He observed that violence builds up at three levels in a society. Primary violence is the everyday effect of structurally ingrained social injustice. This generates secondary violence - the revolt of the oppressed. And that in turn provokes tertiary violence - repression by the powerful to secure their privileged position. And so the spiral of violence tightens.
Camara was a true saint (in spite of the HRCC's efforts to quash liberation theology.) And a personal inspiration. He is one of the reasons I am unalterably opposed to violence in resistance.
