The book scrupulously covers the concept of mission and ecumenism of the Christian Conference of Asia (CCA) from 1957 to 2007. CCA has been a vital instrument in bringing up the human communities in Asia, by strengthening ecumenical life at the local, national and regional levels thereby deciding the future of ecumenical life at the global level. The author strongly believes that the CCA could meet this agenda through its evolutionary understanding of mission.
