Religion of Light (Míngjiào)

← Encyclopedia

Míngjiào — the Religion of Light, the teaching of light — is the name Manichaeism took when it crossed into China. The Chinese characters render Mani’s governing image with a directness no other branch of the religion matched: 明, míng, light or brightness, the radiance of sun and moon set side by side; 教, jiào, teaching or religion. Where Latin and Greek called the faith after its founder, and the Sogdian and Uyghur missionaries carried it under translated divine titles, the Chinese term named the thing itself — the kingdom of light against the kingdom of darkness, and the slow work of drawing the one out of the other. The faith that arrived bearing this name had already traveled the length of Asia. The form it took on the China end of that road — at the Tang court, on the Uyghur steppe, and at last in the hills of Fujian — is a religion in translation, holding a dualist architecture while wearing, in turn, the dress of every tradition it passed through.

The faith that arrived

The man whose name the West kept, Mani, was born early in the third century in Sasanian Mesopotamia, in the Aramaic-speaking baptist world of southern Babylonia, and built from it a deliberately universal church. He drew openly on the materials of three religions already in the field — the Christianity of his Elchasaite upbringing, the Zoroastrian order of the Persian court he served, and the Buddhism he encountered on a journey to the Indian northwest — and presented his own message not as a rival to these but as their completion, the final seal on a single revelation that earlier prophets had each carried in part. The cosmology behind the name — two eternal principles, the catastrophic mixture of light and matter, salvation as the extraction of trapped light and its return to its source — belongs to the founding account of Manichaeism, the Religion of Light, and the long road east to its sibling on Manichaeism in Central Asia and China. What concerns the Chinese name is what became of that architecture once it reached the place that gave the religion its plainest title — and was, in the end, its last refuge.

That a religion built to translate itself should keep, in China, the one element it never translated — the bare fact of light — is the key to its Chinese career. Everywhere else the surfaces changed: in the Roman west the Manichaeans spoke Christian, in Central Asia they spoke Buddhist, rendering the Father of Greatness and the saving emanations into the idiom of buddhas and bodhisattvas and Mani himself into a buddha. But the center held its name. Míngjiào is that center made audible in a fourth language.

Arrival under the Tang

The histories record the religion’s formal appearance at the Tang court late in the seventh century, carried by missionaries out of Central Asia along the trade routes the Sogdian merchants had built. A Persian cleric is said to have presented a Manichaean scripture at court in 694, and within a generation the faith had houses in the capitals. The decisive document of this first phase is the Compendium of the Doctrines and Styles of the Teaching of Mani, the Buddha of Light (摩尼光佛教法儀略), composed at imperial request by a Persian named Fuduo and dated to 731 — an official catechism that set out the religion’s prophets, its clergy, its scriptures, and its discipline in terms the Chinese state could read. It is in this Compendium that the religion’s chosen Chinese face appears: Mani is Móní Guāngfó, Mani the Buddha of Light, slotted into a Buddhist apostolic line and presented as the latest in a sequence that ran through Laozi and the Buddha. The strategy was the same translation-instinct the religion had practiced on every frontier, now aimed at the Tang.

Recognition was uneven and conditional from the start. An edict of 732 distinguished the foreign religion from its missionaries: the doctrine was judged heterodox and Chinese subjects forbidden to practice it, while the resident Central Asian and Persian communities who had brought it were left to their own worship. Manichaeism in China was thus, in its first official definition, a foreigners’ religion tolerated as an embassy of the peoples who held it — a status that tied its fortunes to the standing of those peoples at court. That tie would prove the whole of its Chinese history in miniature: protected while its patrons were useful, exposed the moment they fell.

The Uyghur protection

The patrons who mattered most were the Uyghurs. The ruling house of the Uyghur Khaganate had adopted Manichaeism in the eighth century — the only instance in the history of the world of a Manichaean state — and the Uyghurs were, for a crucial stretch of the eighth and ninth centuries, the Tang dynasty’s indispensable military allies, the cavalry that helped recover the capitals during and after the An Lushan rebellion. Their religion traveled in their wake. Under Uyghur pressure and protection, Manichaean temples — the sources call them by the Buddhist-borrowed term for a monastery — were granted in Luoyang, in Chang’an, and across the cities of the southeast: Jingzhou, Yangzhou, Hongzhou, Yuezhou. An imperial order of 768 authorized a Manichaean temple and gave it the name Dàyún Guāngmíng, Great Cloud of Radiant Light. The faith stood in China not on its own merits but under a foreign umbrella, and everyone — the Manichaean clergy, the Tang bureaucracy, the Uyghur khans — understood the arrangement exactly. Chinese officials wrote of the Manichaeans with the wary courtesy owed to a powerful neighbor’s church.

That umbrella was withdrawn in a single decade. In 840 the Kyrgyz broke the steppe empire of the Uyghurs; the protectors became refugees. Without their patrons the Manichaean communities in China lost their political shelter at the instant the Tang state turned against foreign religions wholesale. The great suppression of the Huichang era — the campaign of the emperor Wuzong that fell on Buddhism, on the Church of the East, and on Zoroastrian fire-temples alike — reached the Manichaeans first. Edicts of 843 ordered the Manichaean clergy seized, their temples and property confiscated, their scriptures and images burned; a chilling notice records that more than seventy Manichaean nuns in the capital were put to death, and the foreign priests dispersed or killed. The organized church in the Chinese heartland was broken in that year, before the broader Huichang persecution of 845 even reached its height. The religion that had stood under the Uyghur shield fell when the shield fell.

The southern survival

It did not vanish. Driven from the capitals, the Religion of Light went south and went quiet, surviving above all in Fujian and the neighboring coast of the southeast — the provinces where the imperial eye reached least and where the maritime trade kept open the channels along which it had first come. There, over the centuries that followed, it underwent the deepest of its translations. Cut off from its Central Asian sources and its foreign clergy, the faith took on the coloring of its surroundings: its vocabulary blurred into that of Buddhism and Taoism, its prophet assimilated to the patterns of local devotion, its meeting into the shape of a folk society. The line between a distinct Manichaeism and the ordinary popular religion of the Fujian countryside grew, by degrees, hard to draw — which was, for a proscribed sect, precisely the point.

To the imperial state the survival registered as a recurring nuisance under a recurring name. Song-dynasty edicts and memorials denounce a heterodox movement of chīcài shìmó — those who eat vegetables and serve the demon — and the phrase fastened on exactly the trait that had always defined the Manichaean Elect: a strict vegetarian discipline kept so as not to wound the light bound in living things. A celebrated memorial of 1120, written in the wake of the Fang La rebellion in the southeast, set down the official portrait of these societies: they assembled by night and dispersed by dawn, ate no meat, worshipped a demon and a white-robed, white-hatted prophet, pooled their goods, and helped one another so that the poor among them never wanted. Read against the Manichaean record, the hostile sketch is a recognizable, if distorting, account of a Manichaean congregation — the night assembly, the vegetarian table, the white robes of the Elect, the communal welfare — refracted through the suspicion of a state that saw in any disciplined secret fellowship the seed of revolt. Later sources name a Religion of Light among the heterodox sects the dynasties watched and at times proscribed, sometimes grouping it with other clandestine salvationist movements. How much continuous Manichaean doctrine survived behind the label, and how much was the state’s own habit of filing every secret society under one heading, is genuinely uncertain.

The popular claim that this underground Religion of Light gave the Ming dynasty its name — that Míng, “bright,” carries the Manichaean light forward into the title of an empire — is a romantic legend, not a finding. It circulates widely, boosted in the modern era by the wuxia fiction of Jin Yong, whose novels make a Ming-cult of the Religion of Light the secret engine of the dynasty’s founding; serious scholarship has largely rejected the etymology. The name of the Ming has its own, unrelated sources. What the legend preserves, accurately, is the memory that a light-religion once ran underground through exactly the regions and centuries from which the dynasty rose.

Cao’an

The trajectory that began in Sasanian Mesopotamia ends in a small stone hall at the eastern foot of Huabiao Hill, in Jinjiang, south of Quanzhou in Fujian: Cao’an, the Thatched Hermitage. The name records its origin as a humble Song-era hut; it was rebuilt in stone in 1339, under the relative toleration of the Yuan. Set into the rock of its rear wall is a seated granite figure — shoulder-length straight hair parted in the middle, a calm full face, robes falling in even vertical folds, hands folded at the lap — carved the same year: Mani as the Buddha of Light, the only sculpted image of the prophet to survive anywhere in the world. To the casual eye it reads as a buddha, and for centuries the people who tended it took it for one; the iconography is Buddhist almost throughout. But the straight hair and the bearded, un-Buddhalike features mark it apart, and a fifteenth-century inscription cut nearby in 1445 names the four attributes of the Manichaean Father of Greatness in Chinese — purity, light, power, wisdom — followed by the title Mani the Buddha of Light. A black-glazed bowl excavated at the site in 1979 carries the words Míngjiào huì, Society of the Religion of Light. The shrine was identified for what it is only in the modern era: read out of a Ming-period gazetteer by Chen Yuan and Paul Pelliot in 1923, located on the ground by Wu Wenliang in 1940. It is generally regarded as the only Manichaean cult site to come down intact from the medieval world, and in 2021 it was inscribed on the UNESCO World Heritage List as a component of Quanzhou, Emporium of the World in Song-Yuan China.

How much living Manichaean doctrine still stood behind the stone by the late imperial period is contested. The local cult that gathered at Cao’an wore Pure Land Buddhist and Daoist dress by the Ming; a sixteenth-century poet who visited saw only Buddhist and Daoist symbols and shows no sign of knowing the place was ever anything else. By then the Religion of Light may have kept the name and the image while losing the memory of what they had named. Yet the continuity of the place itself is not in doubt, and the question of how deep the substratum ran was reopened, sharply, in 2008, when ritual manuals surfaced in nearby Xiapu County — folk liturgies still in use in three villages there for the worship of a figure called Lin Deng, threaded through with Manichaean names, the prophet Mani, the Father of Greatness, the saving light. The Xiapu corpus shows the Religion of Light not as a museum stone but as a living substratum braided into the ritual life of the Fujian coast, deeper and later than the visible record alone would suggest.

The scholarship and the recovered texts

For most of its history the religion was legible only through its enemies — the heresiologists of the Christian and Muslim West, the persecution edicts of the Chinese state — and the Chinese branch above all was known chiefly as a name in a list of proscribed sects. That changed in the twentieth century, and it changed on the eastern road. Three Chinese-language Manichaean texts came out of the sealed library cave at Dunhuang, drawn off by Aurel Stein and Paul Pelliot in the years after 1907: the imperial Compendium of 731, a long sermon known as the Hymn-Scroll (下部讚), and a doctrinal scroll. The doctrinal scroll, the Traité, was the first Chinese Manichaean scripture given to Western scholarship, in the editio princeps of Édouard Chavannes and Paul Pelliot, Un traité manichéen retrouvé en Chine, in the Journal Asiatique of 1911–1913 — a foundational edition still consulted, and one of the few in the field old enough to be freely read. The Compendium itself was first translated by Gustav Haloun and W. B. Henning in Asia Major in 1952–53. The wider documentary recovery — the German Turfan expeditions of 1902–1914, whose tens of thousands of fragments are now cataloged and imaged through the open Digitales Turfan-Archiv of the Berlin-Brandenburg Academy of Sciences — restored the religion’s hymns and prayers in the languages of the road, and let the Chinese material be read in its own continental context.

The standard historical reconstruction of the Chinese church is the work of Samuel N. C. Lieu, whose Manichaeism in the Later Roman Empire and Medieval China (Manchester 1985; rev. Mohr Siebeck 1992) and Manichaeism in Central Asia and China (Brill, 1998) gather the Chinese texts in their original scripts with translation and a working catalog of the whole eastern corpus. The principal living specialist on the Chinese material is Lin Wushu, who has argued the cautious case that by the Ming–Qing period the Fujian practice had absorbed its Manichaean elements into local folk religion behind Buddhist and Daoist surfaces. The Xiapu discovery has generated its own fast-growing literature: Ma Xiaohe and Wang Chuan’s study of the principal Xiapu manual, On the Xiapu Ritual Manual Mani the Buddha of Light (in the open-access journal Religions 9.7, 2018), traces the strong continuity between Tang-period Manichaeism and the later Fujian Religion of Light and shows how its compilers fitted Manichaean content into a Buddhist ritual frame. The granite figure at Cao’an, finally, is documented as a primary monument in the UNESCO inscription of Quanzhou, of which the temple is a component part.

A name outliving its church

The Religion of Light shared the late-antique world of dualist and gnostic currents that ran from Mesopotamia to the Mediterranean, near neighbor to the Mandaean baptists of the same Aramaic homeland and to the broader family of dualism and the search for saving gnosis. It carried that inheritance further than any of them — past the Persian court, across the steppe, down the Silk Road, and into a Chinese folk religion that no longer knew its name. Of the whole vast apparatus Mani built, the seven scriptures, the graded church, the calendar of fasts, what remains intact at the end of the road is a single image: a stone Mani, hands folded, weathered into a hillside above the Fujian coast, where the radiance that gave the religion its plainest name has hardened into granite and the church that carved it has thinned into the prayers of three villages. The name was the last thing to go, because the name was the thing itself — light, cut into the rock, its calm face turned south toward the sea.
