How the Tang Court reacted to this cosmology in their official imperial decrees

The official response of the Tang Court to Alopen’s Christian cosmology and scriptures is remarkably well-preserved. It was permanently memorialized in the official imperial administrative history, the Tang Huiyao (唐會要 / Essential Documents of the Tang), and carved onto the Xi'an Stele.

Emperor Taizong’s reaction was not merely one of polite tolerance; he issued a formal Imperial Edict of Toleration in July 638 CE that legally evaluated and praised Alopen's theological framework.

📜 The Imperial Edict of 638 CE

After spending three years examining Alopen's translated cosmology and texts in the Imperial Library, Taizong issued a decree validating the "Luminous Religion" (Jingjiao). The precise wording of his decree reveals how the court intellectually digested this foreign worldview: 

The Original Classical Decree text:

「道無常名，聖無常體。隨方設教，密濟群生。大秦國大德阿羅本，遠將經像，來獻上京。詳其意旨，玄妙無為。生成立本，濟物利人。宜行天下，所司即於義寧坊建大秦寺一所，度僧二十一人。」

🔍 Unpacking the Court's Assessment

The decree breaks down into a brilliant piece of statecraft that uses imperial pragmatism to validate Alopen’s cosmological claims:

1. "The Way has no constant name; Holy Ones have no constant form." (道無常名，聖無常體)

• The Reaction: Taizong explicitly uses the opening logic of the Dao De Jing ("The Dao that can be spoken of is not the eternal Dao") to accept Alopen’s concept of a formless, uncreated God (Alaha).
• The Meaning: The Tang court concluded that because ultimate truth (Dao) is vast and nameless, it can manifest differently across geographic locations. Alopen’s God was simply viewed as the Western world's manifestation of the ultimate cosmic source. [6]

2. "Its core principles are mysterious, wonderful, and operating through non-action." (詳其意旨，玄妙無為)

• The Reaction: The court evaluated Alopen's Yin-Yang creation cosmology and explicitly labeled it Wuwei (無為)—the pinnacle Daoist concept of "effortless action" or "spontaneous cosmic order."
• The Meaning: Rather than finding the idea of an invisible God organizing the cosmos via a "Primordial Wind" strange, the intellectual elite found it deeply sophisticated. They harmonized it with their own views on how the universe naturally functions without crude physical interference.

3. "It establishes the source of life, benefits all creatures, and is useful to mankind." (生成立本，濟物利人)

• The Reaction: This is the most crucial bureaucratic stamp of approval. The court checked to see if Alopen’s theology would cause political rebellion or social disharmony.
• The Meaning: Because Alopen's translated "Jesus Sutras" heavily emphasized filial piety (honoring parents) and allegiance to the Emperor alongside God, the court ruled that this cosmology actively reinforced state stability. It "established the source of life" (Sheng Cheng Li Ben) in a way that produced good, law-abiding subjects.

🏛️ The Political Aftermath: "The Luminous Bureaucracy"

Taizong's endorsement set off a chain reaction of official court actions that integrated this cosmology into the state fabric for nearly two centuries:

• Imperial Funding: Taizong ordered the immediate construction of a Daqin Monastery (大秦寺) in the prestigious Yining ward of Chang'an, paid for entirely by the state treasury, to house Alopen and 21 ordained monks. 
• The Portrait Honors: Taizong’s successor, Emperor Gaozong, took the patronage further. He elevated Alopen to the rank of "Guardian of the Empire and Lord High Priest" and ordered imperial artisans to paint Taizong’s official imperial portrait onto the walls of the Christian monastery, symbolically intertwining the state's mandate with Alopen’s heavenly cosmology.
• Poetic Endorsements: Later, Emperor Xuanzong (r. 713–756) sent regular gifts of sacred tablets written in his own imperial calligraphy to be hung on the church walls, declaring the "Luminous" worldview to be a source of protective spiritual energy for the royal bloodline. 

⚠️ The Final Political U-Turn (845 CE)

While the Tang court initially loved how well Alopen's cosmology mirrored Daoism, this exact blending eventually backfired. 

In 845 CE, Emperor Wuzong—a fanatical Daoist—decided to purge China of "foreign" influences. In his infamous edict, he stripped Jingjiao of its legal status, declaring that foreign monks were "perverting Chinese customs". Because Alopen's faith had tied its survival entirely to the fickle patronage of the imperial court rather than building roots among the common people, the Luminous Religion vanished from the empire almost overnight when that political favor was withdrawn.
