The Catholic Bishop of Münster, Publicly Protested against The Persecution and against Action T4

In 1941 the Catholic Bishop of Münster, Clemens August Graf von Galen, publicly protested against the 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.
