Rethinking Ecclesia publication is a result of well thought and planned series of 8 consultations in the year 2018. These consultations are indeed a historical moment in the history of CSI as she commemorated 70 years of faithful journey and Reformation 500. All the papers presented and the meaningful conversations helped the Church of South India to engage more vigorously in the process of searching new theological directions and visions as CSI steps into a new decade. The theme "Being and becoming Christ communities - towards a borderless Church" were discussed from a) Biblical perspective, b) theological and ethical perspective, c) liturgical and missiological perspective, d) prophetic and diaconal perspective, e) empowerment and educational perspective, f) Health Healing and Harmony perspective, g)National and global ecumenical perspective.
