Christianity in Kerala
Christianity is the third-most practiced religion in Kerala with 19% of the population according to the Indian census. Although a minority, Christians represent a much larger percentage of the population of Kerala than of India considered as a whole. It's a significant minority within Christianity in India, but has contributed a lot towards the progress and development of the nation in the fields of education, healthcare, social uplift etc. Christianity is believed to have reached the shores of Kerala in 52 CE with the arrival of St Thomas, one of the Twelve Apostles of Jesus Christ. Saint Thomas Christians (also known as Syrian Christians or Nasrani) include Syro-Malabar Catholic, Malankara Orthodox, Jacobite, Marthoma, Syro-Malankara Catholic and a few members of the Church of South India. Latin Rite Christians were converted by the Portuguese in the 16th and 19th centuries mainly along the coastal areas of Kerala.
The origins of Christianity in Kerala go back to the earliest period of the Church itself. In fact, there is a tradition among the Christian people of Kerala that St. Thomas the Apostle, one of the twelve disciples of Jesus, landed on the Kerala coast in 52 A.D. and preached the Gospel. He is said to have first converted about a dozen Brahmin families to Christianity. He organized Christian communities, in several places and established seven churches in Kerala and then at last got martyrdom in Mylapore, Chennai, in 72 A.D. However the exact year of his arrival here is disputed due to lack of credible historical evidence, despite the fact that the fruits of his hard labour being visible everywhere. His tomb is venerated by people of all religions even today. In 345 A.D., a Palestinian business man, Thomas Cana, along with 72 families came and settled in Kerala, thereby augmenting the Christian community. A second period of intense Latin Christian missionary activity began with the arrival of European missionaries since the discovery of sea route to India by Vasco da Gama in 1498.
