Incorrect. A violent attack on a priest or religious (other than in self-defense) resulted in immediate latae sententiae excommunication, according to canon law in force at the time. On that ground alone, Hitler (assuming he was actually a Catholic, subject to church discipline, in the first place) excommunicated himself hundreds of times over, by his murders of Catholic priests in Poland and elsewhere.
The issue with Goebbels' wife was not that she was a Lutheran, but that she was divorced. There was no church annulment. The marriage took place in a Lutheran ceremony, which made it invalid twice over according to the Catholic church (again, assuming that Goebbels was a Catholic at all and had not defected from the faith).
One of the most unforgiveable things the Church did was to allow the National Socialists access to their birth and baptismal records, which they used to identify Jews.
I wasn't aware that Jews kept baptismal records at all, much less that they kept them in Catholic churches. :-0
You are no doubt familiar with the immense numbers of Jews who were granted (spurious) baptismal records by the Catholic Church, to help them evade the Nazis*? Cardinal Roncalli (later Pope John XXIII) spent the war as Papal nuncio in Istanbul, where he issued phony baptismal papers for thousands of Jews. When thanked for his actions later, he said, in effect, "Thank Pius XII -- I did everything I did on his orders."
*Of course, this was only effective insofar as it convinced the Nazis that the bearer was not Jewish at all. The Nazis in general were perfectly willing to persecute or kill a Jew who converted to Christianity.
Suggesting that German Catholics and the Catholic church resisted Hitler and the Nazis is pure nonsense.
Suggesting that some German Catholics resisted Hitler is simply reciting a historical fact. Ever heard of Franz Jägerstatter? Bishop August Clemens von Galen?
And of course the man who tried to blow Hitler up. Did in fact, but did not kill him, because the Devil needed Hitler alive to ruin Germany.
