Saint Thomas Christians

The Saint Thomas Christians, also called Syrian Christians of India, Marthoma Suriyani Nasrani, Malankara Nasrani, or Nasrani Mappila, are an ethno-religious community of Indian Christians in the state of Kerala (Malabar region), who, for the most part, employ the Eastern and Western liturgical rites of Syriac Christianity. They trace their origins to the evangelistic activity of Thomas the Apostle in the 1st century. The Saint Thomas Christians had been historically a part of the hierarchy of the Church of the East but are now divided into several different Eastern Catholic, Oriental Orthodox, Protestant, and independent bodies, each with their own liturgies and traditions. They are Malayalis and their mother tongue is Malayalam. Nasrani or Nazarene is a Syriac term for Christians, who were among the first converts to Christianity in the Near East.

Historically, this community was organised as the Province of India of the Church of the East by Patriarch Timothy I (780–823 AD) in the eighth century, served by bishops and a local dynastic archdeacon. In the 14th century, the Church of the East declined due to persecution by Tamerlane, and Portuguese colonial overtures to bring St Thomas Christians into the Latin Catholic Church, administered by their Padroado system in the 16th century, led to the first of several rifts (schisms) in the community. The attempts of the Portuguese culminated in the Synod of Diamper, formally subjugating them and their whole Archdiocese of Angamaly as a suffragan see to the Archdiocese of Goa, which was under the Portuguese Padroado and celebrated the Roman Rite form of worship. Portuguese oppression provoked a violent resistance among the Thomasine Christians, that took expression in the Coonan Cross Oath protest in 1653. This led to the permanent schism among the Thomas' Christians of India, leading to the formation of Puthenkūr (New allegiance, pronounced Pùttènkūṟ) and Pazhayakūr (Old allegiance, pronounced Paḻayakūṟ) factions. The Pazhayakūr comprise the present day Syro-Malabar Church and Chaldean Syrian Church which continue to employ the original East Syriac Rite (Babylonian Rite /Persian Rite) liturgy. The Puthenkūr group, who resisted the Portuguese, under the leadership of archdeacon Thoma I, organized themselves as the independent Malankara Church, entered into a new communion with the Syriac Orthodox Church of Antioch, and they inherited the West Syriac Rite from the Syriac Orthodox Church, which employs the Liturgy of Saint James, an ancient rite of the Church of Antioch, replacing the old East Syriac Rite liturgy.

The Eastern Catholic faction is in full communion with the Holy See in Rome. This includes the aforementioned Syro-Malabar Church as well as the Syro-Malankara Catholic Church, the latter arising from an Oriental Orthodox faction that entered into communion with Rome in 1930 under Bishop Geevarghese Ivanios (d. 1953). As such the Malankara Catholic Church employs the West Syriac liturgy of the Syriac Orthodox Church, while the Syro-Malabar Church employs the East Syriac liturgy of the historic Church of the East.

The Oriental Orthodox faction includes the Malankara Orthodox Syrian Church and the Jacobite Syrian Christian Church, resulting from a split within the Malankara Church in 1912 over whether the church should be autocephalous or rather under the Syriac Orthodox Patriarch. As such, the Malankara Orthodox Church is an autocephalous Oriental Orthodox Church independent of the Patriarch of Antioch, whereas the Malankara Jacobite Syrian Orthodox Church is an integral part of the Syriac Orthodox Church and is headed by the Syriac Orthodox Patriarch.

The Iraq-based Assyrian Church of the East's archdiocese includes the Chaldean Syrian Church based in Thrissur. They were a minority faction within the Syro-Malabar Church, which split off and joined with the Church of the East Bishop during the 1870s. The Assyrian Church is one of the descendant churches of the Church of the East. Thus it forms the continuation of the traditional church of Saint Thomas Christians in India.

Oriental Protestant denominations include the Mar Thoma Syrian Church and the St. Thomas Evangelical Church of India. The Marthoma Syrian Church were a part of the Malankara Church that went through a reformation movement under Abraham Malpan due to influence of British Anglican missionaries in the 1800s. The Mar Thoma Church employs a reformed variant of the liturgical West Syriac Rite. The St. Thomas Evangelical Church of India is an evangelical faction that split off from the Marthoma Church in 1961.

CSI Syrian Christians are a minority faction of Malankara Syrian Christians, who joined the Anglican Church in 1836, and eventually became part of the Church of South India in 1947, after Indian independence. The C.S.I. is in full communion with the Mar Thoma Syrian Church. By the 20th century, various Syrian Christians joined Pentecostal and other evangelical denominations like the Kerala Brethren, Indian Pentecostal Church of God, Assemblies of God, among others. They are known as Pentecostal Saint Thomas Christians.

Terminology
The Saint Thomas Christians have also been nicknamed such due to their reverence for Saint Thomas the Apostle, who is said to have brought Christianity to India. The name dates back to the period of Portuguese colonisation. They are also known, especially locally, as Nasrani or Nasrani Mappila. The former means Christian; it appears to have been derived from the Hebrew word Netzer or the Aramaic Nasraya from Isaiah 11:1. Nasrani is evolved from the Syriac term for "Christian" that emerges from the Greek word Nazōraioi, Nazarene in English. Mappila is an honorific applied to members of non-Indian faiths and descendants of immigrants from the middle east who had intermarried with the local population, including Muslims (Jonaka Mappila) and Jews (Yuda Mappila). Some Syrian Christians of Travancore continue to attach this honorific title to their names. The Government of India designates members of the community as Syrian Christians, a term originating with the Dutch colonial authority that distinguishes the Saint Thomas Christians, who used Syriac (within East Syriac Rite or West Syriac Rite) as their liturgical language, from newly evangelised Christians who followed the Roman Rite. The terms Syrian or Syriac relate not to their ethnicity but to their historical, religious and liturgical connection to the Church of the East, or East Syriac Church.

Ethnic divisions
Internally the Saint Thomas Christian community is divided into two ethnic groups, the majority Vadakkumbhagar or Northist and the minority Tekkumbhagar or Southist. Saint Thomas Christian tradition traces the origin of these ethno-geographical epithets to the city of Kodungallur, the historic capital of the medieval Chera dynasty. The early converts of Saint Thomas the Apostle and those who later joined the faith in India are believed to have initially resided on the northern side of the city of Kodungallur and for that reason became known as Vadakkumbhagar or Northist.

In either the 4th or 8th century, the Syriac Christian merchant magnate Knai Thoma is noted to have arrived and settled in southern Kodungallur with a cohort of merchants and clergymen. Because they dwelled on the southern side, the descendants of Thoma's migration became known as Tekkumbhagar or Southist. The Southist community is primarily known by the appellation K'nā'nāya (Syriac for Canaanite), an adjectival epithet of Knai Thoma.

The Oxford History of the Christian Church summarizes the division of the community in the following quote: "In time, Jewish Christians of the most exclusive communities descended from settlers who accompanied Knayil Thomma (Kanayi) became known as 'Southists' (Tekkumbha ̄gar)...They distinguished between themselves and 'Northists' (Vatakkumbha ̄gar). The 'Northists', on the other hand, claimed direct descent from the very oldest Christians of the country, those who had been won to Christ by the Apostle Thomas himself. They had already long inhabited northern parts of Kodungallur. They had been there even before various waves of newcomers had arrived from the Babylonian or Mesopotamian provinces of Sassanian Persia."

– Historian of South Asian Studies, Robert E. Frykenberg (2010)

Origin
According to tradition, Thomas the Apostle came to Muziris on the Kerala coast in AD 52 which is in present-day Pattanam, near Kodungallur, Kerala.

The Cochin Jews are known to have existed in Kerala in the 1st century AD, and it was possible for an Aramaic-speaking Jew, such as St. Thomas from Galilee, to make a trip to Kerala then. The earliest known source connecting the Apostle to Northwest India, specifically the Indo-Parthian Kingdom is the Acts of Thomas, likely written in the early 3rd century, perhaps in Edessa.

A number of 3rd and 4th century Roman writers also mention Thomas' trip to India, including Ambrose of Milan, Gregory of Nazianzus, Jerome, and Ephrem the Syrian, while Eusebius of Caesarea records that St. Clement of Alexandria's teacher Pantaenus from Alexandria visited a Christian community in India using the Gospel of Matthew in Hebrew language in the 2nd century.

The tradition of origin of the Christians in Kerala is found in a version of the Songs of Thomas or Thomma Parvam, written in 1601 and believed to be a summary of a larger and older work. Thomas is described as arriving in or around Maliankara and founding Ēḻarappaḷḷikaḷ (Seven great churches): Kodungallur, Kottakavu, Palayoor, Kokkamangalam, Nilackal, Niranam and Kollam. Some other churches, namely Thiruvithamcode Arappally (a "half church"),  Malayattoor and Aruvithura are often called Arappallikal. The Thomma Parvam also narrates the conversion of Jews, natives, and the local King at Kodungallur by St Thomas. It is possible that the Jews who became Christians at that time were absorbed by what became the Nasrani Community in Kerala. The Thomma Parvam further narrates St Thomas's mission in the rest of South India and his martyrdom at Mylapore in present-day Chennai, Tamil Nadu. According to legend, the community began with Thomas's conversion of 32 Brahmin families, namely Pakalomattom, Sankarapuri, Kalli, Kaliyankal, Koikara, Madapoor, Muttodal, Kottakara, Nedumpilly, Palackal, Panakkamattom, Kunnappilly, Vazhappilly, Payyappilly, Maliakkal, Pattamukku, Thaiyil etc. While there is much doubt on the cultural background of early Christians, there is evidence that some members of the St Thomas Christian community observed Brahmin customs in the Middle Ages, such as the wearing of the Upanayana (sacred thread) and having a kudumi. The medieval historian Pius Malekandathil believes these were customs adopted and privileges won during the beginning of the Brahmin dominance of medieval Kerala. He argues that the Syrian Christians in Kerala, integrated with Persian Christian migrant merchants, in the 9th century to become a powerful trading community and were granted the privileges by the local rulers to promote revenue generation and to undermine Buddhist and Jain traders who rivaled the Brahmins for religious and political hegemony in Kerala at the time.

An organized Christian presence in India dates to the arrival of East Syriac settlers and missionaries from Persia, members of what would become the Church of the East, in around the 3rd century. Saint Thomas Christians trace the further growth of their community to the arrival of Jewish-Christians (early East Syriac Christians) from the region of Mesopotamia led by Knāi Thoma (anglicized as Thomas of Cana), which is said to have occurred either in the 4th or 8th century. The subgroup of the Saint Thomas Christians known as the Knanaya or Southists trace their lineage to Thomas of Cana, while the group known as the Northists claim descent from the early Christians evangelized by Thomas the Apostle. The traditional histories of the Thomas Christians note that the immigration of the Knanites reinvigorated the church of India, which was at the moment of their arrival deprived of ecclesial leadership. The arrival of the migrants is also associated with connecting the native Church of St. Thomas with the Syriac Christian tradition of the Church of the East.

During this time period Thomas of Cana received copper plates of socio-economic and religious rights for his relations, his party, and all people of his religion. The granting of these plates is noted to have enhanced the social position of all the ancient Christians of India and secured for them royal protection from the Chera dynasty. The Thomas of Cana copper plates were extant in Kerala until the 17th century after which point they were lost.

Classical period


As the community grew and immigration by East Syriac Christians increased, the connection with the Church of the East, centred in the Persian capital of Seleucia-Ctesiphon, strengthened. From the early 4th century the Patriarch of the Church of the East provided India with clergy, holy texts, and ecclesiastical infrastructure, and around 650 Patriarch Ishoyahb III solidified the Church of the East's jurisdiction over the Saint Thomas Christian community. In the 8th century Patriarch Timothy I organised the community as the Ecclesiastical Province of India, one of the church's Provinces of the Exterior. After this point the Province of India was headed by a metropolitan bishop, dispatched from Persia, the "Metropolitan-Bishop of the Seat of Saint Thomas and the Whole Christian Church of India". His metropolitan see was probably in Cranganore, or (perhaps nominally) in Mylapore, where the shrine of Thomas was located. Under him were a varying number of bishops, as well as a native Archdeacon, who had authority over the clergy and who wielded a great amount of secular power.

Some contact and transmission of knowledge of the Saint Thomas Christians managed to reach the Christian West, even after the rise of the Islamic empires. Byzantine traveller Cosmas Indicopleustes wrote of Syrian Christians he met in India and Sri Lanka in the 6th century. In 883 the English king Alfred the Great reportedly sent a mission and gifts to Saint Thomas' tomb in India. During the Crusades, distorted accounts of the Saint Thomas Christians and the Nestorian Church gave rise to the European legend of Prester John.

The port at Kollam, then known as Quilon, was founded in 825 by Maruvān Sapir Iso, a Persian Christian merchant, with sanction from Ayyanadikal Thiruvadikal, the king of the independent Venad or the State of Quilon, a feudatory under Sthanu Ravi Varma Perumal of the Chera kingdom. Sapir Iso is usually identified either as the East Syriac Christian merchant who led the East Syriac bishops Mar Sabor and Mar Proth to the Christians of Malabar or as the first of those two bishops. This accompanied the second Assyrian migration into the Malabar coast other than the Knanaya migration. The two bishops were instrumental in founding many Christian churches with Syrian liturgy along the Malabar coast and were venerated as Qandishangal (saints) since then by the Thomas Christians. It is believed that Sapir Iso also proposed that the Chera king create a new seaport near Kollam in lieu of his request that he rebuild the almost vanished inland seaport at Kollam (kore-ke-ni) near Backare (Thevalakara), also known as Nelcynda and Tyndis to the Romans and Greeks and as Thondi to the Tamils, which had been without trade for several centuries because the Cheras were overrun by the Pallavas in the 6th century, ending the spice trade from the Malabar coast. The Tharisapalli plates presented to Maruvan Sapor Iso by Ayyanadikal Thiruvadikal granted the Christians the privilege of overseeing foreign trade in the city as well as control over its weights and measures in a move designed to increase Quilon's trade and wealth.

Thus began the Malayalam Era, known as Kollavarsham after the city, indicating the importance of Kollam in the 9th century. The great distances involved and the geopolitical turmoil of the period caused India to be cut off from the church's heartland in Mesopotamia at several points. In the 11th century the province was suppressed by the church entirely, as it had become impossible to reach, but effective relations were restored by 1301. However, following the collapse of the Church of the East's hierarchy in most of Asia later in the 14th century, India was effectively cut off from the church, and formal contact was severed. By the late 15th century India had had no metropolitan for several generations, and the authority traditionally associated with him had been vested in the archdeacon.

MS Vatican Syriac 22 is the oldest known Syriac manuscript copied in India. It is a lectionary of Pauline Epistles copied on AD 1301 (1612 AG) in Kodungallūr (Cranganore, ) at the Church dedicated to Mar Quriaqos.

This manuscript is written in Estrangela script by a very young deacon named Zakharya bar Joseph bar Zakharya who was just 14 at the time of writing. The scribe refers Catholicos-Patriarch of the East Yahballaha III as Yahaballaha the fifth. Johannes P. M. van der Ploeg comments that this may indicate that the patriarch was not well known among the Indian Christians.

In 1490, a delegation from the Saint Thomas Christians visited the Patriarch of the East, Shemon IV, to bring a bishop for India. One among them was Joseph the Indian, who later became famous for his visit to Rome and the account of Malabar in Book VI of Paesi novamente retrovati (1507) by Fracanzano da Montalboddo. The patriarch responded positively to the request of Saint Thomas Christians, and appointed two bishops, Mar Thoma and Mar Yohannan, dispatching them to India. These bishops, and three more (Mar Yahballaha, Mar Dinkha and Mar Yaqov) who followed them in 1503–1504, reaffirmed and strengthened traditional ties between India and the Patriarchate. They were later followed by another bishop, Mar Abraham, who died in 1597. By that time, Christians of the Malabar Coast were facing new challenges, caused by the establishment of Portuguese presence in India.

Portuguese contact
The Saint Thomas Christians first encountered the Portuguese in 1498, during the expedition of Vasco da Gama. At the time the community was in a tenuous position: though thriving in the spice trade and protected by their own militia, the local political sphere was volatile and the Saint Thomas Christians found themselves under pressure from the rajas of Calicut and Cochin and other small kingdoms in the area. The Saint Thomas Christians and the Portuguese newcomers quickly formed an alliance.

The Portuguese had a keen interest in implanting themselves in the spice trade and in spreading their version of Christianity, which had been forged during several centuries of warfare in the Reconquista. Facilitating their goals was the Padroado Real, a series of treaties and decrees in which the Pope conferred upon the Portuguese government certain authority in ecclesiastical matters in the foreign territories they conquered. They set up in Goa, forming a colonial government and a Latin church hierarchy under the Archbishop of Goa, and quickly set to bringing the Saint Thomas Christians under his authority.

The Portuguese subjection of the Saint Thomas Christians was relatively measured at first, but they became more aggressive after 1552, the year of the death of Metropolitan Mar Jacob and of a schism in the Church of the East, which resulted in there being two rival Patriarchs—one of whom entered communion with the Catholic Church. Both patriarchs sent bishops to India, but the Portuguese consistently managed to outmaneuver them, and effectively cut off the Saint Thomas Christians from their hierarchy in 1575, when the Padroado legislated that neither patriarch could send representatives to India without Portuguese approval.

By 1599 the last Metropolitan, Abraham, had died, and the Archbishop of Goa, Aleixo de Menezes, had secured the submission of the young Archdeacon Givargis, the highest remaining representative of the native church hierarchy. The Archbishop convened the Synod of Diamper, which implemented various liturgical and structural reforms in the Indian church. The Synod brought the parishes directly under the Archbishop's purview; anathematised certain "superstitious" social customs characteristic of their Hindu neighbors, including untouchability and a caste hierarchy; and purged the liturgy, the East Syriac Rite, of elements deemed unacceptable according to the Latin protocol. A number of Syriac texts were condemned and ordered burnt, including the Peshitta, the Syriac version of the Bible. Some of the reforms, especially the elimination of caste status, reduced the Saint Thomas Christians' standing with their socially stratified Hindu neighbors. The Synod formally brought the Saint Thomas Christians into the Catholic Church but the actions of the Portuguese over the ensuing years fueled resentment in segments of the community, and ultimately led to open resistance to their power.

Division and defiance
Over the next several decades, tensions seethed between the Portuguese and the remaining native hierarchy, and after 1641 Archdeacon Thomas, the nephew and successor to Archdeacon George of Cross, was often at odds with the Latin prelates. In 1652, the escalating situation was further complicated by the appearance in Mylapore of a mysterious figure named Ahatallah, who claimed to have been sent by the Pope, from the Church of Antioch to serve as "Patriarch of the Whole of India and of China".

Ahatallah made a strong impression on the native clergy, but the Portuguese quickly decided he was an impostor, and put him on a ship bound for Europe by way of Goa. Archdeacon Thomas, desperate for a new ecclesiastical leader to free his people from the Padroado, travelled to Cochin and demanded to meet Ahatallah and examine his credentials. The Portuguese refused, stating the ship had already left for Goa. Ahatallah was never heard from in India again, inspiring false rumours that the Portuguese had murdered him and inflaming anti-Portuguese sentiments even more.

This was the last straw for the Saint Thomas Christians; in 1653, Thomas and community representatives met at the Church of Our Lady in Mattancherry to take bold action. In a great ceremony before a crucifix and lighted candles, they swore a solemn oath that they would never obey Padroado Archbishop Francisco Garcia or the Portuguese again, and that they accepted only the Archdeacon as their shepherd. There are various versions about the wording of oath, one version being that the oath was directed against the Portuguese, another that it was directed against Jesuits, yet another version that it was directed against the authority of Roman Catholic Church. The independent Malankara Church regard the Coonan Cross Oath as the moment their Church regained its independence from the Catholic Church, which they lost during the Synod of Diamper. The Syro Malabar Church deny this argument and regard the Coonan Cross Oath as an explosion against decades long suppression and overbearing attitude of Padroado Latin prelates.

After the events of Coonan Cross Oath three letters were circulated claiming that they had been sent by Ahathalla. One such letter was read at a meeting at Edappally on 5 February 1653. This letter granted to the archdeacon some powers of the archbishop. On hearing it, a vast crowd enthusiastically welcomed Archdeacon Thomas as the governor of their Church and four senior priests were appointed as his counsilors, namely, Anjilimoottil Itty Thommen of Kallisseri, Kuravilangad Parambil Palliveettil Chandy, Kaduthuruthi Kadavil Chandy, Angamali Vengur Giwargis Kathanar. At a further meeting held at Alangat, on 23 May 1653, another letter was read stating that it was from Ahathalla. It instructed the Saint Thomas Christians in the absence of a bishop, twelve of the cattanars (priests) might lay their hands on Thomas, and that this would be adequate as episcopal consecration. The authenticity of these letters is not clear. Some are of the opinion that these letters might be forged by Anjilimoottil Itty Thommen Kathanar who was a skilled Syriac writer. The letters were read with enthusiasm in the churches of the Thomas Christians and Archdeacon Thomas was later proclaimed bishop in a ceremony in which twelve priests laid hands on him, elevating him as Metropolitan with the title Thoma I and he added such ancient titles as 'Metran of All India', 'Gate of India'.

At this point, the Portuguese missionaries attempted reconciliation with Saint Thomas Christians but were not successful. Later, in 1657, Pope Alexander VII sent the Italian priest Joseph Sebastiani as the head of a Carmelite mission of the Propaganda Fide to regain the trust of the dissident St. Thomas Christians. Sebastiani and other Carmelites pressed that the ordination of the archdeacon as metropolitan by the priests in the absence of another bishop was not in accordance with Church laws. They succeeded in convincing a large group of Saint Thomas Christians, including Kadavil Chandy, Palliveettil Chandy and Vengur Giwargis, and Thoma I began to lose his followers. In the meantime, Sebastiani returned to Rome and was consecrated as bishop on 15 December 1659. He reached Kerala again in 1661, being appointed as the Vicar Apostolic of Malabar by the pope. Within a short time period he restored majority of the churches that had been with Thoma I to Catholic Church. However, in 1663, with the conquest of Cochin by the Dutch, the control of the Portuguese on the Malabar coast was lost. The Dutch declared that all the European missionaries had to leave Kerala. Before leaving Kerala, on 1 February 1663, Sebastiani consecrated Palliveettil Chandy was consecrated as the bishop of the Thomas Christians who adhered to Catholic Church. He soon also designated himself as 'Metran of All India' and 'Gate of India'.

Thoma I, meanwhile sent requests to various Oriental Churches to receive canonical consecration as bishop. In 1665, Gregorios Abdal Jaleel, a bishop sent by the Syrian Orthodox Patriarch of Antioch Ignatius ʿAbdulmasīḥ I, arrived in India and the faction under the leadership of Thoma I welcomed him. The bishop was sent in correspondence to the letter sent by Thoma I to the Oriental Orthodox Patriarchate of Antioch. Bishop Abdul Jaleel consecrated Thoma I canonically as a bishop and regularised his episcopal succession. This led to the first lasting formal schism in the Saint Thomas Christian community. Thereafter, the faction affiliated with the Catholic Church under Bishop Palliveettil Chandy came to be known as Pazhayakuttukar (or "Old Allegiance"), and the branch affiliated with Thoma I came to be known as Puthenkūttukār (or "New Allegiance"). These appellations have been somewhat controversial, though, as both parties considered themselves the true heirs to the Saint Thomas tradition, and saw the other party as schismatic. The Pazhayakuttukar or Pazhayakoor faction was also known as Romo-Syrians and organized as the Syrian Catholic Church whereas the Puthenkūttukār or Puthenkoor faction was also known as Jacobite Syrians and organized as the Malankara Syrian Church.

Between 1661 and 1665, the Pazhayakoor faction (Syrian Catholics) claimed 72 of the 116 churches, while Archdeacon Thoma I and the Puthenkoor faction (Malankara Syrians) claimed 32. The remaining 12 churches were shared between the two factions until the late nineteenth century. The Pazhayakūr faction is the body from which the modern Syro-Malabar Church and Chaldean Syrian Church descend. The Puthenkūr faction is the body from which the Jacobite, Orthodox, CSI Syrian Christians, Marthoma, St. Thomas Evangelical Church of India, Syro-Malankara Catholic Church and Malabar Independent Syrian Church originate.

This visit of Gregorios Abdal Jaleel gradually introduced the West Syriac liturgy, customs and script to the Malabar Coast. The visits of prelates from the Syriac Orthodox Church of Antioch continued since then and this led to gradual replacement of the East Syriac Rite liturgy with the West Syriac Rite and the Malankara Church affiliated to the Miaphysite Christology of the Oriental Orthodox Communion. Furthermore, ʿAbdulmasīḥ I sent Maphrian Baselios Yaldo in 1685, along with Bishop Ivanios Hidayattullah who vehemently propagated the West Syriac Rite and solidified the association of the Malankara Church with the Syriac Orthodox Church.

The main body of the Pazhayakoor faction (Syrian Catholics) came to be known as the Syro-Malabar Church. They continued with their East Syriac traditions and stayed within the Catholic Church with Diophysite creed. They had to remain under the foreign Latin bishops, with the only exception of Palliveettil Chandy and Kariattil Ousep. Their Indian East Syriac Catholic hierarchy was restored on 21 December 1923, with Augustine Kandathil as the first Metropolitan and Head.

Failed attempts for reunification and solidification of the schism
A minority within the community of Saint Thomas Christians tried to preserve the use of the East Syriac Rite and re-establishing ties with Patriarchs of the Church of the East, who occasionally sent envoys to India. At the beginning of the 18th century, Bishop Shemʿon of ʿAda (d. c. 1720) and in (c.  1708), Bishop Gabriel of Ardishai (d. c.  1733) arrived to India, sent by the Chaldean Patriarch. Bishop Gabriel temporarily succeeded in reviving the traditionalist community, but was faced with prolonged rivalry, both from West Syriac (Jacobite) and Latin Catholic (Propaganda Fide and Padroado) leadership.

In 1751, Jacobite Maphrian Baselios Shakrallah Qasabgi came to Kerala. He was highly instrumental in replacing the East Syriac Rite with West Syriac Rite among the Puthenkūr faction. He was accompanied by Gregorios Hanna Bakhudaidi, the Jacobite Archbishop of Jerusalem, and Yukhannon (Ivanios) Christophoros of Mosul, whom the Maphrian consecrated as a bishop during his tenure in Kerala. The delegation was sent from the Syriac Orthodox Patriarchate to firmly establish West Syriac Rite among the Puthenkūttukār and regularise the orders of their leader, Thoma V. However, Thoma V died without having reconsecrated, but having himself consecrated his successor as Thoma VI. Thoma VI strongly resisted the efforts of the delegation. Very often the Syriac Orthodox delegates selected their own candidates and ordained them as priests, without consulting Thoma VI. Meanwhile, the Pazhayakūttukār were being increasingly subjugated by their colonial Latin ecclesiastical administrators.

Thoma VI, therefore, initiated efforts to reunify both the factions. However, the Carmelite missionaries working among the Pazhayakūr were reluctant to reciprocate to his efforts fearing that the indigenous bishop would take away their authority and influence over the faction after the proposed reunification of the Saint Thomas Christians was fulfilled. On the other hand, the Syriac Orthodox delegates were extending their influence upon the Puthenkūr, insisting the faction to shift to the West Syriac Rite. Shakrallah, immediately prior to his death, consecrated Kurian Kattumangat as Bishop Abraham Koorilose in 1764. By 1770, Gregorios and Ivanios had Thoma VI reconsecrated as 'Dionysios I'. Thoma VI had to receive all orders of priesthood from the tonsure to the episcopal consecration. Thoma VI received support from Pazhayakūr leaders, who informed him of the ill-treatment and discrimination that they faced from the missionaries. Consequently, two priestly leaders among them: Kariattil Iousep Malpan and Paremmakkal Thoma Kathanar decided to meet the Pope to convey the message of Thoma VI. The Jacobite delegates were soon at odds with Thoma VI and hence in 1772 they raised Abraham Koorilose to the Metropolitan rank at the new Mattancherry Church in Cochin, constructed by Shakrallah. Abraham Koorilose received recognition from the Rajah of Cochin. Kariyattil Iousep, accompanied by Paremmakkal Thoma and two other deacons, made the trip from Kerala in 1778 and he was consecrated as the Archbishop of Cranganore in 1782. However, the efforts drastically failed because of the unexpected death of Iousep while in Goa. Varthamanappusthakam, written by Thoma Kathanar in 1785, provides the detail of this journey until the death of the archbishop. Following this in 1787, representatives from eighty-four Pazhayakūr churches assembled at Angamaly and drew up the Angamāly Padiyōla against the colonial Latin hegemony, declaring their allegiance to the Paremmakkal Thoma and urged for the reinstatement of their native East Syriac hierarchy. Meanwhile, Dionysios I (Thoma VI) managed to imprison his rival, Abraham Koorilose who finally escaped from the states of Travancore and Cochin where the majority of Saint Thomas Christians lived to Anjoor in the territory of the Samuthiri (Zamorin of Calicut). There Koorilose spent his days in prayer and meditation in a hut. A few relatives and friends joined him there. This group, originally known as the Thozhiyur Church, was later confirmed as an independent Syrian Church in Malabar by the Madras High Court, through a verdict in 1862. Subsequently, they took the name Malabar Independent Syrian Church.

British period
In 1795, the kings of Travancore and Cochin entered into tributary alliance with the British East Indian Company to repel the attacks from Tipu Sultan. The states soon became client regimes of the company: both were forced to disband their military. The political order of the states also began to collapse. Saint Thomas Christians were hit hard by the loss of their privileged military role, their kalari network was dissolved and many families lost their livelihood. The trading class, as well as the office bearers, also suffered the setback and many Europeans who visited the states between 1801 and 1820 noted the poor and depressed condition of Saint Thomas Christians of the Puthenkuttukar. Some partisan fund allocation for the churches by the British officials triggered a breakdown in the relationship between Saint Thomas Christians and prominent Hindu castes, at least temporarily. In 1815, the British Resident, Colonel John Munro, founded a seminary in Kottayam, for the theological education of Jacobite Christian priests and invited the Anglican missionaries to teach there. This could be regarded as the beginning of the relationship between the CMS (Church Mission Society) and the Saint Thomas Christians of the Puthenkuttukar.

Further divisions
As a protest against the interference of the Anglican Church in the affairs of the Puthenkūttukār faction of the Saint Thomas Christians, the Metropolitan, Cheppad Dionysios, convened a Synod at Mavelikara on 16 January 1836. There it was declared that Malankara Church would be subject to the Syrian traditions and Patriarch of Antioch. The declaration resulted in the separation of the CMS missionaries from the communion with the Malankara Church. Cheppad Dionysios, abdicated during the tenure of an Antiochian prelate named Yuyakim Koorilose (arrived c. 1846, d. c. 1874). During his stay in among the Puthenkoor, Koorilose completed the transition to West Syriac ritual practices. However, a minority from the Malankara Church, who were in favour of the Reformed ideologies of the missionaries, stood along with them and joined the Anglican Church. These Saint Thomas Anglicans, were the first Reformed group to emerge from the Saint Thomas Christian community and they worked along with the missionaries in their evangelical, educational and reformative activities. By 1879, the Diocese of Travancore and Cochin of the Church of England was established in Kottayam. On 27 September 1947, the Anglican dioceses in South India, merged with other Protestant churches in the region and formed the Church of South India (CSI); an independent United Church in full communion with all its predecessor denominations. Since then, Anglican Syrian Christians have been members of the Church of South India and also came to be known as CSI Syrian Christians. In 1860, tired of their Latin subjugation, the Pazhayakūttukar sent a delegation headed by Antony Thondanatt (d. c. 1900) to Mosul to make a plea to the Chaldean Catholic patriarch to consecrate a bishop of their own rite for them. In response, Patriarch Joseph VI Audo consecrated Thomas Rokos, titular archbishop of Basra, and dispatched him to visit the alienated Malabar Christian flock in 1861. However, the mission failed due to the protests of the apostolic delegate at Mosul, Henri Amanton, and the vicar apostolic of Verapoly. As a result, the Pope forced the Patriarch to call back the bishop. There was yet another incident on 5 June 1864. Patriarch Joseph VI consecrated Elias Mellus, bishop of Aqra, and sent him to India. But this effort too was met with the same fate as before and Mellus was called back in 1882. Meanwhile, in 1862, an attempt was made to reestablish direct ties between traditionalist Christian communities in India and the Assyrian Patriarch Shimun XVIII consecrated the aforementioned Thondanatt as Abdisho, the Metropolitan of India, but his task proved to be very difficult and challenging. He intensified his activity after 1882, fulfilling the aspirations of local Christians of the East Syriac Rite for the full re-establishment of traditional ecclesiastical structure. Until his death in 1900, he partially succeeded in organizing the local church, that was named the Chaldean Syrian Church. After his death, local Christians appealed to Shimun XIX, Patriarch of the Assyrian Church of the East in Qochanis who was forthcoming, and in December 1907 consecrated Abimalek Timotheus as metropolitan bishop for India. He reached his diocese in February 1908, and took over the administration. He organized ecclesiastical structures, and continued with revitalisation of the East Syriac Rite.

By June 1875, there were two factions among the Malankara Church: Conservative Party and Reform Party. Mathews Athanasius was the Malankara Metropolitan approved by the Governments of Travancore and of Cochin and he was supportive to the reforming of the Jacobite church with evangelistic ideologies. Hence the group with Mathews Athanasius was known as "Reform Party" The conservative faction, under the leadership of Metropolitan Pulikkottil Joseph Dionysious II, opposed the attempts to do away with the age-old traditions of the church, which resulted in a stir in the community. Being invited by this faction, the Antiochene Patriarch Ignatius Peter III arrived in Kerala. In June 1876, at the synod of Mulanthuruthy, presided over by the Patriarch, the Syrian faction formally came under the Antiochene Patriarchate. The synod condemned Mathews Athanasius for abstaining from it, but his followers stayed firm with him. His successor Thomas Athanasius and the bishop's faction lost the lawsuit to the Patriarchal faction in the Royal Court of Travancore on 12 July 1889. Nonetheless, the Reform Party continued as an independent Church and thereafter a series of suits arose on the rights over churches and associated properties. Later they chose the name Mar Thoma Syrian Church.

In 1911, Patriarch Ignatius ʿAbdullāh II excommunicated Vattasseril Geevarghese Dionysios (Dionysios VI), the Malankara Metropolitan, due to dispute of authority over the properties of the Malankara Church. This led to the division of the Church into two groups, with one group accepting the supreme authority of the patriarch and the other supporting Dionysios VI. The group led by Dionysios VI invited Patriarch Ignatius ʿAbdulmasīḥ II, who was deposed from Patriarchate by the Turkish authorities. In 1912, ʿAbdulmasīḥ II arrived in India and he consecrated Baselios Paulose I (d. c. 1914) as Maphrian (Syriac Orthodox Catholicos). This was not recognised by the Syriac Orthodox Church. Previously ʿAbdulmasīḥ II himself had declined the request for the installation of a Maphrianate for India in 1902 during his patriarchate. The independent group under Metropolitan Dionysios VI, known as the 'Metropolitan's Party', started endorsing the claims for autocephaly. The other group, known as the 'Patriarch's Party', remained loyal to the Patriarch and was led by Coorilos Paulose, succeeded by Athanasius Paulose. The two sides filed a series of lawsuits in the civil courts and some parallel attempts to reconcile both the parties also took place. In 1958, bishops of both the parties sealed their reconciliation and signed a treaty which in turn recognised the autonomy of reunited factions, with its own synod of bishops under the presidency of the Catholicos. The verdict of the Supreme Court of India in 1958, legitimizing the autonomy of Kerala church, was instrumental in this formal reconciliation between the two sides. In 1964, Patriarch Ignatius Yaʿqub III consecrated Baselios Augen I (d. c. 1975) as the Catholicos. Nonetheless, in 1975, both the parties split again with the decision of the Universal Syrian Synod, held in Damascus, to depose the Catholicos in Kerala and Baselios Paulose II was consecrated as the Catholicos for the 'Patriarch faction'. Today the West Syriac Oriental Orthodox community in India is divided between the Malankara Orthodox Syrian Church (an autocephalous Oriental Orthodox church) and the Jacobite Syrian Christian Church (an autonomous church under the Antiochene Patriarchate).

In 1930, a section of the Malankara Church under the leadership of Archbishop Geevarghese Ivanios and Jacob Theophilos left the Malankara Orthodox Syrian Church and came into communion with the Catholic Church. They are known as Syro-Malankara Catholic Church. On 11 June 1932, Trivandrum was recognised as a Metropolitan See sui juris, with Thiruvalla as its suffragan. On 10 February 2005, the church was raised to the status of a Major archiepiscopal church. The canonical installation of Cyril Baselios as the first Major Archbishop took place on 14 May 2005 and simultaneously the title 'Catholicos' was legitimized. The St. Ephrem Ecumenical Research Institute (SEERI), inaugurated on 14 September 1985, comes under the Syro-Malankara Catholic Archbishop of Thiruvalla.

In 1961, there was a split in the Malankara Mar Thoma Syrian Church which resulted in the formation of St. Thomas Evangelical Church of India.

Pentecostalism began to spread among Saint Thomas Christians from 1911, due to American missionary work. The first Syrian Pentecostals came from Kerala Brethren, who were in turn mostly ex-Marthomites. As the movement gained momentum, groups of people from all traditional St. Thomas Christian denominations became part of various emerging Pentecostal and evangelical fellowships. Pentecostals from Syrian Christian background spearheaded the movement in Kerala and to a lesser extent in India, by providing the necessary leadership for establishing denominations like Indian Pentecostal Church of God, Assemblies of God in India, Church of God (Full Gospel) in India, The Pentecostal Mission and many other Neo-charismatic churches. The Syro-Malabar Church too has a very active Charismatic ministry, operated through establishments such as the Divine Retreat Centre, Muringoor.

Involvement in politics
Participation based on caste and community divisions and sympathies has been a feature of politics in the present day state of Kerala and its predecessor entities. Until the mid-20th century the primary cause of the divisions between the various communities was competition for rights and resources.

Like other communities, Saint Thomas Christians have been involved in regional politics on a community basis. In 1888, Travancore became the first princely state in India to establish a Legislative Council, which was reformed as the Sree Moolam Popular Assembly in 1904. A few Saint Thomas Christian leaders were elected to the Legislative Council but there was resentment that their share of the available seats was proportionately less than that of other prominent castes. This resentment led to a series of campaigns for equal representation both in the legislature and in government positions. Jatiaikya Sangham, an organization formed with an objective of reuniting the Pazhayakoor and Puthenkoor communities, came up with the idea of a newspaper that resulted in the establishment of Nasrani Deepika by Nidhirikkal Manikkathanar in 1887. Newspapers such as the Nasrani Deepika and Malayala Manorama disseminated their grievances.

In 1918, Saint Thomas Christians formed the League for Equal Civic Rights, which sought the opening of all branches of government service to Christians, Muslims and avarna Hindus, as well as an end to the practice of untouchability. Their demands were partially met in 1922 when the Revenue Department was separated from the Devaswom, a semi-government organization that managed the Hindu temples, thus removing the restriction on non-Hindus and avarnas in the executive service. In the 1920s, Saint Thomas Christian leaders such as George Joseph were advised by Mahatma Gandhi to detach from Vaikom Satyagraha, an agitation for the temple entry rights of avarna Hindus, as he considered the issue to be one of concern to Hindus alone. Titus Theverthundiyil was one of the 78 marchers selected by Gandhi to take part in the 1930 Dandi March, to break the British salt monopoly.

With the institution in 1932 of a bicameral legislature in Travancore, four Saint Thomas Christians found a place in among the 24 seats of the lower house, but not comparable with other forward castes. The 1931 census recorded over 31 per cent of the population as being Christian, compared to around 4 per cent in 1820. Some restrictions were imposed on Saint Thomas Christian parishes to start new schools and later on the Diwan attempted to take over the schools owned by the community. There followed a period of fierce confrontation between the Diwan and Saint Thomas Christians—many leaders were arrested, prominent news papers were banned and large banks owned by the community members were liquidated. In 1937, general elections were held and Joint Political Congress played a significant role to attain much better representation for allied communities. T.M. Varghese was elected as the Deputy President of the Assembly where C. P. Ramaswami Iyer was the ex officio President. On the collapse of Joint Political Congress due to internal conflicts, Saint Thomas Christian leaders allied with Nairs in a common platform- Travancore State Congress where they fought together for responsible government and also to oust Iyer. Abraham Marthoma mobilised Syrian Christians against the divan's move not to unite with free India. In the three-member Cabinet of Travancore formed after the first general elections in 1948, Varghese was a Cabinet Minister. However the first Saint Thomas Christian to become a minister in the central government of India was Padma Vibhushan John Mathai, who served as India's first Railway Minister and subsequently as India's Finance Minister, taking office shortly after the presentation of India's first Budget, in 1948.

Though the government initiated the legislation process for reforming the land and the education sectors, these were considered as infringements over the rights by the school managements and landowners, who were predominantly Saint Thomas Christians and Nairs. The disagreements of the Saint Thomas Christians further widened and they allied with Nair Service Society to mobilize against the government, which culminated in a violent struggle, called the Liberation Struggle, in 1958. The Communist government was dismissed on 31 July 1959 and the President's rule was imposed in the state under Article 356 of the Constitution of India.

Socio-cultural and religious identity
St. Thomas Christians are a distinct community, both in terms of culture and religion. Though their liturgy and theology remained that of East-Syrian Christians of Persia, their life-style customs and traditions were basically Indian. It is oft-quoted: "Nazranis are Indian in culture, Christian in faith and Syrian in liturgy".

At present, Saint Thomas Christians represent a multi-cultural group. Their culture is largely derived from East Syriac, West Syriac, Hindu, Jewish, and Latin liturgical influences, blended with local customs and later elements derived from indigenous Indian and European colonial contacts. Their language is Malayalam, the language of Kerala, and Syriac is used for liturgical purposes.

Jewish influence has been observed in Malabar Nasrani liturgy and traditions. The community maintained some of the original Jewish practices, such as covering their heads while in worship. Their celebration of Holy Liturgy (Holy Mass) was and still is called the Qurbana, which is derived from the Aramaic term Qurbana (ܩܘܪܒܢܐ), meaning "sacrifice". Nasrani Qurbana used to be held in Syriac till the early 20th century.

Saint Thomas Christians typically followed the social customs of their Hindu neighbours, and the vestiges of Hindu symbolism could be seen in their devotional practices. Social sins like Untouchability entered their practices and the Synod of Diamper abolished it. The sacraments related to birth, marriage, pregnancy, death etc. also adapted nuances from Hindu religious practices. Even today, tying Minnu, a Hindu symbol of marriage is the most important rite in the Christian marriages too. In 1519, a Portuguese traveler Duarte Barbosa on his visit to Malabar commented on the practice of Saint Thomas Christian priests using Kudumi similar to that of Hindus, in his manuscript "Book of Duarte Barbosa".

In the social stratification of medieval Malabar, Saint Thomas Christians succeeded in relating their social status with that of upper-caste Hindus on account of their numerical strength and influence and observance of many Brahmin and upper caste customs. In the 13th and 14th centuries, many Saint Thomas Christians were involved in the pepper trade for the local rulers and many were appointed as port revenue officers. The local rulers rewarded them with grants of land and many other privileges. With growing numerical strength, a large number of Saint Thomas Christians settled in the inland pepper-growing regions. They had the right to recruit and train soldiers and Christian trainers were given with the honorary title "Panikkar" like their Nair counterparts. They were also entitled with the privilege to collect the tax, and the tax-collectors were honored with the title "Tharakan".

Like Brahmins they had the right to sit before the Kings and also to ride on horse or elephant, like the royals. They were protectors of seventeen underprivileged castes and communities and hence they were called Lords of Seventeen Castes. They did not allow the lower-castes to join their community for fear that it could imperil their upper-caste status. But this regal period ended when the community fell under the power of the Rajas of Cochin and Travancore. They owned a large number of Kalaripayattu training centers and the Rajas of Travancore and Cochin, including the renowned Marthanda Varma, recruited trained Christian warriors to defend their kingdom.

The upper-caste Hindus and Saint Thomas Christians took part in one another's festival celebrations and in some places in Kerala, the Hindu Temples and Saint Thomas Christian Churches were built on adjoining sites by the Hindu Kings. Until the 19th century, Saint Thomas Christians had the right of access to Hindu temples and some leading Saint Thomas Christians held the status of sponsors at Hindu shrines and temple festivals. But in the 19th century, Saint Thomas Christian integration with the Hindu caste system was disrupted: their clean-caste status was questioned in some localities and they were denied access to many Hindu temples. They tried to retaliate by denouncing Hindu festivals as heathen idolatry. Clashes between upper-caste Hindus and Saint Thomas Christians occurred from the late 1880s, especially when festivals coincided. Internecine violence among various Saint Thomas Christian denominations aggravated their problems.

Existing traditions, music, rituals and social life
Saint Thomas Christians still retain many of their ancient traditions and rituals, both in their social and religious life. Saint Thomas Christian services have many unique characteristics compared to others. Prior to the 1970s, the Nasrani Qurbana was completely sung in Syriac. Many of the tunes of the Saint Thomas Christian worship in Kerala, especially those in the East Syriac tradition, are remnants of ancient Syriac tunes of antiquity.


 * Saint Thomas Christians observe Holy Thursday with high reverence. This day is referred to as Pesaha, a Malayalam word derived from the Aramaic or Hebrew word for Passover—Pasha or Pesah—commemorating the Last Supper of Jesus Christ during Passover in Jerusalem. The tradition of consuming Pesaha Appam after the church service is observed by the entire community under the leadership of the head of the family. Special long services followed by the Holy Qurbana are conducted during the Pesaha eve in the churches.
 * The community observes Lent, locally called Anpathu noyambu (the fifty days' fast) or the Valiya noyambu (Sawma Rabba, the Great Fast), from Clean Monday or the preceding Sunday (called the Pētūrttà (meaning "looking back"), this is the original practice and it still prevails among the Chaldean Syrian Church) to the day before Easter, abjuring all meat, fish and egg. They also traditionally observe the 25 days' fast which ends on the day of Christmas.
 * Generally, footwear is removed before entering the church and women cover their heads during worship.
 * On the day of Palm Sunday known as Oshana or Hoshana Sunday, flowers are strewn about the sanctuary, loaned from the Hindu ritual of offering flowers, and the crowd shouts "Oshana" (ܐܘܿܫܲܥܢܵܐ (ʾōshaʿnā) meaning 'save, rescue, savior' in Aramaic). Then palm leaves are blessed and distributed after the Qurbana (Holy Mass).
 * The celebration of Holy Liturgy (Holy Mass) is commonly called the Holy Qurbana, regardless of whether it is the East Syriac Holy Qurbana or West Syriac Holy Qurobo. The Holy Qurbana is mostly conducted and prayers recited in Malayalam. However, significant parts of the Holy Qurbana are sung in Syriac. During the 20th century, the 'Qurbana-kramam' i.e. the 'book containing the order of worship', was translated into English, for the benefit of worshipers who lived outside Kerala, and did not know to read or write Malayalam.
 * Saint Thomas Christians use East Syriac term Māràn Īshoʿ Mîshîħa (Jesus' name in Aramaic ) to denote Jesus Christ.
 * The Saint Thomas Christians, particularly of the West Syriac Rite, pray the canonical hours of the Shehimo seven times a day.
 * Another surviving tradition is the use of muthukoda (ornamental umbrella) for church celebrations, marriages and other festivals. Traditional drums, arch decorations and ornamental umbrellas and Panchavadyam are part of the church celebrations. Their use has become popular all over Kerala.
 * The sacraments and ceremonies of Saint Thomas Christians related to house building, birth and marriage have close similarity with those of Hindus in Kerala. The sacrament of Death express Christian canonical themes very distantly and the influence of Hindu culture is quite noticeable. Much stress is given to ideas concerning eternal life after death and the anticipation of Christ's final judgment.
 * Saint Thomas Christians do not marry close relatives. The rule is that the bride and groom must not be related for at least five or seven generations.
 * Saint Thomas Christians generally prefer arranged marriages and the prospective partners see each other in the Pennukanal (Bride Viewing) ceremony at bride's home.
 * Saint Thomas Christian marriage customs are uniquely different from Western Christian marriage and local Hindu marriage customs. For example, engagement and marriage are usually performed together in the same service. Unlike Western Christian traditions, there is no direct ring exchange between groom and bride during engagement, rather it is offered and mediated by the Kathanar who represents Jesus Christ, symbolizing that it is God who brings the couple together into marriage. The tying of the Minnu (Mangalasutra) and the giving of the "Manthrakodi" or "Pudava" to the bride are the major wedding rituals loaned from Hinduism. Manthrakodi, a silk saree with a golden zari border is blessed by the priest and is placed by the bridegroom by covering the hair of the bride, it symbolises the "Pudavakodukkal" ceremony of the Nambudiri Brahmins, where similarly the bridegroom places a silk cloth by covering the head of the bride.
 * Saint Thomas Christians widely use Nilavilakku (a lighted metal lamp), Kindi, Kalasha and other bronze articles in their houses and churches.
 * The night before the marriage a ceremony known as "Madhuram Veppu", is conducted. The ceremony is conducted separately for the bride and the bridegroom. It includes serving the bride and the bridegroom sweets by the maternal uncle. It has been loaned from the Knānāya (Southist) community's tradition called as "Chantham Charthal", where similarly the couple are served sweets. Chantham Charthal for the bride includes applying of Henna, Sandal and turmeric over the palms and legs as a symbolism of purity. The face of the bridegroom is cleanly shaved as a ritual. All the traditions are accompanied by the Panan Pattu performed by the Panan caste, who sings the grants and privileges given to the Syrian Christians.
 * The traditional dress of a Saint Thomas Christian woman is the Chatta and Mundu, a seamless white garment, which is now limited to older female adherents. Following the general trend, the Sari and Churidar have become predominant among the younger generations.
 * Many artforms like Margamkali (an ancient dance form performed in a circular configuration with a Nilavilakku at the centre) and Parichamuttukali (an ancient martial dance form where Syrian Christian men with swords and shields follows the movements and steps of Kalaripayattu) still exist amongst the Saint Thomas Syrian Christian community.

Church architecture
The earliest documentary evidence is Tharisapally Copper Plate, which refers to the construction of the church of Tharisapally in Quilon between 823 and 849 AD. Antonio Gouvea, Portuguese envoy to Malabar, mentions in his 16th-century work Jornada that almost all the churches of Saint Thomas Christians followed the models of Hindu temples of that period, but were distinguished by the huge granite cross in the front yard of the church. Despite the external similarity with temples, the structuring of the interior space of the church always followed the East Syriac architectural theology. Thus the contemporary style is formed as an amalgamation of Indian architecture and Assyrian liturgical concepts. The church is arranged east-to-west, with the interior structured into three levels: the madbaha (sanctuary), the qestroma (choir) and the haykla (nave).

The madbaha, arranged in the topmost platform at the eastern side of the building, represents Heaven. The primary altar is attached to the eastern wall. To the north of the madbaha is the diaqonikon (sacristry); to the south is the baptistery.The madbaha is protected with rails and is veiled by a red curtain most of the time; this is opened during the Holy Qurbana (Eucharist). An oil lamp within the sanctuary is kept glowing at all times to represent the presence of God. The madbaha is connected to the qestroma and haykla by a low-walled path called the sqaqona. The qestroma contains seats for the choir and lower clergy. The haykla contains an elevated platform or bema, which includes an altar, two lecterns for reading, and chairs for higher clergy. Worshipers stand before the altar, with separate seating for men and women.

The main entrance is on the western side of the building; a vestibule, pillars, pilasters, and other architectural ornaments adorn the front end, and a flag mast stands in the front yard. One or two bells are installed in the back yard to signal the timing of ritual services, the death of a church member, or to inform the public of calamities.

The Persian Crosses
The East Syriac Churches of the St. Thomas Christians have accepted the Persian cross as their symbol. They call it the Nasrani Menorah or Mar Thoma Sleeva (St. Thomas' Cross). There are several interpretations for the St. Thomas Christian Symbol. The interpretation based on Christian Jewish tradition assumes that its design was based on Jewish menorah, an ancient symbol of the Hebrews, which consists of seven branched lamp stand (candelabra). The St. Thomas' Cross also appears on the official emblem of the Malankara Orthodox Syrian Church.

The interpretation based on local culture states that the Cross without the figure of Jesus and with flowery arms symbolising "joyfulness" points to the resurrection theology of St. Paul, the downward-facing bird (most likely a dove) on the top represents the role of the Holy Spirit in the resurrection of Jesus Christ. The Cross indicates Christ. The lotus symbolizing God the Father, who has begotten the Son. The three steps indicate Calvary and symbolise the Church, the channel of grace flowing from the Cross. The lotus may also symbolise the cultural association with Buddhism and the Cross over it shows that Christianity was established in the land of Buddha.

Today
Writing in 2010, Devika and Varghese noted that "[The St. Thomas Christians] are at present a substantial minority, a powerful presence in all fields of life in Kerala."

Socioeconomic status
Even though the Saint Thomas Christians had to compromise their social and religious privileges in the aftermath of Portuguese subjugation, they started reemerging as a powerful community from the 19th century onward. They played a pioneering role in many spheres such as banking, commerce, cash crops, print media, film industry etc. Around 2003, among Saint Thomas Christians, 17.4 percent of the adult population are self-employed–the highest rate statistically among all the communities in the state of Kerala. Saint Thomas Christians lead all others with respect to per capita ownership of land, with many of them owning large estates. With changing conditions, they have shifted from the agriculture of rice and coconut to plantation based agriculture and the trading of rubber, spices and cash crops. They also take a prominent role in the educational institutions of Kerala and throughout India. The educational accomplishments of the community have helped its members to attain a good proportion of the Central and State Government jobs. Kerala Government in the year 2024 happened to present the community wise account of the government employees in its Legislative Assembly. According to the data, out of the then total 5,45,423 government employees in the state, 73,713 are from forward Christian communities, ie., Saint Thomas Christians, which accounts for the 13.5 percent of the total government employees. With their level of education and limited employment opportunities within the state of Kerala, they became the community with the highest rate of migration. Their resultant foreign remittances have also helped the socioeconomic progress of the community. According to the Kerala Migration Survey (1998) by the Center for Developmental Studies, Kerala, Saint Thomas Christians top all other communities in Kerala with respect to the Socioeconomic Development Index which is based on parameters such as the possession of land, housing & consumer durables, education and employment status.

Demographics
The Saint Thomas Syrian Christians form 12.5 percent of the total population of Kerala and 70.73 percent of the Christians in the state. K. C. Zachariah notes that the 20th century was period of significant transition for the Saint Thomas Christians in terms of its demographic and socioeconomic status. Around 1900, the community was concentrated in a few areas, was geographically static and "... was characterised by very high death rate, very high birth rate, very early age at marriage, and 10 to 12 children per married woman". The population had increased eight-fold during the preceding century, from a base figure of about 100,000, and comprised nearly 50 per cent children. But, the population growth of Saint Thomas Christians came down drastically after the 1960s, with the lowest birth rate, highest age at marriage, highest family planning user rate, and lowest fertility rate compared to other communities in Kerala. The proportion of children has come down to less than 25 percent. The absolute and relative size of the community is in a diminishing trend and is approaching a zero population growth regime.

, in Kerala, more than 85 per cent of the Saint Thomas Christian population live in the seven southern districts of the state – Kollam, Pathanamthitta, Alappuzha, Kottayam, Idukki, Ernakulam and Trissur. They have also migrated to other cities in India like Ooty, Mangalore, Bangalore, Chennai, Pune, Delhi, Mumbai, Coimbatore, Hyderabad and Kolkata. Migration steeply increased in the post-independence period and major destinations were United States of America, Canada, Western Europe, Australia and the Middle East. According to a rough estimate, 20–25 percent of the Saint Thomas Christians live outside the state of Kerala.

Syrian Christian caste status
Despite the sectarian differences, Saint Thomas Syrian Christians share a common social status within the Caste system of Kerala and is considered as an Upper caste community.

In historic kingdoms of Kerala such as those of Cochin and Travancore, Saint Thomas Christians were granted caste privileges that put them on the same level as Upper caste Hindus. Anthropologist, L.K. Ananthakrishna Iyer recorded that they were given privileges in addition to those granted to groups such as Nairs, such as the right to have enclosures in front of their houses, which was otherwise only granted to the Brahmins, and were placed "almost on par with the Sovereigns". They followed the same rules of caste and pollution as did Hindus, and sometimes they were considered to be pollution neutralisers. Decree II of Action IX of the Synod of Diamper enforced by the Portuguese Inquisition in 1599 prohibited the practice of untouchability by the Saint Thomas Christians except in practical circumstances when required by law and when it was necessary to ensure social contact with the Varna Hindus.

They tend to be endogamous, and tend not to intermarry even with other Christian groupings. Internal division of Saint Thomas Christians into Northists and Southists and also into a number of sects based on the ecclesiastical orientation makes the pattern of segmentation an exceedingly complex. Forrester suggests that the Northist-Southist division forms two groups within the Saint Thomas Christian community which are closely analogous to sub-castes.

Christian conventions
The Maramon Convention is one of the largest annual Christian gatherings in Asia. It takes place in Maramon, near Kozhencherry, during February on the vast sand-bed of the Pamba River next to the Kozhencherry Bridge. The first convention was held in March 1895 for 10 days.

Another major convention in Kerala is the annual Central Travancore Convention held at Saint Stephen's Cathedral, Makamkunnu of the Malankara Orthodox Syrian Church. The first convention was held in 1915.

One of the biggest conventions of the Malankara Orthodox Syrian Church is the Kallooppara Orthodox Convention. It takes place on the Koithottu sand banks of the Manimala river with over 5,000 annual participants. This convention was started in 1943 lasting 8 days.

Ranni Orthodox Convention is an annual convention of the Malankara Orthodox Syrian Church. The convention is now held in Ranni town at Mar Gregorios Catholicate Centre and began in 1967.

Mallapally Orthodox Syrian Convention of the Malankara Orthodox Syrian Church is an annual convention in Mallapally, Pathanamthitta. The first convention took place in 1989 at Mallapally Valiyapally (St. John's Bethany Orthodox Valiyapally).

Trivandrum Orthodox Convention is an annual convention organized by Trivandrum Orthodox Diocese. The convention takes place at Holy Trinity Aramana, Ulloor and was started in 1988.
