As part of the campaign against the Catholic Church, hundreds of monasteries in Germany and Austria were confiscated by the Gestapo and their occupants were expelled. In 1941 the Catholic Bishop of Münster, Clemens August Graf von Galen, publicly protested against this persecution and against Action T4, the Nazi involuntary euthanasia programme under which the mentally ill, physically deformed, and incurably sick were to be killed. In a series of sermons that received international attention, he criticised the programme as illegal and immoral. His sermons led to a widespread protest movement among church leaders, the strongest protest against a Nazi policy up until that point. Bormann and others called for Galen to be hanged, but Hitler and Goebbels concluded that Galen's death would only be viewed as a martyrdom and lead to further unrest. Hitler decided to deal with the issue when the war was over.
