“Violence as a way of achieving racial justice is both impractical and immoral. I am not unmindful of the fact that violence often brings about momentary results. Nations have frequently won their independence in battle. But in spite of temporary victories, violence never brings permanent peace. It solves no social problem: it merely creates new and more complicated ones. Violence is impractical because it is a descending spiral ending in destruction for all. It is immoral because it seeks to humiliate the opponent rather than win his understanding: it seeks to annihilate rather than convert. Violence is immoral because it thrives on hatred rather than love. It destroys community and makes brotherhood impossible. It leaves society in monologue rather than dialogue. Violence ends up defeating itself. It creates bitterness in the survivors and brutality in the destroyers.”

Context: Violence as a way of achieving racial justice is both impractical and immoral. It is impractical because it is a descending spiral ending in destruction for all. The old law of an eye for an eye leaves everybody blind. It is immoral because it seeks to humiliate the opponent rather than win his understanding; it seeks to annihilate rather than to convert. Violence is immoral because it thrives on hatred rather than love. It destroys community and makes brotherhood impossible. It leaves society in monologue rather than dialogue. Violence ends by defeating itself. It creates bitterness in the survivors and brutality in the destroyers.

Context: A second way that oppressed people sometimes deal with oppression is to resort to physical violence and corroding hatred. Violence often brings about momentary results. Nations have frequently won their independence in battle. But in spite of temporary victories, violence never brings permanent peace. It solves no social problem; it merely creates new and more complicated ones.

Context: I met Malcolm X once in Washington, but circumstances didn't enable me to talk with him for more than a minute. He is very articulate … but I totally disagree with many of his political and philosophical views — at least insofar as I understand where he now stands. I don't want to seem to sound self-righteous, or absolutist, or that I think I have the only truth, the only way. Maybe he does have some of the answer. I don't know how he feels now, but I know that I have often wished that he would talk less of violence, because violence is not going to solve our problem. And in his litany of articulating the despair of the Negro without offering any positive, creative alternative, I feel that Malcolm has done himself and our people a great disservice. Fiery, demagogic oratory in the black ghettos, urging Negroes to arm themselves and prepare to engage in violence, as he has done, can reap nothing but grief.

Context: The Biblical view of the law, the courts, and the state is profoundly radical. The Bible looks upon the state as a kind of rebellious artifice; it is spurious, a human creation in rebellion against God.
In the Old Testament, when the first state is proposed in the person of Saul, the first King of Israel, God tells the prophet Samuel that this project spells rejection of God. The state and its legislature are in rebellion against, or rejection of, God. Its courts are a human fabrication, cannot promote justice and peace; they are founded in violence, and legalize violence.
The state holds together through police power, against the citizenry.
The state, conceived in violence, and backed by violence, will never achieve true peace.
