"Jesus has always been too much for us." - Richard Rohr
If Jesus never talked about it once, the churches will tend to be preoccupied with it (abortion, birth control, and homosexuality). And if Jesus made an unequivocal statement about it (Love one another as I have taught you), we tend to quietly shelve it and forget it.
At least one reason for our failure to understand Jesus’ clear teaching on nonviolence lies in the fact that the Gospel has primarily been expounded by a small elite group of educated European and North American men. The bias of white male theologians is typically power and control. From this perspective nonviolence and love of enemies makes no sense.
Because most of the church has refused to take Jesus’ teaching and example seriously, now much of the world refuses to take Christians seriously. “Your Christianity is all in the head,” they say. “You Christians love to talk of a new life, but the record shows that you are afraid to live in a new way—a way that is responsible, caring, and nonviolent. Even your ‘pro-life movement’ is much more pro-birth than pro-life.”
Like it or not, the church is finally becoming much more universal in its teaching. Marginalized and oppressed groups have a wealth of insights to offer us in reading the Gospel. The New Testament is being rediscovered by altogether different sets of eyes, raising very different questions and perspectives that we just never thought about before. We are just beginning to honor the voices of women, minorities, and many groups that have not had access to the power, privilege, and comforts of past theologians. Frankly, they represent the peoples who first heard the Gospel and allowed it to radically change their lives.
The big questions are more and more being answered at a peaceful and dialogical level, with no need to directly oppose, punish, or reject other people or religions. I sense the urgency of the Holy Spirit, with 7.5 billion humans now on the planet at the same time. Our future is either nonviolent or there is no future at all.
Ken Butigan writes in the foreword to John Dear’s book, The Nonviolent Life:
[This is] the urgency of the great choice we face as a species: will we choose to continue to affirm a culture of systemic violence—or will we build a culture of active, creative, and liberating nonviolence so that we can not only survive but thrive?
