When people think of early Christianity, they often picture Europe and the Mediterranean world. However, long before modern missionary efforts, Christianity had already reached deep into Asia, taking root in various cultures and kingdoms across the continent. From the Persian Empire to the coasts of China, the faith had a complex and vibrant history long before 1000 AD.
Early Spread: The Eastward Mission
The earliest significant expansion of Christianity into Asia came through the Church of the East, often referred to (sometimes pejoratively) as the Nestorian Church. After the Council of Ephesus in 431 AD, which condemned Nestorius’s teachings, many Christians from the Eastern Roman Empire fled eastward into the Sassanian Persian Empire, where they were more welcomed.
By the 5th and 6th centuries, the Church of the East had become a missionary powerhouse, spreading the gospel far into Asia via trade routes like the Silk Road.
Key Countries and Christian Communities
1. Persia (Modern Iran):
Persia became a major center for Christianity after the Roman Empire declared it illegal for Christians to exist outside the state-approved Church. The Assyrian Church of the East established its patriarchate in Seleucia-Ctesiphon and became influential throughout the Sassanian Empire. Despite periodic persecutions, Christianity endured in Persia for centuries.
2. Central Asia (Sogdiana, Bactria, and beyond):
Christian merchants and monks traveled the Silk Road, establishing communities among the Sogdians, Turks, and other Central Asian peoples. Archaeological evidence, including crosses and inscriptions, shows that Christianity was present in regions like Uzbekistan, Turkmenistan, and even Mongolia before 1000 AD.
3. India:
Christian tradition holds that St. Thomas the Apostle traveled to India and preached there. By the 6th century, a well-established community of Thomas Christians existed along the Malabar Coast (modern Kerala). These Christians had strong ties to the Church of the East and practiced a Syriac liturgy.
4. China:
Christianity first reached China during the Tang Dynasty, with the arrival of the Church of the East missionary Alopenin 635 AD. The Chinese emperor welcomed Alopen and permitted the building of churches. This Christian presence, known as the Jingjiao or “Luminous Religion,” flourished for several generations. A major source of information about this period is the Xi’an Stele (erected in 781 AD), which describes the early history of Christianity in China in both Chinese and Syriac.
5. Armenia and the Caucasus:
While geographically more West Asian, Armenia was the first nation to adopt Christianity as a state religion in 301 AD. Neighboring Georgia and parts of modern Azerbaijan also saw Christian influence during this early period.
Doctrinal Distinctions
Most of the Asian Christian communities before 1000 AD belonged to non-Chalcedonian or dyophysite traditions—particularly the Church of the East. These groups developed independently of the Roman and Byzantine churches and had their own theology, liturgy, and leadership structures.
While they were often labeled “heretical” by Western standards, they played a key role in spreading Christianity to the East, adapting it to local customs and languages along the way.
Challenges and Decline
Despite their reach, Christian communities in Asia faced numerous challenges:
- Political changes (such as the rise of Islam in the 7th century) brought new rulers less sympathetic to Christianity.
- Persecutions under later dynasties and empires led to the destruction of churches and religious texts.
- Isolation from Western Christianity meant these churches often lacked external support and faced pressure to assimilate.
By the end of the first millennium, Christianity in Asia had diminished in visibility, but not disappeared.
Legacy
The influence of early Asian Christianity remains in communities like:
- The Syro-Malabar Church in India
- The Assyrian Church of the East in Iraq and Iran
- Historical memory in China and Central Asia, evidenced by ruins and inscriptions
These early missions planted seeds that would later inspire Catholic and Protestant missions in the modern era—but the first wave of Asian Christianity was indigenous, bold, and deeply embedded in the ancient world.
