Since you brought up Edith Stein in this context, you should know that she wrote a letter in early 1933, shortly after Hitler’s election, to Pope Pius XI begging him to condemn Hitler and Naziism. Not only was the letter ignored, but shortly thereafter the Vatican, through the future Pius XII, executed its infamous Concordat with the Third Reich.
The letter can be read at:

You just don’t get it do you? If the Pope did what Edith Stein said, there would have been more more carnage. Why can’t you believe that? If you can’t believe that, believe this from Jewish people at the time:
How Pius XII Protected Jews
By Jimmy Akin
On April 28, 1935, four years before the War even started, Pacelli gave a speech that aroused the attention of the world press. Speaking to an audience of 250,000 pilgrims in Lourdes, France, the future Pius XII stated that the Nazis "are in reality only miserable plagiarists who dress up old errors with new tinsel. It does not make any difference whether they flock to the banners of social revolution, whether they are guided by a false concept of the world and of life, or whether they are possessed by the superstition of a race and blood cult."
3] It was talks like this, in addition to private remarks and numerous notes of protest that Pacelli sent to Berlin in his capacity as Vatican Secretary of State, that earned him a reputation as an enemy of the Nazi party.
The Pope’s efforts did not go unrecognized by Jewish authorities, even during the War. The Chief Rabbi of Jerusalem, Isaac Herzog, sent the Pope a personal message of thanks on February 28, 1944, in which he said: "The people of Israel will never forget what His Holiness and his illustrious delegates, inspired by the eternal principles of religion which form the very foundations of true civilization, are doing for us unfortunate brothers and sisters in the most tragic hour of our history, which is living proof of divine Providence in this world."

The Chief Rabbi of Rome, Israel Zolli, also made a statement of thanks: "What the Vatican did will be indelibly and eternally engraved in our hearts. . . . Priests and even high prelates did things that will forever be an honor to Catholicism."

After the war, Zolli became a Catholic and, to honor the Pope for what he had done for the Jews and the role he had played in Zolli’s conversion, took the name “Eugenio”—the Pope’s given name—as his own baptismal name. Zolli stressed that his conversion was for theological reasons, which was certainly true, but the fact that the Pope had worked so hard on behalf of the Jews no doubt played a role in inspiring him to look at the truths of Christianity.
