This contribution aims to demonstrate the analysis of structural violence carried out by theologian B. Häring over forty years ago and the solution he proposed to address resignation in the face of the inevitability of war and the justification of just and holy wars. His proposal is still highly relevant today, even though it was underestimated at the time. He advocated overcoming all vindictive justice by tracing the dynamics of non-violence in the light of the Gospel and the "new weapons of peace", referring to masters such as Gandhi and Martin Luther King and the healing virtue of non-violence.
