One way to define violence is to see it as the act of forgetting or ignoring who we are — brothers and sisters of one another, each one of us a child of God. Violence occurs in those moments when we forget and deny our basic identity as God's children, when we treat each other as if we were worthless instead of priceless, when we cling to our own selfish desires, possessions, and security.
From a review of John's book, by Frederic and Mary Ann Brussat:
With great clarity and insight Dear lays out six points that comprise the spirit of nonviolence: (1) It means remembering we are all God's children; (2) it flows from unconditional, active love; (3) It invites solidarity with the poor and the oppressed; (4) it involves resistance and truth; (5) It is rooted in prayer; and (6) it is a way of transformation. The author challenges us to make a vow of nonviolence as a way of witnessing to others that God has disarmed us and wants to disarm us all.
