During the reign of the Mughal emperors in India, the Portuguese traders landed at Goa, Cochin and the Malabar coast, bringing in their religion Roman Catholicism and idol worship of Jesus, Mary and other saints and this paved the way for many Roman Catholic churches being built in the name of Christianity. (Roman Catholic religion is not Christian). Even Velankannai and Mylapore in the Coromandel coast were victims of these Portuguese traders. These were significantly different from the Christian churches – structurally and scripturally – that were originally built by the local Christians who had become believers from the time of St Thomas.

Portuguese and the French colonised India and spread their idol-worshipping Roman Catholic religion in their colonies. RCs are not Christians as they are wrongly understood by today's natives and the ruling class Brahmins.
