I can’t imagine you’re referring to the Catholic Church; they have famous sermons that were read from the pulpits (written by Pius XI) that warned of Nazism.
Hitler had no use for the Church (for the same reason the French revolutionaries and the Bolsheviks didn’t); it was a competing authority.
During the 1930s during the time the Nazis took power there were Nazi flags covering the alters of the churches in Germany as Bohnhoeffer reported and rejected. Stop kidding yourself.
