Radio Moscow’s insinuation that Pius XII was “Hitler’s Pope” attracted no attention whatsoever in the West, because the pope’s heroic support of the Allies and generous aid to the Jews during World War II was still fresh in people’s minds. They knew this man too well, based on the word of the highest Western authorities, for the insinuation to take hold.
On August 3, 1944, President Franklin D. Roosevelt wrote to the pontiff:
I should like to…take this occasion to express to His Holiness my deeply-felt appreciation of the frequent actions which the Holy See has taken…to render assistance to the victims of racial and religious persecutions.
On September 6, 1944, Winston Churchill announced: “I have spoken today to the greatest man of our time.” Churchill admired Pius XII’s “simplicity, sincerity and power.” Albert Einstein wrote: “Only the Church protested against the Hitlerian onslaught on liberty. Up till then I had not been interested in the Church, but today I felt a great admiration for the Church, which alone has had the courage to struggle for spiritual truth and moral liberty.” The secular magazine Wisdom editorialized: “Of all the great figures of our time, none is more universally respected by men of all faiths than Pope Pius XII.”
