contact with their old communities. By the end of the fifth century, organised Manichaeism had been effectively eliminated from the western Roman Empire. By the sixth, it was gone from the east.

IX. The Eastward Mission — The Silk Road

Mani's ambition was universal, and his missionaries moved east as well as west. The eastward mission — along the Silk Road, through Central Asia, into China — would ultimately produce the tradition's most remarkable political achievement and its longest survival.

The Sogdian Connection

The primary vectors of Manichaean transmission along the Silk Road were Sogdian merchants — Central Asian traders based in the region around Samarkand (modern Uzbekistan) who dominated the caravan routes connecting Iran to China. The Sogdians translated Manichaean texts from Syriac and Middle Persian into Sogdian and facilitated their further translation into Turkic and Chinese. The Manichaean script — derived from Syriac Estrangelo — was used to write texts in at least six languages, a testament to the tradition's multilingual ambition.

The Turfan oasis in the Tarim Basin became a major centre of Manichaean activity. The German Turfan expeditions (1902–1914), led by Albert Grünwedel and Albert von Le Coq, recovered over forty thousand manuscript fragments from the ruins of monasteries and temples along the northern Silk Road. Friedrich Wilhelm Karl Müller's decipherment of the Manichaean script in 1904 opened the fragments to scholarship. The Turfan collection — now in the Berlin State Library — contains texts in more than twenty languages and includes some of the finest examples of medieval Central Asian painting. Mary Boyce's Catalogue of the Iranian Manuscripts in Manichaean Script in the German Turfan Collection (1960) established the scholarly apparatus for working with these materials. Hans-Joachim Klimkeit's Gnosis on the Silk Road (1993) made the Central Asian Manichaean texts accessible to a wider audience for the first time.

X. The Uighur Kingdom — The Only Manichaean State

In 762 CE, something happened that had never happened before and would never happen again: a major state adopted Manichaeism as its official religion.

The Uighur Khagan Bögü was on campaign in China, helping the Tang dynasty suppress the An Lushan Rebellion, when he encountered Manichaean missionaries — likely Sogdian priests embedded with the Tang forces. Four Manichaeans joined his entourage and accompanied him back to the Uighur capital at Ordu-Baliq (Karabalgasun) in Mongolia. Within a year, Bögü had converted and declared Manichaeism the state religion of the Uighur Khaganate.

The Karabalgasun Inscription — a trilingual stele in Old Turkic, Sogdian, and Chinese, erected during the reign of Baoyi Qaghan (r. 808–821) — commemorates this conversion and proudly announces the adoption of Manichaean dietary restrictions, including vegetarianism and abstention from alcohol. The inscription records diplomatic ties with the Tang Empire, the Tibetans, the Abbasid Caliphate, and the Kirghiz — evidence that the Uighur adoption of Manichaeism was not an isolated act of personal piety but a strategic assertion of cultural independence from Tang Chinese influence. The Uighurs chose Manichaeism over Buddhism in part to differentiate themselves from their powerful neighbour.

Under Uighur patronage, Manichaean temples were established in both Tang capitals (Chang'an and Luoyang) and several other Chinese cities. The symbiotic relationship between Uighur political power and Sogdian commercial networks facilitated the religion's spread across Central Asia. For nearly eighty years, Manichaeism enjoyed what it had never achieved anywhere else: state protection, institutional stability, and royal patronage.

The Uighur Khaganate fell in 840, when a rebel minister invited the Yenisei Kirghiz to invade. The Kirghiz sacked Ordu-Baliq. Uighur survivors migrated south to the Tarim Basin and established the kingdom of Qocho (Gaochang) in the Turfan oasis, where Manichaean institutions — temples, clergy, translated scriptures — were transplanted and continued. Manichaeism reached its peak in Qocho around 866 but was gradually displaced by Buddhism. By approximately 1008, Manichaean temples were being converted to Buddhist use. The kingdom of Qocho lasted until c. 1284, but by then Manichaeism was a memory.

XI. The Religion of Light in China

Manichaeism entered China in 694 CE — or possibly earlier, under Emperor Gaozong (r. 650–683) — and underwent a transformation so thorough that it became, in many respects, a different religion.

Chinese Manichaeans adapted their terminology to Buddhist and Daoist vocabulary. The Kingdom of Light became the "Realm of Great Light" (dà míng jiè 大明界). Mani became the "Buddha of Light" (Mónì guāngfó 摩尼光佛). The religion itself was called Mónìjiào or Míngjiào — the "Religion of Light" or the "Bright Religion." In 731, Emperor Xuanzong asked a Manichaean to summarise the tradition's teachings, and the result — the Compendium of the Teachings of Mani, the Buddha of Light — opens with a birth narrative for Mani directly modelled on the life of Siddhartha Gautama. The Chinese Manichaean texts recovered from Dunhuang — discovered in 1900 in the Buddhist scripture cave of the Mogao Grottoes and brought to Europe by Aurel Stein and Paul Pelliot — include the Compendium, the Hymnscroll, and the Traité (the "Sermon on the Light-Nous," published in French by Edouard Chavannes and Pelliot in 1911). These texts reveal a Manichaeism that speaks fluent Buddhist Chinese — a translation so deep that it amounts to a new incarnation of the religion.

After the fall of the Uighur Khaganate in 840, the Tang dynasty turned against Manichaeism, associating it with a fallen foreign power. Manichaean temples were destroyed and monks ordered to return to lay life. But the religion survived underground, particularly in the southern provinces of Fujian and Zhejiang, where it syncretised so thoroughly with local Buddhism that the boundaries dissolved. During the Song dynasty, Manichaean communities participated in popular uprisings — the rebel Fang La, whose massive rebellion in 1120–1121 nearly toppled the Northern Song, drew on Manichaean millennial expectations. During the Ming dynasty (1368–1644), persecution intensified because Míngjiào ("Religion of Light") sounded dangerously close to Míngcháo (the dynasty's own name).

The last identifiable Manichaean communities in China experienced fatal decline around the seventeenth century, retreating into secret practices indistinguishable from heterodox Buddhism. What survives is a single building: the Cao'an temple in Jinjiang, Fujian province — originally built as a Manichaean temple during the Song dynasty, rebuilt in stone during the Yuan dynasty, and now housing a rock-carved statue of Mani donated by a local adherent in 1339. The statue depicts Mani dressed as a Buddha, with a 1445 inscription reading: "Purity, light, great power, wisdom, supreme ultimate truth, Mani the Buddha of Light." It is the only surviving Manichaean structure in the world — a Manichaean temple in Buddhist disguise.

Lieu's recent article "Manichaeism in China: A Century of New Discoveries" (2025) surveys the ongoing reassessment of Chinese Manichaeism in light of archaeological and textual advances.

XII. Under Islam

The Manichaean encounter with Islam was shaped by a single Arabic word: zindīq.

The term — from Middle Persian zandīk, originally denoting a follower of Mani — became the primary accusation levelled against Manichaeans in the Islamic world, and eventually broadened to mean any heretic, dualist, or freethinker. Under the Abbasid Caliph al-Mahdī (r. 775–785), a formal inquisition against zanādīqa was established around 780 CE. Those found guilty who refused to recant were executed. The persecution was sustained and systematic.

Ibn al-Nadīm, writing his Kitāb al-Fihrist in Baghdad around 987 CE, provides one of the most detailed and least hostile accounts of Manichaeism from the Islamic world. He reports personally knowing some three hundred Manichaeans ("Zindiqs") in Baghdad during the time of the Buyid emir Mu'izz al-Dawla (946–967) — but this number had dwindled to fewer than five a quarter-century later. The last leader of the Manichaean community in Iraq fled to Khurasan; the seat of the Manichaean archēgos was eventually forced to Samarkand, in the furthest eastern reaches of the Islamic world.

By the tenth century, organised Manichaeism in the Middle East was effectively extinct. The zindīq accusation lived on — deployed against Sufis, philosophers, and anyone whose ideas smelled of dualism — long after the last actual Manichaeans had died or fled. The word became a weapon of theological policing, detached from its original referent.

XIII. The Death of the Religion

The pattern is consistent across empires and centuries. Every Manichaean community that flourished was eventually destroyed. The agents of destruction differed — Roman emperors, Zoroastrian magi, Chinese mandarins, Islamic inquisitors — but the result was the same. Manichaeism was persecuted more consistently, more widely, and more thoroughly than any other religion in the ancient or medieval world.

Why? Lieu has argued that Manichaeism's universalism was its undoing. A religion that claimed to supersede all other religions — Christianity, Zoroastrianism, Buddhism — was threatening to each of them in a way that a merely local heterodoxy was not. The Manichaean church was also genuinely portable: its hierarchy could be replicated anywhere, its scriptures were translated into every language its missionaries encountered, and its dualistic theology was flexible enough to absorb local divine names and cosmological frameworks. It was, in effect, the first globalised religion — and every empire it touched recognised it as a rival.

By the fourteenth century, Manichaeism as an organised religion had ceased to exist anywhere on earth. What remained were manuscripts buried in sand, texts cached in caves, polemics written by enemies, and the word "Manichaean" itself — surviving in European languages as a term of abuse for anyone who sees the world in black and white. The Bogomils of the Balkans, the Cathars of southern France, and the Albigensians were all accused of being "Manichaean" by their persecutors. Whether any genuine historical chain connects these medieval dualisms to Manichaeism is debated — the supposed transmission from Manichaeism through the Paulicians to the Bogomils to the Cathars is difficult to demonstrate, and "Manichaean" was used as a heresiological label rather than a historical description.

XIV. The Rediscovery

The modern recovery of Manichaeism's own voice is one of the great archaeological dramas of the twentieth century. It unfolded in four acts, each transforming the field.

Act One: Turfan (1902–1914). The German expeditions to Chinese Central Asia recovered the first genuine Manichaean texts ever found — thousands of fragments in Middle Persian, Parthian, Sogdian, and Old Turkish, in a script that was then unknown. Müller's decipherment in 1904 opened a tradition that had been sealed for a millennium. The fragments date primarily from the eighth through tenth centuries and preserve hymns, prayers, doctrinal texts, and fragments of Mani's own canonical works. The Turfan collection revealed the Iranian and Central Asian dimensions of Manichaeism — a religion that had been understood in the West almost exclusively through its Latin and Greek adversaries.

Act Two: Medinet Madi (1929). Seven Coptic papyrus codices of the fourth or fifth century, discovered in an illicit excavation in the Fayyum region of Egypt, gave scholars the religion's liturgical voice for the first time. The Psalm Book — the largest surviving collection of Manichaean devotional poetry in any language — preserves hundreds of psalms, hymns, and prayers sung by the Egyptian communities. Four of the five Manichaean texts in this library come from this discovery. The codices were divided between the Chester Beatty Library in Dublin and the Staatliche Museen in Berlin, a political geography of scholarship that mirrors the tradition's own fragmentation.

Act Three: The Cologne Mani Codex (1960s–1970s). A tiny parchment codex — 3.5 by 4.5 centimetres, the smallest ancient book ever found — identified in a collection at the University of Cologne. Its title: "On the Origin of His Body" (Peri tēs gennēs tou sōmatos autou). It contained a Greek-language biography of Mani written by his own disciples, describing his childhood among the Elchasaites, his visions of the Twin, and his break with the baptismal community. Henrichs and Koenen's publication opened an entirely new direction of research: the Jewish-Christian roots of Manichaeism. Before the CMC, the Elchasaite background was a footnote. After it, the Elchasaite background was the frame.

Act Four: Kellis (1986–1990s). Excavations at the ancient town of Kellis (Ismant el-Kharab) in Egypt's Dakhleh Oasis, led by a Monash University team, produced over two thousand texts from the fourth century — including Manichaean liturgical documents, fragments of Mani's Epistles, and personal letters by Manichaean laypersons. Gardner, the principal editor, has published the texts in the P. Kellis series. Hakon Fiane Teigen's The Manichaean Church in Kellis (Brill, 2021) analyses the social networks that sustained a provincial Manichaean community. For the first time, scholars could see not just the theology but the sociology — what it was like to be a Manichaean in a small Egyptian town, balancing religious obligation with family life, agricultural work, and the pressures of imperial persecution.

XV. Cross-Traditional Connections

Manichaeism is, by design, a syncretic religion — Mani deliberately drew from multiple traditions and presented his teaching as the synthesis and completion of all prior revelation. The cross-traditional connections are not accidental borrowings. They are structural.

Zoroastrianism

The relationship is the deepest and the most contested. Mani adopted Zoroastrian divine names for his celestial hierarchy. The Father of Greatness is identified with Zurvan. The Primal Man is Ohrmizd. The Prince of Darkness is Ahriman. The dualism of Light and Darkness has obvious Iranian resonances. But the critical difference — Mani's anti-cosmic contempt for the material world, which Zoroastrianism emphatically does not share — means that the relationship is one of transformation rather than borrowing. Mani took the Zoroastrian framework and inverted its valuation of the material world. The Zoroastrian magi recognised this as a corruption and reacted accordingly.

Christianity

Mani grew up in a Jewish-Christian community, called himself the Apostle of Jesus Christ, and claimed to be the Paraclete. His church hierarchy was modelled on the apostolic structure. His Christology — with its multiple Jesuses (the Splendour, the Suffering, the Historical, the Judge) — is docetic: Christ did not truly suffer in the flesh, because flesh is Darkness. Augustine's nine-year sojourn as a Manichaean Hearer, and his subsequent career as the most influential Christian theologian in Western history, makes the relationship between Manichaeism and Christianity one of the most consequential in the history of religion. Van Oort has spent a career demonstrating that Manichaean categories persisted in Augustine's thought — in his dualistic framing of the two cities, in his pessimism about the body, in his doctrine of the massa damnata.

Buddhism

Mani travelled to India and encountered Buddhism directly. The division of the Manichaean community into Elect and Hearers structurally parallels the Buddhist sangha's division into monks and laity. The commandments of the Elect — celibacy, vegetarianism, non-violence — resemble Buddhist monastic precepts. The doctrine of transmigration (Hearers reborn as Elect, the wicked reborn in lower forms) has Buddhist resonances. In Chinese Manichaeism, Buddhist terminology was adopted wholesale — Mani became the Buddha of Light, the Kingdom of Light became a Pure Land, and Manichaean temples were indistinguishable from Buddhist ones. Klimkeit explored the Buddhist-Manichaean interaction in both directions, noting that some Central Asian Buddhist confessional texts may have been influenced by Manichaean confessional practices, or vice versa.

Gnosticism and the Mandaeans

Manichaeism shares with the Gnostic systems of late antiquity the basic structure of a divine spark fallen into matter, redeemed through gnosis. But its dualism is more radical — two genuinely co-eternal principles, not a single deity from whom lower beings emanate through error. The Mandaean connection is suggestive: Mani grew up in an Elchasaite community that practiced baptismal rites resembling Mandaean ritual, and Torgny Säve-Söderbergh demonstrated close parallels between Mani's Psalms of Thomas and Mandaean liturgical texts. Whether the Elchasaites and the Mandaeans were related communities, or whether they drew independently on the same baptismal-ritual milieu in southern Mesopotamia, remains unresolved.

Islam

The title "Seal of the Prophets" — Mani's claim of prophetic finality — was later adopted by Islam for Muhammad, with a different theological meaning. The zindīq accusation kept Manichaeism's memory alive in Islamic culture, though in distorted form. Some scholars have explored the possibility of Manichaean influence on early Islamic theology and Sufi mysticism, though direct transmission is difficult to demonstrate. What is clear is that Manichaeism and Islam occupied overlapping conceptual territory — universalist monotheisms with prophetic chains, scriptural canons, and global missionary ambitions — and that the younger tradition defined itself in part against the older one.

XVI. The Manichaean Tradition in This Archive

The Good Work Library holds five Manichaean texts — all from the Coptic and Iranian manuscript traditions, representing the liturgical voice of communities at worship:

Bema Psalms — Eight Coptic psalms from the annual Festival of the Bema, the Manichaean commemoration of Mani's death. Translated from the Chester Beatty collection.

Kephalaia — Excerpts from the doctrinal compendium, specifically Chapter 38 ("Concerning the Three Blows Struck at the Enemy"). From the Medinet Madi discovery. First edited by Ibscher, Schmidt, and Polotsky (1940). Gardner's complete English translation of the Berlin Kephalaia appeared in 1995.

Psalms to Jesus — Nine Coptic devotional psalms addressing the Manichaean Jesus of Light. Translated by C. R. C. Allberry (1938).

Parthian Hymns — A Manichaean apocalyptic hymn in Parthian, the "Hymn on the Second Coming of Jesus." From the Central Asian Silk Road communities — the Iranian voice of a religion that began in Mesopotamia and ended in China.

Miscellaneous Manichaean Texts — Short psalms and fragments from Allberry's 1938 translation, including "Joy Came Over Me."

These five texts represent a fraction of the surviving Manichaean literature. The Psalm Book alone — of which the Psalms to Jesus and the Bema Psalms are small selections — contains hundreds of hymns. The Turfan fragments, the Dunhuang manuscripts, the Kellis papyri, the Chester Beatty Kephalaia — all exist in published translations and deserve archival attention. But what we hold is enough to hear the religion's own voice: not the voice of its enemies, but the voice of communities singing, praying, mourning their prophet, and waiting for the Light to be gathered home.
