Christians in India are members of different church denominations though some are also non-denominational. The state of Kerala is home to the Saint Thomas Christian community, an ancient body of Christians who according to tradition trace their origins to the evangelistic activity of Thomas the Apostle in the 1st century. They are now divided into several different churches and traditions. There are East Syriac Rite denominations: the Syro-Malabar Catholic Church and the Chaldean Syrian Church. There are West Syriac Rite denominations: the Malankara Orthodox Syrian Church, the Jacobite Syrian Christian Church , the Mar Thoma Syrian Church, the Syro-Malankara Catholic Church, and the Malabar Independent Syrian Church. Saint Thomas Anglicans are members of the Church of South India (C.S.I.). Roman Rite Catholicism was introduced to India by the Portuguese, Italian Capuchins and Irish Jesuits from the 16th century onwards, under the influence of its allied empires, resulting in the establishment of communities such as the Bettiah Christians of Bihar. Many Christian schools, hospitals and primary care centres originated through the Roman Catholic missions brought by the trade of these countries.
