In a century marked by two devastating world wars, the fractious fundamentalist-modernist debate, and growing diversity in the church, Orie O. Miller helped to lead Mennonites from rural isolation to global engagement. In this engaging narrative, My Calling to Fulfill describes how Miller led Mennonite work in education, missions, peacemaking, postwar reconstruction, and mental health, and how he helped to mold every major Mennonite agency from Mennonite Central Committee to Mennonite Economic Development Agency. Filled with previously untold stories of Miller's personal life-his childhood, college years, marriage, and internal conflict between his commitment to his family and commitment to his beloved church-this inspiring and comprehensive biography traces the contours of twentieth-century Anabaptism through the theology and vocation of one of its most influential leaders. 444 Pages.
