"The election of Cardinal Pacelli is not accepted with favor in Germany because he was always opposed to Nazism." The day after Pius XII's election (March 3, 1939) in the Nazi newspaper, Berliner Morganpost

"Above all, we acknowledge the Supreme Pontiff and the religious men and women who, executing the directives of the Holy Father, recognized the persecuted as their brothers and, with great abnegation, hastened to help them, disregarding the terrible dangers to which they were exposed." September 1945, Dr. Joseph Nathan, representing the Italian Hebrew Commission.
"We share in the grief of humanity. …When fearful martyrdom came to our people, the voice of the Pope was raised for its victims.

Golda Meir, in 1958, at the death of Pope Pius XII

"Only the Church stood squarely across the path of Hitler’s campaign for suppressing truth. …The Church alone has had the courage and persistence to stand for intellectual truth and moral freedom." Albert Einstein, in Time magazine (December 23, 1940)
