The 1,500-year-old legacy of Christianity in Tamil Nadu

Health · Published 19 October 2026 Swipe more like this →

In short: Christianity in Tamil Nadu is not a modern import but a faith with roots stretching back to the first century. From the ancient martyrdom of St. Thomas to the massive annual pilgrimages of the 'Lourdes of the East,' the region's spiritual landscape is a complex tapestry of colonial history and local devotion.

The presence of Christianity in Tamil Nadu is anchored in the tradition of St. Thomas, one of the twelve apostles of Jesus. He is believed to have arrived on the Malabar Coast around AD 52, preaching between 52 AD and 72 AD. Tradition holds that he was martyred on St. Thomas Mount in Chennai, where the Santhome Basilica now stands. One of the oldest churches in the world, St. Mary's Orthodox Church in Thiruvithamcode, was reportedly built by him in 63 AD. The faith expanded significantly during the colonial era through the efforts of Portuguese, Dutch, British, and Italian missionaries. In the 16th century, St. Francis Xavier conducted extensive missionary work in the coastal areas, notably in Kottar. His efforts led to the establishment of St.

Francis Xavier's Cathedral in 1600, which was built on land granted by a local king in recognition of Xavier's role in averting an invasion. By the 18th century, European missionaries like William Tobias Ringeltaube further propagated the faith, establishing the first Protestant church in Mylaudy in 1806. Today, Christians make up approximately 6% of Tamil Nadu's population, with a high concentration in the southern districts of Kanyakumari, Thoothukudi, and Tirunelveli. The religious landscape is diverse, featuring the Latin Church, the Church of South India (CSI), Pentecostals, and the Salvation Army. The latter, which began in 1892 following a vision by Major Deva Sundaram, now operates over 1,000 churches and provides extensive medical and social services across the state.

The region also hosts some of India's most significant pilgrimage sites. The Basilica of Our Lady of Good Health in Velankanni, known as the 'Lourdes of the East,' draws nearly 5 million pilgrims annually to a shrine founded on 16th-century miracles. Similarly, the Santhome Basilica in Chennai, rebuilt by the British in 1893, remains a vital national shrine and pilgrimage center for the global Christian community.
