The Church of South India is an ecumenical body of several denominations in the four southern most states of mainland India and also the Jaffna Diocese of Sri Lanka.
The Church of South India serves and unites churches in Southern India. The Church has a variety of programs supporting education, development, medical care and empowerment of the people of Southern India. Most of the Christians in India are among the poorest segments of society. Ministries to these communities are aimed at lifting them permanently out of the historically, caste-defined, poverty and discrimination which has kept them poor.
