Agree. Pius XII could not do much in The Third Reich nor in German-occupied countries where RC priests were sent to Nazi concentration camps.
But, Independent State of Croatia was not occupied by Nazis, it was Nazi Ally. And there, out of 1700 RC priests, some 1400 participated in slaughter of innocents. The Personal envoy of Pius XII was there during the war and it is highly unlikely that Pius XII did not know what was going on there.
Rome was liberated June 5, 1944. Pius XII supported the Nazis even after demise of the Third Reich May 9, 1945. Ratlines were run from the Vatican, surrounded by Allied forces. Not exactly definition of "antagonistic empire".
Pius XII support to Nazis after The Third Reich fell is the issue we are dealing here with.
Monsignor Hugh O’Flaherty. Check out his story. This is the kind of action taken by just one Monsignor.
Pastor Gustaw Manitius.
There is a long long list of real leaders who stood behind their beliefs.
What surprises me regarding the rabid Catholic response to this is that they conveniently overlook the death of their fellow Catholics.
Our contention is not with our fellow Christians in the Catholic Church and their devotion to Christ but rather with the Papacy whose behavior regarding the protection of war criminals which was ant-Christian.
