Hitler was not a Catholic, nor were those SS men.
You also apparently know nothing of latae sententiae excommunication.
Hitler was born and raised in a catholic family , he was an altar boy , Jesuit educated .
Most of the SS had the same history.
Mein Kampf.- "Therefore, I am convinced that I am acting as the agent of our Creator. By fighting off the Jews, I am doing the Lord's work."
Hitler said it again at a Nazi Christmas celebration in 1926: "Christ was the greatest early fighter in the battle against the world enemy, the Jews . . . The work that Christ started but could not finish, I--Adolf Hitler--will conclude."
John Toland wrote of Hitler's religion: "Still a member in good standing of the Church of Rome despite detestation of its hierarchy, he carried within him its teaching that the Jew was the killer of god. The extermination, therefore, could be done without a twinge of conscience since he was merely acting as the avenging hand of god - so long as it was done impersonally, without cruelty. "
Former Jesuit theologian Peter de Rosa describes the groundwork Catholic theology laid for Hitler and the Nazis: "[Catholicism’s] disastrous theology had prepared the way for Hitler and his ‘final solution.’ [The Church published] over a hundred anti-Semitic documents. Not one conciliar decree, not one papal encyclical, bull, or pastoral directive suggest that Jesus’ command, ‘love your neighbor as yourself,' applied to Jews."
I do know about that church practice, however a public rebuke and excommunication might have saved a few Jewish lives. They did not hesitate with Luther did that ?
The difference? Luther threatened THEM and THEIR power. Hitler only threatened the Jews.
