Martin Niemöller and other Protestant pastors formed the Pastors’ Emergency League (Pfarrernotbund) to oppose the imposition of the Nazi “Aryan paragraph” and related efforts to align Protestant churches with National Socialism—an important precursor to the Confessing Church.
Representatives of the emerging Confessing Church movement adopted the Barmen Declaration, rejecting attempts to subordinate Christian doctrine to Nazi racial ideology and state control—becoming a foundational statement of Protestant church opposition in Germany.
At the Second Confessing Synod in Berlin-Dahlem, Confessing Church delegates declared the official constitution of the German Evangelical Church effectively destroyed and established new emergency leadership structures—formalizing institutional resistance to the Nazi-aligned church hierarchy.
Pope Pius XI promulgated Mit brennender Sorge (“With Burning Concern”), condemning core elements of Nazi ideology (including neopaganism and the absolutizing of race and state) and criticizing violations of the 1933 Reich Concordat.
The encyclical Mit brennender Sorge was clandestinely distributed and then read from pulpits across Germany on Palm Sunday, making it one of the most prominent coordinated Catholic public challenges to the Nazi regime’s church policy.
The Gestapo arrested Protestant pastor Martin Niemöller, a leading figure in the Confessing Church; after conviction and completion of a sentence, he was placed in “protective custody” and sent to concentration camps—an emblematic case of repression of church opposition.
Pope Pius XII released his first encyclical, Summi Pontificatus, criticizing totalitarian conceptions of the state and emphasizing the unity of human society—widely read at the time as a challenge to ideologies of racism and state absolutism.
Catholic Bishop Clemens August Graf von Galen publicly condemned killings of the disabled associated with the Nazi “euthanasia” program in a major sermon in Münster, helping galvanize wider church-based opposition to Aktion T4.
Hitler ordered the official suspension of Aktion T4. While killings continued in other forms, the order is closely associated with mounting domestic protests, including outspoken opposition from prominent church leaders.
Berlin priest Bernhard Lichtenberg was arrested by Nazi authorities amid his continued public prayers for Jews and criticism of persecution, illustrating Catholic clerical resistance that directly confronted state policy despite severe personal risk.
Members of the White Rose—a resistance circle that included deeply Christian ethical motivations—were arrested after distributing anti-Nazi leaflets at the University of Munich, highlighting religiously inflected moral opposition among German youth.
Following a rapid trial, Hans and Sophie Scholl (and Christoph Probst) were executed, turning the White Rose into a lasting symbol of conscience-driven opposition to Nazi rule, including opposition rooted in Christian belief and ethics.
Lutheran pastor and theologian Dietrich Bonhoeffer, associated with the Confessing Church and broader anti-Nazi resistance networks, was arrested and imprisoned—removing a major religious voice opposing Nazism from public life.
After imprisonment, Bernhard Lichtenberg died while being transported under Nazi custody toward Dachau concentration camp, becoming a prominent Catholic martyr figure associated with opposition to Nazi persecution policies.
Dietrich Bonhoeffer was executed by hanging at Flossenbürg after a summary SS proceeding, one of the most internationally recognized cases of a church-linked resister killed by the Nazi regime in the war’s final weeks.
