How did the life and intellectual development of Lesslie Newbigin shape his role as a significant twentieth-century theologian and church leader? Geoffrey Wainwright, a scholar with decades of personal and professional familiarity with Newbigin, utilizes archival research and personal correspondence to reconstruct the subject's theological evolution. The book argues that Newbigin's work represents a critical intersection of ecumenical movement, missionary practice, and post-colonial theological reflection. By examining Newbigin's writings and public ministry, Wainwright provides a comprehensive framework for understanding his enduring influence on global Christianity.

Scholars and theologians recognize this work as the definitive intellectual biography of Newbigin. Readers frequently note the academic density of the prose, which is well-suited for those familiar with twentieth-century ecumenical history.
