On July 4, 1944, the following circular letter was sent by Prof. Karl Barth, Prof. Emil Brunner, Dr. W.A. Visser 't Hooft and Rev. Paul Vogt to pastors in Switzerland: "We send to you, enclosed, two messages from Hungary and a covering letter dated June 19, 1944, which came from reliable sources and reached Switzerland through diplomatic channels. The messages have shocked us deeply. Out of a sense of responsibility we feel it our duty to convey these messages to you. We do not doubt that you will read them and let them circulate within your own group. They are also known to the competent authorities." [496] There followed a wave of public protests. We quote some of them. [497] <223> On July 9, 1946, the Church Council of the Canton Zurich urged that the following message be read from every pulpit: "The present day truly has revealed enough frightful things, but in the last weeks one piece of news has reached us which far exceeds anything that we have heard for years. Reliable witnesses inform us of terrible persecution of the Jews in Hungary. In a few weeks between three and four hundred thousand people have been sacrificed, and who knows how many more there will be. Many are dying of exhaustion or hunger, but the majority meet their death by gas. In one single place, at Birkenau, four crematoria are in use, in which every day six thousand people can be gassed and burned and incinerated. Hitherto Hungary had more than a million Jews. A number of towns already have been cleared of Jews. Persecution is said to be impending in the capital, if it has not already begun. We do not know what can have induced the government to take these dreadful measures and at whose door the responsibility for this dreadful deed must lie. What can we do? It is not for us to pass self-righteous judgment on the acts of other peoples, for we are not guilt-free. It does not lie in our power to order the cessation of atrocities. The Swiss Protestant Church Federation addressed an urgent request to the Federal Council and to the International Red Cross that they would do everything possible to rescue the Jews still living in Hungary. We invite congregations to make solemn intercession for all those who must tread this dark road simply because they belong to another race. Let us also pray for our sister-Evangelical Church in Hungary, that strength and guidance be granted to her at a time when her people is taking upon itself such a terrible load of guilt. Let the word of the Psalmist be our prayer: 'Keep not Thou silence, O God: hold not Thy peace, and be not still, O God'." [498]
