The Church of South India celebrates 70 years as a model for inter-church relationships. From the grassroots, it joins together many local denominations and congregations. At the global level, it participates in multiple international religious bodies:
“The Diocese of Madras laid on a fellowship lunch for several thousand people last month as the Church of South India (CSI) celebrated the 70th anniversary of its formation. The Church of South India was formed on 27 September 1947 when the Church of England in southern India and the Methodist Church in South India joined the Congregational, Presbyterian and Reformed churches in the already-united South India United Church. As a united church, in addition to being a full member of the Anglican Communion, the Church of South India is also a member of other global Christian communions, including the World Methodist Council and the World Communion of Reformed Churches.”
