St. Thomas, one of the twelve apostles of Jesus Christ, is the founder of the church in India. Christian writers and historians from the 4th century refer to the evangelistic work of Apostle Thomas in India, and the Indian Christians ascribe the origin of their church to the labors of the apostle in the 1st century.

"Insistent tradition ascribes the introduction of Christianity to India to the Apostle Thomas, one of the original Twelve."

It is reasonable to believe that the St. Thomas came to India, preached the gospel, established the church and died there as a martyr. It is believed that St.Thomas arrived in Cranganore, Kerala, India, in 52 AD He preached the gospel and founded churches at seven places; Cranganore, Palur, Paraur, Gokkamangalam, Niranam, Chayal and Quilon, and appointed prelates and priests. He was martyred on St. Thomas Mount near Mylapore, in 72. A.D., and his remains were buried at Mylapore Madras, India.
