It's less black and white than either of you guys are implying. You're taking about Pope Pius XII, who was Pope from 1939 to 1958. He's credited with saving hundreds of thousands of Jews through various means, including support to the resistance, but also by showing some had been converted/baptized, which in itself was controversial. But he also feared the Nazis were going to win the war and that the church would have to exist in a Nazi world. He never clearly spoke out against the holocaust, and though a lot of the things he said, including his sermons, can be taken as condemnation of Jewish persecution, the language was pretty subtle. Also, Hitler had an envoy secretly meeting with Pius from pretty early on, which many say was bad in itself. Still, he also helped the allies with intelligence, to the point where Hitler accused him of espionage and had plans to kidnap him.
