Apostolic Origins: The St. Thomas Christians
The Syro-Malabar Catholic Church is an Eastern Catholic Church that traces its origins to St. Thomas the Apostle. According to tradition, he arrived at the ancient port of Muziris (Cranganore/Kodungallur) in Kerala in 52 AD, preached the Gospel, and established seven initial Christian communities—at Cranganore, Palayur, Kottakavu, Kokkamangalam, Quilon, Niranam, and Chayal—before his martyrdom at Mylapore in 72 AD.
Known historically as St. Thomas Christians or Nazranis (“followers of Jesus of Nazareth”), this community developed a Christian life deeply rooted in Indian culture.
Liturgical Heritage and the East Syrian Connection
From the early centuries until the late 16th century, the St. Thomas Christians maintained close fraternal communion with the East Syrian Church. Bishops sent from Mesopotamia and Persia oversaw spiritual and liturgical matters, while community administration was led by a local priest known as the Archdeacon of All India, in consultation with the Palliyogam, the local council or assembly.
Through this connection, the Church preserved the East Syriac liturgical tradition using Syriac, a form of Aramaic closely related to the language spoken by Christ, while remaining distinctively Indian in custom and society.
Colonial Encounters and the Struggle for Autonomy
The arrival of Portuguese explorers in the 16th century initiated a complex era marked by European oversight and the gradual Latinization of Indian liturgy and governance. After the Synod of Diamper (1599) and the suppression of the Archdeacon’s authority, tensions culminated in the Coonan Cross Oath of 1653 at Mattancherry, where the community stood together to reclaim its autonomy.
This period led to lasting jurisdictional divisions among the Nazranis. The branch that maintained communion with the Bishop of Rome became formally recognized in the 19th century as the Syro-Malabar Church—meaning the Syrian Christians of the Malabar Coast.
Restoration of Hierarchy and Autonomous Status
The late 19th and 20th centuries marked the revival of the Church’s indigenous identity. In 1896, Pope Leo XIII granted native Syrian bishops to lead the vicariates of Kerala. On December 21, 1923, Pope Pius XI officially established the Syro-Malabar Hierarchy.
On December 16, 1992, Pope John Paul II elevated the Syro-Malabar Church to a Major Archiepiscopal sui iuris (autonomous) Church, establishing the Major Archeparchy of Ernakulam-Angamaly as its see, under the leadership of its Major Archbishop and the Synod of Bishops.
A Global Community
Migration across India and to North America brought the faithful together in dedicated communities wherever they settled. In the United States, the St. Thomas Catholic Eparchy of Chicago serves this growing diaspora.
Our local mission continues this apostolic heritage by nurturing faith, preserving our ancient Syriac liturgy, and passing our spiritual legacy to the next generation.
