Already in 1939 the MCCS decided to start mission work among Turkish peoples and Muslims in India and the following year the first missionaries arrived in Mumbai.
On October 19, 1963, 22 delegates from the three congregations in Pune, Mumbai and Sholapur, among them 6 missionaries, assembled and founded the Hindustani Covenant Church (HCC).
Social work has comprised humanitarian aid in case of catastrophic events like floodings and earth quakes, community development, health care and education.
The Church runs three High schools, in Gulbarga, Nannaj and Sholapur and one Junior College of Science in Solapur.
Besides, CSS offers courses leading to certain professions in order to help people to find a sustainable livelihood.
