Ecumenism

    The CSI is a member of the Anglican Communion. It is also a member in the World Council of Churches, World Alliance of Reformed Churches, and the National Council of Churches in India. The CSI is in full communion with the Malankara Mar Thoma Syrian Church of Kerala and Church of North India (CNI).
    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.
