What is this world war, with all its attendant circumstances, whether they be remote or proximate causes, its progress and material, legal and moral effects? What is it but the crumbling process, not expected, perhaps, by the thoughtless but seen and depreciated by those whose gaze penetrated into the realities of a social order which hid its mortal weakness and its unbridled lust for gain and power? That which in peace-time lay coiled up, broke loose at the outbreak of war in a sad succession of acts at variance with the human and Christian sense. International agreements to make war less inhuman by confining it to the combatants to regulate the procedure of occupation and imprisonment of the conquered remained in various places a dead letter. And who can see the end of this progressive demoralization of the people, who can wish to watch helplessly this disastrous progress? Should they not rather, over the ruins of a social order which has given such tragic proof of its ineptitude as a factor for the good of the people, gather together the hearts of all those who are magnanimous and upright, in the solemn vow not to rest until in all peoples and all nations of the earth a vast legion shall be formed of those handfuls of men who, bent on bringing back society to its center of gravity, which is the law of God, aspire to the service of the human person and of his common life ennobled in God.

Mankind owes that vow to the countless dead who lie buried on the field of battle: The sacrifice of their lives in the fulfillment of their duty is a holocaust offered for a new and better social order. Mankind owes that vow to the innumerable sorrowing host of mothers, widows and orphans who have seen the light, the solace and the support of their lives wrenched from them. Mankind owes that vow to those numberless exiles whom the hurricane of war has torn from their native land and scattered in the land of the stranger; who can make their own the lament of the Prophet: “Our inheritance is turned to aliens; our house to strangers.” Mankind owes that vow to the hundreds of thousands of persons who, without any fault on their part, sometimes only because of their nationality or race, have been consigned to death or to a slow decline. Mankind owes that vow to the many thousands of non-combatants, women, children, sick and aged, from whom aerial war-fare—whose horrors we have from the beginning frequently denounced—has without discrimination or through inadequate precautions, taken life, goods, health, home, charitable refuge, or house of prayer. Mankind owes that vow to the flood of tears and bitterness, to the accumulation of sorrow and suffering, emanating from the murderous ruin of the dreadful conflict and crying to Heaven to send down the Holy Spirit to liberate the world from the inundation of violence and terror. — from the Christmas radio address of 1942
