Bishop von Preysing's Cathedral Administrator, Fr Bernhard Lichtenberg, met his demise for protesting directly to Dr Conti, the Nazi State Medical Director. On 28 August 1941, he endorsed Galen's sermons in a letter to Conti, pointing to the German constitution which defined euthanasia as an act of murder. He was arrested soon after and later died en route to Dachau. Hitler wanted to have Galen removed, but Goebbels told him this would result in the loss of the loyalty of Westphalia. The regional Nazi leader and Hitler's deputy Martin Bormann called for Galen to be hanged, but Hitler and Goebbels urged a delay in retribution till war's end. In a 1942 Table Talk Hitler reportedly said: "The fact that I remain silent in public over Church affairs is not in the least misunderstood by the sly foxes of the Catholic Church, and I am quite sure that a man like Bishop von Galen knows full well that after the war I shall extract retribution to the last farthing." With the programme now public knowledge, nurses and staff (particularly in Catholics institutions) increasingly sought to obstruct implementation of the policy. Under pressure from growing protests, Hitler halted the main euthanasia program on 24 August 1941, though less systematic murder of the handicapped continued. The techniques learnt from the Nazi euthanasia program were later transferred for use in the Holocaust genocide. In the United States, the National Catholic Welfare Conference reported that the German Catholic bishops jointly expressed their "horror" at the policy in their 1942 Pastoral Letter:  In 1943, Pope Pius XII issued the encyclical "Mystici corporis Christi", in which he condemned the practice of killing the disabled. He stated his "profound grief" at the murder of the deformed, the insane, and those suffering from hereditary disease... as though they were a useless burden to Society," in condemnation of the ongoing Nazi euthanasia program. The Encyclical was followed, on 26 September 1943, by an open condemnation from the German Bishops which, from every German pulpit, denounced the killing of "innocent and defenceless mentally handicapped, incurably infirm and fatally wounded, innocent hostages, and disarmed prisoners of war and criminal offenders, people of a foreign race or descent." Paragraph 94 of "Mystici corporis Christi" reads:
