The Church of South India (Abbreviation: CSI) is a union of many Protestant denominations spread throughout South India. It is the largest Protestant Church in India and second largest Christian church after the Catholic Church in India . It is one of the four United Churches in the Anglican Communion.
The inspiration for this Union was born out of ecumenism inspired by the self-pronouncing words of Jesus Christ as found in Gospel of John, 21
That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
That they all may be one is also the motto of the Church of South India .
Discussions about the merging of South India's Protestant denominations began at a 1919 conference at Tranquebar (today known as Tharangambadi), and by the independence of India in 1947, the union was achieved and the CSI officially established .
The School for Small Farmers is a specific agency catering to the needs of the farming communities in their Dalit and Adivasi congregations .
In Indian mythology, the lotus flower is the seat of the Creator. It is also known variably as those that are born in mud and the flower of the sun. These symbolisms are adopted to interpret the position of God, and the nature and role of the people in the CSI
The petals of the lotus and the cross are knitted together with the symbol of the fiery-tongues of the Holy Spirit as referenced in the book of the Acts of the Apostles. It is an expression of the people's communion with God. The original colors, red (for life) and purple (for piety and ecclesiastical) on a white backdrop communicate the nature of the mystical union where an inseparable companionship is established between God and humanity.
The motto and the name of the CSI is placed in a circle around the lotus and the cross. The words are taken from the prayer of Jesus Christ who prayed not only for the church but also for the whole world. This universality is portrayed by placing the words in a form of circle, a symbol which also represents the universe. It calls for the unity of both the church and all peoples of India.
The central position of the cross in the logo conveys the idea that it was the sacrifice that was made by Jesus on the cross that is the foundation of the Church. The four ends of the cross painted in deep color indicates that it is the cross that guides all Chrsitians to join in one stream to pray and labor united for a peaceful coexistence and communal harmony.
The CSI, CNI, and Mar Thoma Church jointly formed the Communion of Churches in India (CCI) in 1978 for mutual recognition of the ministry and leaders, intercommunal relationship, and to explore possibilities of working together especially in the field of evangelization in India and other areas of cooperation in the fulfillment of the mission of the Church.
