World War II During World War II Pius saw his primary obligation as being to ensure the continuation of the "Church visible" and its divine mission. Pius XII lobbied world leaders to prevent the outbreak of World War II and then expressed his dismay that war had come in his October 1939 Summi Pontificatus encyclical. He followed a strict public policy of Vatican neutrality for the duration of the conflict mirroring that of Pope Benedict XV. In 1939, Pius XII turned the Vatican into a centre of aid which he organized from various parts of the world. At the request of the Pope, an information office for prisoners of war and refugees operated in the Vatican under Giovanni Battista Montini, which in the years of its existence from 1939 until 1947 received almost 10 million (9,891,497) information requests and produced over 11 million (11,293,511) answers about missing persons. McGoldrick (2012) concludes that during the war: Pius XII had genuine affection for Germany, though not the criminal element into whose hands it had fallen; he feared Bolshevism, an ideology dedicated to the annihilation of the church of which he was head, but his sympathies lay with the Allies and the democracies, especially the United States, into whose war economy he had transferred and invested the Vatican's considerable assets. Outbreak of war Summi Pontificatus Summi Pontificatus was the first papal encyclical issued by Pope Pius XII, in October 1939 and established some of the themes of his pontificate. During the drafting of the letter, the Second World War commenced with the German/Soviet invasion of Catholic Poland—the "dread tempest of war is already raging despite all Our efforts to avert it". The papal letter denounced antisemitism, war, totalitarianism, the attack on Poland and the Nazi persecution of the church. Pius XII reiterated church teaching on the "principle of equality"—with specific reference to Jews: "there is neither Gentile nor Jew, circumcision nor uncircumcision". The forgetting of solidarity "imposed by our common origin and by the equality of rational nature in all men" was called "pernicious error". Catholics everywhere were called upon to offer "compassion and help" to the victims of the war. The Pope declared determination to work to hasten the return of peace and trust in prayers for justice, love and mercy, to prevail against the scourge of war. The letter also decried the deaths of noncombatants. Following themes addressed in Non abbiamo
