The Syrian Christian Churches of Kerala
Christianity reached Britain in the 4th century, carried there by Roman soldiers and missionaries following Constantine's conversion. By that point, according to the tradition that Kerala's Christian community has maintained for nearly two thousand years, the church in Malabar...
Short on time? Let AI summarize it.
The Seven Churches and What They Meant
According to tradition, St. Thomas established seven churches along the Malabar Coast: Maliankara (near Cranganore/Kodungallur), Palayur (near the present-day Guruvayur), Paravur (Kottakavu), Kokkamangalam, Niranam, Chayal (Nilackal - the only inland church, in the hills of what is now Pathanamthitta district), and Kollam.
Each of these locations, the tradition notes, was either a Jewish settlement or a major trading center—or both. This is not coincidental. St. Thomas was an Aramaic-speaking Jew from Galilee arriving in a region where Jewish trading communities were already well established. The presence of the Cochin Jews, documented by their own records in Kerala from early centuries, meant there was both a familiar linguistic and cultural environment and an existing network of relationships into which a Jewish Christian teacher could insert himself. That Cochin Jewish DNA evidence, studied in recent decades, confirms a population present in Kerala from ancient times.
FACT: The Nasrani community's identity has been described as "Indian in culture, Christian in faith, and Syrian in liturgy." Each of these three elements matters separately. The community absorbed Hindu Brahmin social customs, dress, naming conventions, food traditions, and caste practices while maintaining Christian theological content expressed in the East Syriac liturgical tradition. They were, for centuries, indistinguishable from high-caste Hindu families in their social life—and this is precisely why they survived.
The church at Palayur carries a particularly interesting foundation legend. Thomas is said to have arrived at a tank where Brahmin priests were throwing handfuls of water into the air as an offering to the sun god. He challenged them: could they throw the water up so that it stayed suspended without falling? When they could not, he performed the feat himself. The astonished Brahmins converted. Whether the story is historical or theological, it captures something true about how the early Nasrani community positioned itself—as something that could coexist with the existing order, not in opposition to it.
Palayur is today the site of a church that claims to be built on the original foundation. The Arappally Church at Palayur, in Thrissur district, is one of the sites traditionally associated with Thomas's ministry and remains an active congregation.
The Persian Connection: Centuries of Eastern Christianity
Before the Portuguese arrived in 1498, the Syrian Christians of Kerala were in ecclesiastical communion with the Church of the East, based in Persia, also known as the Assyrian Church of the East or the Chaldean Church. Their bishops were appointed by the Patriarch of Seleucia-Ctesiphon. Their liturgy was the East Syriac tradition, using the Anaphora of Addai and Mari—one of the oldest surviving Eucharistic prayers in any Christian tradition, dating possibly to the 3rd century.
FACT: The Anaphora of Addai and Mari, which forms the core of the East Syriac Eucharistic liturgy still used by some Syrian Christian communities in Kerala today, is one of the oldest Eucharistic prayers in continuous liturgical use anywhere in the world. The prayer does not contain an explicit institution narrative—the words of Christ at the Last Supper—a feature unique among Eucharistic prayers that has been the subject of significant theological discussion.
This connection to Persia and the Church of the East is why these Christians are called "Syrian" even though they are Indian. The liturgical and theological tradition they inherited was Syriac in origin, transmitted through the Persian church hierarchy that maintained oversight of Indian Christians for over a millennium. Their ecclesiastical correspondence was in Syriac. Their biblical texts were in Syriac. Their liturgical language was Syriac. These were not imports from Syria but from the ancient Aramaic-speaking Christian world of Mesopotamia and Persia, of which Kerala was a far eastern outpost.
A significant reinforcement of this tradition arrived in 345 CE, when a merchant named Thomas of Cana led a migration of several hundred Christian families—clergy and laity—from the Mesopotamian region to Kerala. The copper plates documenting this migration, known as the Thomas of Cana copper plates, were extant in Kerala until the 17th century. The descendants of these migrants form a distinct community within the broader Nasrani population: the Knanaya Christians, or Southists, who maintain strict endogamy and a tradition of separate ethnic origin from the indigenous Nasranis.
The broader Nasrani community absorbed elements of the caste hierarchy completely. Christians held high social positions—equivalent to Brahmin families in many respects—and participated in the social customs of Kerala's Hindu high-caste communities. They shared naming conventions with Nairs, wore similar dress, celebrated Onam, and shared many practices around birth, marriage, and death. The line between "Christian" and "Hindu" as social categories was, in practice, considerably blurrier than either religious tradition would ideally prefer.
1498: The Portuguese Arrive
Vasco da Gama landed on the Malabar Coast in 1498 with two objectives: spices and Christians. He found both. The Syrian Christians received him with joy—here at last were powerful co-religionists from the West who might help consolidate their position in Kerala's social order. The Portuguese were equally delighted: they had found the legendary Eastern Christians they had been seeking.
The friendship lasted about two decades.
When the Portuguese penetrated further into Kerala and into the churches, they found something they had not expected: a Christian community that was neither subject to Rome nor similar in church traditions to anything in the Western Catholic world. The Nasranis did not follow the Pope. They were in communion with the Patriarch of Persia, whom the Portuguese considered a heretic. Their liturgy was East Syriac, their theology was unfamiliar, their priests were married, and their customs included Hindu observances that the Portuguese missionaries found objectionable.
The Portuguese attempted to bring the Malabar church under Latin Catholic authority through a process that combined persuasion, ecclesiastical pressure, and the implicit threat of Portuguese civil power. When the last Syrian bishop appointed by the Chaldean Patriarch died in 1597, the Portuguese moved quickly to fill the vacuum. Archbishop Aleixo de Menezes, the archbishop of Goa, arrived in Kerala in 1599 with a clear mission: to end the use of Syriac and to make the Syrian Christians Latin Catholics in practice.
The Synod of Diamper: A Liturgy Destroyed
The Synod of Diamper was held at the Church of All Saints in Udayamperoor, near present-day Kochi, from June 20 to 26, 1599. A total of 153 priests and 660 lay representatives attended. The Archdeacon, facing threats to his position, cooperated.
The results were catastrophic for the Nasrani tradition. The synod imposed forced Latinization: the East Syriac liturgy was "purified" of elements the Portuguese deemed heretical; the Chaldean Patriarch was formally condemned; Latin vestments, rituals, and customs replaced the ancient Syriac tradition; clerical celibacy was mandated (ending the tradition of married priests); Syriac manuscripts were ordered to be surrendered and were burned or "corrected." 153 new churches were constructed or reconstructed in Latin style. The Malabar church was downgraded to a diocesan see under the Archdiocese of Goa.
FACT: The Synod of Diamper ordered the destruction of Syriac manuscripts belonging to the Syrian Christian community on the grounds that they contained "heretical" material. How many manuscripts were lost in this process—and what knowledge they contained—cannot be fully known. The Catholic Encyclopedia itself later described the synod as "the only case in which an ancient Eastern rite has been willfully romanized" through "misguided zeal" rather than Roman authority.
The forced Latinization and the destruction of manuscripts were not received in silence. Resistance built over the following decades. By 1641, tensions had crystallized around two figures: Archbishop Francis Garcia, the Portuguese overseer, and Archdeacon Thomas, the head of the indigenous church hierarchy. Then, in 1652, an Eastern bishop named Ahatallah—who had arrived claiming to be the rightful Patriarch of India—was arrested by Portuguese authorities at Mylapore. He disappeared, almost certainly killed. News of his death spread through the Nasrani community. The moment had arrived.
The Coonan Cross Oath: The First Anti-Colonial Protest
On January 3, 1653, Archdeacon Thomas led a mass gathering at the Church of Our Lady in Mattancherry, Kochi. More than five thousand people came. They tied ropes to a large granite cross in the church courtyard—the Coonan Cross, the "bent cross," which bent under the weight of the crowd holding its ropes. Those who could not reach the cross held the ropes. They swore that neither they nor their descendants would ever again submit to the Portuguese bishops or the Jesuit missionaries.
The community split. Of the 116 Syrian Christian churches, 84 eventually returned to Catholic communion under a Carmelite mission that offered to restore East Syriac rites within the Catholic framework. The remaining 32 affiliated with the Syriac Orthodox Church of Antioch when a West Syrian bishop, Mar Gregorios Abdul Jaleel, arrived from Jerusalem in 1665.
This split—between those who maintained communion with Rome and those who aligned with Antioch—was permanent. It generated further splits over subsequent centuries. Today the Nasrani people are divided into multiple denominations: the Syro-Malabar Catholic Church (East Syriac tradition, in communion with Rome), the Malankara Orthodox Syrian Church (West Syriac tradition), the Jacobite Syrian Christian Church (West Syriac tradition, under Antioch), the Mar Thoma Syrian Church (Reformed, influenced by Protestant missionaries), the Chaldean Syrian Church, the Syro-Malankara Catholic Church, and others. Each traces its lineage to the same first-century founding. None of them agrees with the others about what that means for church authority.
FACT: The total St. Thomas Christian population in Kerala today is approximately four million people—roughly 18% of Kerala's population—making Kerala one of the most densely Christian regions in Asia. This community traces a continuous presence on the Malabar Coast for approximately 1,700 years at minimum and, by their own tradition, for 2,000 years.
The Architecture: Three Traditions in One Building
The churches that survive from the pre-Portuguese and Portuguese-influenced periods are among the most architecturally distinctive buildings in Kerala—precisely because they are fusions of three distinct traditions that have no business being in the same building but somehow work.
Kottayam Valiapally (St. Mary's Orthodox Syrian Church, also called the Big Church) and Kottayam Cheriapally (St. Mary's Orthodox Church, the Small Church) are the two essential stops for understanding Syrian Christian architecture. Both are in Kottayam town, within walking distance of each other.
Kottayam Cheriapally, built in 1579 by the Portuguese architect Antony along with craftsmen from the Thekkumkur kingdom, is the clearest example of the synthesis. The facade is Portuguese Baroque: pediments, cornices, and European-style galleries. The walls are over a meter thick, built with granite, limestone, mortar, and timber—a Kerala temple construction technique. The compound wall uses the anappalla (elephant belly) curved style characteristic of ancient Kerala temples. The roof of the portico is supported by ten granite pillars with a large lotus carved from a single piece of granite—a decorative tradition from temple architecture. The niches in the interior walls hold oil lamps, exactly as in a temple. The wooden carvings inside depict biblical scenes in a style continuous with Kerala temple woodwork. The inner sanctuary, called the Madbaha, reflects the Eastern church tradition of a curtained holy of holies, separated from the congregation space called the Haikala.
The Kottayam Valiapally contains the two famous Persian Crosses—large stone crosses with Pahlavi inscriptions that date to the 9th century CE, brought to Kottayam from Cranganore during the Portuguese period. These crosses, with their Syriac-language inscriptions and lotus motifs at the base, are primary evidence of the community's Persian ecclesiastical connection and the antiquity of Christianity on the Malabar Coast.
FACT: The Persian Crosses in the Kottayam Valiapally bear inscriptions in Pahlavi script (the script of Sassanid Persia) and in Syriac, recording grants made to the Christian community by local rulers. The lotus at the base of these crosses—a Hindu sacred symbol—fused with a Christian cross in 9th-century Kerala, is perhaps the most compressed single image of the Nasrani tradition's identity: Indian by culture, Syriac by liturgy, Christian by faith.
The murals of these churches add another layer. Kottayam Cheriapally's interior walls carry paintings depicting scenes from the life of Christ and the Virgin Mary executed in a style that owes as much to Kerala mural painting traditions—the same tradition visible in the murals of the Vadakkumnathan temple in Thrissur—as to any Western religious art convention. At St. Sebastian's Church in Kanjoor, there is a mural depicting the battle between the British and Tipu Sultan—a piece of documentary history painted onto a church wall, in the style of a temple fresco.
The Trail: Thrissur, Kottayam, and the Seven Churches
The Syrian Christian heritage geography is concentrated in central Kerala, with the strongest concentration in the Thrissur and Kottayam districts and significant sites in Ernakulam, Pathanamthitta, and Alappuzha.
Kottayam is the center of Syrian Christian cultural life. The Valiapally and Cheriapally churches are the essential starting points. The Old Seminary in Kottayam, established in 1815 and now known as the CMS College, is one of the oldest Western-style educational institutions in Asia—the Syrian Christians' complex relationship with Protestant missionaries produced, among other things, the first printing press in Kerala and the first institutions for women's education in the region.
The Thrissur district contains some of the sites traditionally associated with the seven churches of Thomas: Palayur (Arappally Church), Paravur, and Kokkamangalam. The Thrissur-Ernakulam belt also contains Udayamperoor, the site of the Synod of Diamper—the church where the forced Latinization occurred is still standing, preserved as a heritage site.
Niranam, near Tiruvalla in the Pathanamthitta district, claims one of the oldest church sites in the tradition. The Niranam church festival and the antiquity of the site are recognized even by communities that dispute other aspects of the Thomas tradition.
The Malayattoor hill shrine in the Ernakulam district is one of the major pilgrimage sites in the tradition—the hill where Thomas is said to have prayed and left a footprint in the rock. The annual Easter pilgrimage to Malayattoor draws hundreds of thousands of pilgrims from across Kerala and beyond.
Experience This With Folk Experience
The Syrian Christian heritage trail is not a museum circuit. These are active, living churches with congregations that have maintained continuous presence for centuries, in some cases on sites that have been Christian places of worship for as long as Christianity has existed anywhere outside the Middle East.

When Thomas arrived in 52 CE, Britain was a distant Roman province where native peoples worshipped at sacred groves and standing stones. The Malabar Coast already had a functioning port city with Jewish merchants and Hindu Brahmin scholars and, within decades, a community of Christians who have not stopped being Christian since. The churches they built over the next two thousand years are still there, still in use, still debating among themselves about who the rightful inheritors of the tradition are. Visit them in that spirit: as a living argument about faith, identity, and what it means for a tradition to survive.
