A listmember from the Church of South India has reminded me of the Golden Jubilee of his Province, and supplied the following details.
The Church of South India is the first example in Church History of the union of episcopal and non-episcopal Churches. (A fundamental principle was the acceptance into a united ministry of all existing ordained ministers whether possessing episcopal orders or not. After a period of about 30 years it was intended that all ministers would be episcopally ordained.) It was inaugurated on 27th September 1947 in Madras, South India. The joining churches were: the Anglican Church, the Methodist Church, the South Indian United Church (itself a union of Presbyterian and Congregationalist Churches that happened in 1904) and later, the Basel Mission Churches.
The Mission of the Church is to share the love of Jesus Christ with the people of India through:
A) Proclamation of the Good News of Jesus
B) Responding to human need through institutions (schools, hostels for poor children, hospitals etc.) and through emergency relief work.
C) Striving to build a more just society through Community Development Projects, Skills Training Programmes for the marginalised and disadvantaged sections of the people.
D) Programmes to preserve the integrity of God's creation.

O God, who to an expectant and united Church didst grant at Pentecost the gift of the Holy Spirit, and hast wonderfully brought into one fold those who now worship thee here: Grant, we beseech thee, the help of the same Spirit in all our life and worship, that we may expect great things from thee, and attempt great things for thee, and being one in thee may show to the world that thou didst send Jesus Christ our Lord, to whom with thee and the Holy Spirit, be all honour and glory, world without end.
