Career
He held a seat in the Württemberg State Parliament (German: Landtag) until 1920. As a young man Wurm was a prison chaplain, and became a parish pastor when he was 45. Like many churchmen, he initially favored the Nazi regime, but its church policy soon moved him into opposition.
In September 1934 Wurm was deposed from his bishopric by Reich"s bishop Ludwig Müller because of his views on church policy (including) the Barmen Declaration, and was placed under house arrest twice.
These extreme measures were eventually rescinded by Hitler in the wake of protests and the stripping of power from Müller. Wurm then held the office of bishop until 1948.
Nevertheless, he was not politically apathetic and made numerous complaints to the Nazi party and the Nazi state. After the start of the war, he protested the murders of psychiatric patients under the Nazi euthanasia program
Wurm and the Catholic Bishop of Munster, August von Galen were able to lead widespread public opposition to the murder of invalids.
This earned him a 1944 ban against public speaking and writing. He associated with the resistance movements that centered on Carl Goerdeler and Ludwig Beck. He was a signatory of the October 1945 Stuttgart Declaration of Guilt.
