“Secret history” is an admission of official neutrality

Despite efforts to protect its rights within Germany under a 1933 Reichskonkordat treaty, the Church in Germany had faced persecution in the years since Adolf Hitler had seized power, and Pope Pius XI accused the Nazi government of sowing ‘fundamental hostility to Christ and his Church’. Pius XII became Pope on the eve of war and lobbied world leaders to prevent the outbreak of conflict. His first encyclical, Summi Pontificatus, called the invasion of Poland an “hour of darkness”. He affirmed the policy of Vatican neutrality, but maintained links to the German Resistance.
To the credit of the Catholic Church, the Italians under Mussolini were not the racist murderers that the Germans were, under Hitler. And, the few who joined in the plot against Hitler were mostly Catholics. Let us never confuse fascism with Naziism. One is merely wrong and the other is evil.
While I appreciate the difference between being merely wrong and being evil, I do not at all appreciate being lectured by Pope Francis on matters of science and economics.
You think Catholics secretly plotting to kill Hitler is neutrality?
Do you think they should have first "officially" announced their plans?
Did "neutral" Japan officialy declare war on the United States before it bombed Pearl Harbor?
