John XXIII on International Relations
April 11, 1963
The same law of nature that governs the life and conduct of individuals must also regulate the relations of political communities with one another. Some nations may have attained to a superior degree of scientific, cultural and economic development. But that does not entitle them to exert unjust political domination over other nations. It means that they have to make a greater contribution to the common cause of social progress. And just as individual men may not pursue their own private interests in a way that is unfair and detrimental to others, so too it would be criminal in a State to aim at improving itself by the use of methods which involve other nations in injury and unjust oppression. There is a saying of St. Augustine which has particular relevance in this context: "Take away justice, and what are kingdoms but mighty bands of robbers."
