One of my earliest teachers of Jesus' nonviolence was the great Mennonite theologian John Howard Yoder.
I remember discovering in the fall of 1982 his seminal work, The Politics of Jesus, and devouring it. There I found for the first time someone who integrated my passion for Gandhian nonviolence with my devotion and discipleship to Jesus. Yoder answered all my questions. He outlined a theological way to understand the Gospel that made sense.
