Was Christianity in India Older Than the Vatican? | The Apostolic Origins of the Indian Church Before the Synod of Diamper

Did Christianity come to India only after the arrival of the Portuguese, or did it have apostolic roots stretching back to the first century?

In this documentary-style presentation, we examine one of the most important questions in Christian history through the lens of historical documents, archaeological discoveries, ancient Syriac literature, and the testimony of the early Church Fathers.

This video explores the origins and development of Christianity in India before the Synod of Diamper (1599) and examines the evidence surrounding the ancient St. Thomas Christian (Nasrani) tradition.

In this video, we examine:

✝️ The ancient tradition of St. Thomas the Apostle's arrival in India (A.D. 52)

📖 The historical significance of the Acts of Thomas

👑 The archaeological confirmation of King Gondophares

🦴 The translation of St. Thomas's relics to Edessa (A.D. 232)

📜 Pantaenus' mission to "India" and the testimony of Eusebius of Caesarea

⛪ The witness of the early Church Fathers, including Gregory of Nazianzus, Jerome, Ambrose of Milan, Didymus the Blind, and Ephrem the Syrian

✝️ The Persian connection, Syriac liturgy, Persian Crosses, and the Tharisapalli Copper Plates

🚢 The arrival of the Portuguese and the events leading to the Synod of Diamper (1599)

This presentation distinguishes carefully between apostolic tradition, historical documentation, and archaeological evidence. Rather than relying on legend alone, it examines how multiple independent sources converge to demonstrate the antiquity of Christianity in India.

Whether you are a student of Church history, a theologian, or simply interested in the origins of the Indian Church, this presentation offers a comprehensive and historically grounded study of one of Christianity's oldest apostolic communities.

"Stand firm and hold fast to the traditions which you were taught, whether by word or by our epistle."

— 2 Thessalonians 2:15
