I am presently working through Mark Riebling’s Church of Spies: The Pope’s Secret War Against Hitler.
I found an interesting anecdote about what happened in Bavaria when the Nazis took Crucifixes out of schools.
In rural Bavaria, there were already flickers of revolt. When party bosses removed crucifixes from rural schools, pious women launched a wave of civil disobedience. Often they marched together to replace a crucifix after a Mass for a fallen soldier. In the village of Velburg, five hundred women pushed into the mayor’s house, pinned him down as he reached for his pistol, and forced his wife to hand over the classroom keys. Women rallied their husbands in other villages, where the public squares filled with peasants brandishing pitchforks. Perceiving “a front of psychological resistance” and “almost a revolutionary mood,” the Bavarian government restored the crosses. Unarmed women had faced down the world-conquering Nazis.
