No, religion allowed Hitler to start world war 2.
Jews have always been Europe's scapegoats, and it is not unexpected that it would be used by the Nazi power brokers.
Though a handful of priests and nuns protested Hitler’s atrocities—and suffered for it—the Vatican as well as the Catholic Church and its army of clergy gave either active or tacit support to the Nazi tyranny, which they regarded as a bulwark against the advance of world Communism.
Sitting pretty in the Vatican, Pope Pius XII let the Holocaust on the Jews and the cruel persecutions of Jehovah’s Witnesses and others proceed uncriticized. It is ironical that Pope John Paul II, on visiting Germany in May 1987, should glorify the anti-Nazi stand of one sincere priest. What were the other thousands of the German clergy doing during Hitler’s reign of terror?
A pastoral letter issued by the German Catholic bishops in September 1939 at the outbreak of World War II provides enlightenment on this point. It reads in part: “In this decisive hour we admonish our Catholic soldiers to do their duty in obedience to the Fuehrer and to be ready to sacrifice their whole individuality. We appeal to the Faithful to join in ardent prayers that Divine Providence may lead this war to blessed success.”
Such Catholic diplomacy illustrates the kind of harlotry that religion has engaged in over the past 4,000 years in wooing the political State in order to gain power and advantage. Such religio-political relationships have fostered warfare, persecutions, and human misery on a vast scale. How happy mankind can be that Jehovah’s judgment upon the great harlot is at hand. May it soon be executed!
