The pressures on these young clergy were immense. At the 1934 Dahlem synod, the Confessing Church had decided to train, certify, and ordain its own clergy. Bonhoeffer’s seminary at Finkenwalde was one five Confessing Church seminaries. In August 1937, however, Heinrich Himmler banned these seminaries, and the Gestapo closed Finkenwalde and the other seminaries one month later. The Confessing Church continued to examine and ordain its own candidates, but its examination commission in Berlin was arrested and tried in 1941.
