particular, the questions of denominational schools and pastoral work in the armed forces prevented any agreement on the national level, despite talks in the winter of 1932. Adolf Hitler was appointed Chancellor on 30 January 1933 and sought to gain international respectability and to remove internal opposition by representatives of the church and the Catholic Centre Party. He sent his vice chancellor Franz von Papen, a Catholic nobleman, to Rome to offer negotiations about a Reichskonkordat. On behalf of Pacelli, Prelate Ludwig Kaas, the outgoing chairman of the Centre Party, negotiated first drafts of the terms with Papen. The concordat was finally signed, by Pacelli for the Vatican and von Papen for Germany, on 20 July and ratified on 10 September 1933. Bishop Preysing cautioned against compromise with the new regime, against those who saw the Nazi persecution of the church as an aberration that Hitler would correct. Between 1933 and 1939, Pacelli issued 55 protests of violations of the Reichskonkordat. Most notably, early in 1937, Pacelli asked several German cardinals, including Cardinal Michael von Faulhaber, to help him write a protest of Nazi violations of the Reichskonkordat; this was to become Pius XI's 1937 encyclical, Mit brennender Sorge. The encyclical was written in German and not the usual Latin of official Catholic Church documents. Secretly distributed by an army of motorcyclists and read from every German Catholic Church pulpit on Palm Sunday, it condemned the paganism of the National Socialism ideology. Pius XI credited its creation and writing to Pacelli. It was the first official denunciation of Nazism made by any major organization and resulted in persecution of the church by the infuriated Nazis who closed all the participating presses and "took numerous vindictive measures against the Church, including staging a long series of immorality trials of the Catholic clergy". On 10 June 1941, the pope commented on the problems of the Reichskonkordat in a letter to the Bishop of Passau, in Bavaria: "The history of the Reichskonkordat shows, that the other side lacked the most basic prerequisites to accept minimal freedoms and rights of the Church, without which the Church simply cannot live and operate, formal agreements notwithstanding". Relations with the media Cardinal Pacelli gave a lecture entitled "La Presse et L'Apostolat" at the Pontifical University of St. Thomas Aquinas, Angelicum on 17 April 1936.
