The Israeli consul, Pinchas E. Lapide, in his book, Three Popes and the Jews (New York: Hawthorn Books, Inc., 1967) critically examines Pope Pius XII. According to his research, the Catholic Church under Pius XII was instrumental in saving 860,000 Jews from Nazi death camps (p. 214). Could Pius have saved more lives by speaking out more forcefully? According to Lapide, the concentration camp prisoners did not want Pius to speak out openly (p. 247). As one jurist from the Nuremberg Trials said on WNBC in New York (Feb. 28, 1964), "Any words of Pius XII, directed against a madman like Hitler, would have brought on an even worse catastrophe... [and] accelerated the massacre of Jews and priests."
Yet Pius was not totally silent either. Lapide notes a book by the Jewish historian, Jenoe Levai, entitled, The Church Did Not Keep Silent (p. 256). He admits that everyone, including himself, could have done more. If we condemn Pius, then justice would demand condemning everyone else.
He concludes by quoting from the Talmud that "whosoever preserves one life, it is accounted to him by Scripture as if he had preserved a whole world." With this he claims that Pius XII deserves a memorial forest of 860,000 trees in the Judean hills
(pp. 268-9). It should be noted that six million Jews and three million Catholics were killed in the Holocaust.The recent slander against the Church and Pope Pius XII can be traced back to 1963 with Rolf Hochhuth's play, "The Deputy." In this play Hochhuth criticized Pius for being silent and portrayed his silence as cold indifference. Even though fiction, people took it as fact.http://users.binary.net/polycarp/piusxii.html
