The book is about the visit of St. Thomas to Kearalam in the first century CE. It discusses whether he was a Jew when he visited and what was his message. It gives a broad background of various aspects of religion as it existed in the first century in Palestine and Keralam. It also deals with the spread of the Roman empire and how it affected the beginning and development of Christianity as a distinct religion with its root is Judaism. There is also a brief account of the Gospel Of Thomas an apocryphal work which is supposed to have been penned by Thomas or someone who wrote it on Thomas' behalf. There are brief references to Hinduism, Buddhism, Jain religion etc and how they may have been the major religious streams in Keralam and how they could have been the first adherents to nascent Christianity. This is in contrast to the common belief that Thomas attracted mainly Brahmans. The book establishes that there were no Brahmans in Keralam in the first century CE and the belief came to Keralalm after the infusion of the Portuguese in Keralam and they had a vested interest in the Brahman conversions theory.Lastly the book deals with the present status of the community that became Christians in the first century. The book ends with a plea that the Thomas heritage needs to be preserved and respected.
