The following is an analytical review on Lesslie Newbigin’s The Open Secret: An Introduction to the Theology of Mission Revised Edition.
Leslie Newbigin (1909-1998) was a theological missiologist/missionary and a missiological theologian. There are over six decades worth of his writings on mission theology and practice. Thus, he is considered to have had one of the greatest influences on the theology of mission in the twentieth century. Furthermore, Newbigin was a scholar practitioner since his works were always rooted in his living relationship with Jesus Christ; after all, he modeled what he wrote. He was also a Western missionary to India from 1936-1974, and upon returning to Great Britain, his missionary focus turned to the West (Shenk 1998).
The thesis of this book is that Christian mission is an open secret. It is open in the sense that the gospel is proclaimed to all without any boundaries, but it is a secret in that “it is manifest only to the eyes of faith” (Location 2556). As a result, mission cannot be relegated as a side task of the church, but it is the central calling and purpose of the church, yet the church does not own the mission, the mission is God’s (Location 256). Newbigin’s prophetic call to the church is for it to reemphasize its missionary character “to bring all things to their true end in the glory of the triune God” (Location 2556).
