Just War as a Theory, Just Peace as a Virtue

Abstract

Pope Francis both grants the right to use armed force in self-defense and regards all war as ‘a defeat for humanity’. This seeming paradox can be explained by the fact that what is a theoretically just use of force (according to the criteria of just war theory) inevitably results in unjust violence when carried out in practice. The undertaking, processes and practices of war are highly susceptible to what Augustine called the libido dominandi. The theory of just war is carried forward in institutions of actual war-making that foster escalation, discourage restraint, and adapt the theory itself to accommodate increasing violence. ‘Just war’ fails to embody the social and institutional virtue of justice. Thus, as Pope Francis exhorts, the Christian ethics of war and peace should prioritize the theory of just peace and the cultivation of peacebuilding dispositions, practices, and institutions. These strategies favor justice, but success is not guaranteed.
