Mit brennender Sorge ( , in English "With deep [lit. 'burning'] anxiety") is an encyclical of Pope Pius XI, issued on 10 March 1937 (but bearing a date of Passion Sunday, 14 March)."Church and state through the centuries", Sidney Z. Ehler & John B Morrall, pp. 518–519, org pub 1954, reissued 1988, Biblo & Tannen, 1988, Written in German, not in the usual Latin, it was smuggled into Nazi Germany for fear of censorship and was read from the pulpits of all German Catholic churches on one of the Church's busiest Sundays, Palm Sunday (21 March that year).Anton Gill; An Honourable Defeat; A History of the German Resistance to Hitler; Heinemann; London; 1994; p. 58"Before 1931 all such messages [encyclicals] were written in Latin. The encyclical Non abbiamo bisogno of June 29, 1931, which condemned certain theories and practices of Italian Fascism, particularly in the realm of education, and denounced certain treaty violations of Signor Mussolini's Government, was the first document of that kind that appeared in a language other than Latin." The Catholic Herald, "First Encyclical in German", p. 3, 9 April 1937

The encyclical condemned breaches of the 1933 Reichskonkordat agreement signed between the German Reich and the Holy See.Robert A. Ventresca – p.iv of photos, Soldier of Christ It condemned "pantheistic confusion", "neopaganism", "the so-called myth of race and blood", and the idolizing of the State. It contained a vigorous defense of the Old Testament with the belief that it prepares the way for the New.Paul O'Shea, A Cross too Heavy, pp. 156–157 The encyclical states that race is a fundamental value of the human community which is necessary and honorable, but condemns the exaltation of race, or the people, or the state, above their standard value to an idolatrous level.Martin Rhonheimer, "The Holocaust: What Was Not Said", First Things 137 (November 2003): 18–28 The encyclical declares "that man as a person possesses rights he holds from God, and which any collectivity must protect against denial, suppression or neglect."Mit brennnder Sorge, § 30 in English version National Socialism, Adolf Hitler and the Nazi Party are not named in the document. The German term (government of the Reich) is used to refer to the Nazi regime.Mit brennender Sorge Para 3

The effort to produce and distribute over 300,000 copies of the letter was entirely secret, allowing priests across Germany to read the letter without interference.The Roman Catholic periodical The Tablet reported at the time "The Encyclical, which took the Nazi Government completely unawares, had been introduced into Germany by the diplomatic bag to the Nunciature, and Monsignor Orsenigo, Apostolic Nuncio in Berlin had arranged for its secret distribution all over the country so that it was read in every Catholic church of the Reich last Sunday, before the Government had time to confiscate and suppress it.", The Tablet, 3 April 1937, p. 10 The Gestapo raided the churches the next day to confiscate all the copies they could find, and the presses that had printed the letter were closed. According to historian Ian Kershaw, an intensification of the general anti-church struggle began around April in response to the encyclical.Ian Kershaw, Hitler a Biography; 2008 Edn; W.W. Norton & Company; London; pp. 381–382 Klaus Scholder wrote: "state officials and the Party reacted with anger and disapproval. Nevertheless the great reprisal that was feared did not come. The concordat remained in force and despite everything the intensification of the battle against the two churches which then began remained within ordinary limits."Scholder, pp. 154–155 The regime further constrained the actions of the Church and harassed monks with staged prosecutions for alleged immorality and phony abuse trials.The Catholic periodical The Tablet reported shortly after the issuing of the encyclical "The case in the Berlin court against three priests and five Catholic laymen is, in public opinion, the Reich's answer to the Pope's Mit brennender Sorge encyclical, as the prisoners have been in concentration camps for over a year. Chaplain Rossaint of Dusseldorf is, however, known as a pacifist and an opponent of the National Socialist regime, and it is not denied that he was indiscreet; but he is, moreover, accused of having tried to form a Catholic-Communist front on the plea that he baptized a Jewish Communist. This the accused denies, and his defence has been supported by Communist witnesses", The Tablet, p. 13, 24 April 1937 Though Hitler is not named in the encyclical, the German text does refer to a "Wahnprophet", which some have interpreted as meaning "mad prophet" and as referring to Hitler himself.McGonigle, p. 172: "the encyclical Mit brennender Sorge was read in Catholic Churches in Germany. In effect it taught that the racial ideas of the leader (Führer) and totalitarianism stood in opposition to the Catholic faith; Bokenkotter, pp. 389–392; Historian Michael Phayer wrote that the encyclical doesn't condemn Hitler or National Socialism, "as some have erroneously asserted" (Phayer, 2002), p. 2; "His encyclical Mit brennender Sorge was the 'first great official public document to dare to confront and criticize Nazism' and even described the Führer himself as a 'mad prophet possessed of repulsive arrogance.'"; Rhodes, pp. 204–205: "Mit brennender Sorge did not prevaricate … Nor was the Führer himself spared, for his 'aspirations to divinity', 'placing himself on the same level as Christ': 'a mad prophet possessed of repulsive arrogance' (widerliche Hochmut)."; "It was not the case that Pius failed to "spare the Führer," or called him a "mad prophet possessed of repulsive arrogance." The text limits its critique of arrogance to unnamed Nazi "reformers" (John Connelly, Harvard University Press, 2012, "From Enemy to Brother: The Revolution in Catholic Teaching on the Jews, 1933–1965", p. 315, fn 52)

It was reported at the time that the encyclical was paired and somewhat overshadowed by the anti-communist encyclical Divini Redemptoris of 19 March, in order to avoid the charge that the Pope was indirectly favoring communism.The Catholic Herald, "The Church And Germany", p. 8, 16 April 1937

Background

Following the Nazi takeover, the Catholic Church hierarchy in Germany initially attempted to co-operate with the new government, but by 1937 had become highly disillusioned. A threatening, though initially mainly sporadic persecution of the Catholic Church followed the Nazi takeover.Ian Kershaw; Hitler a Biography; 2008 Edn; W.W. Norton & Company; London; p. 332 Hitler moved quickly to eliminate Political Catholicism. Two thousand functionaries of the Bavarian People's Party were rounded up by police in late June 1933. They along with the national Catholic Centre Party, ceased to exist in early July, as the Nazi Party became the only legally permitted party (Gleichschaltung) in the country. Vice Chancellor Franz von Papen meanwhile negotiated the Reichskonkordat treaty with the Vatican, which prohibited clergy from participating in politics.Ian Kershaw; Hitler a Biography; 2008 Edn; W.W. Norton & Company; London; p. 290 Kershaw wrote that the Vatican was anxious to reach agreement with the new government, despite "continuing molestation of Catholic clergy, and other outrages committed by Nazi radicals against the Church and its organisations".Ian Kershaw; Hitler a Biography; 2008 Edn; W.W. Norton & Company; London; p. 295

The Reichskonkordat () was signed on 20 July 1933 between the Holy See and Nazi Germany. According to historian Pinchas Lapide, the Nazis saw the treaty as giving them moral legitimacy and prestige, whilst the Catholic Church sought to protect itself from persecution through a signed agreement.Pinchas Lapide: Three Popes and the Jews. 1967, Hawthorn Press, p. 102 According to Guenter Lewy, a common view within Church circles at the time was that Nazism would not last long, and the favorable Concordat terms would outlive the current regime (the Concordat does remain in force today).Lewy, 1964, p. 92 A Church handbook published with the recommendation of the entire German Church episcopate described the Concordat as "proof that two powers, totalitarian in their character, can find an agreement, if their domains are separate and if overlaps in jurisdiction become parallel or in a friendly manner lead them to make common cause".Lewy, 1964, p. 93 Lewy wrote "The harmonious co-operation anticipated at the time did not quite materialize" but that the reasons for this "lay less in the lack of readiness of the Church than in the short sighted policies of the Hitler regime."

In Mit brennender Sorge, Pope Pius XI said that the Holy See had signed the Concordat "in spite of many serious misgivings" and in the hope it might "safeguard the liberty of the church in her mission of salvation in Germany". The treaty comprised 34 articles and a supplementary protocol. Article 1 guaranteed "freedom of profession and public practice of the Catholic religion" and acknowledged the right of the church to regulate its own affairs. Within three months of the signing of the document, Cardinal Bertram, head of the German Catholic Bishops' Conference, was writing in a pastoral letter of "grievous and gnawing anxiety" with regard to the government's actions towards Catholic organisations, charitable institutions, youth groups, press, Catholic Action, and the mistreatment of Catholics for their political beliefs.The Nazi War Against the Catholic Church; National Catholic Welfare Conference; Washington D.C.; 1942 According to Paul O'Shea, Hitler had a "blatant disregard" for the Concordat, and its signing was to him merely a first step in the "gradual suppression of the Catholic Church in Germany".Paul O'Shea; A Cross Too Heavy; Rosenberg Publishing; pp. 234–35; Anton Gill wrote that "with his usual irresistible, bullying technique, Hitler then proceeded to take a mile where he had been given an inch" and closed all Catholic institutions whose functions weren't strictly religious:

Following the signing of the document, the formerly outspoken nature of opposition by German Catholic leaders towards the Nazi movement weakened considerably.Joachim Fest; Plotting Hitler's Death: The German Resistance to Hitler 1933–1945; Weidenfeld & Nicolson; London; p. 31 But violations of the Concordat by the Nazis began almost immediately and were to continue such that Falconi described the Concordat with Germany as "a complete failure".Falconi, 1967, p. 227

The Concordat, wrote William Shirer, "was hardly put to paper before it was being broken by the Nazi Government". The Nazis had promulgated their sterilization law, an offensive policy in the eyes of the Catholic Church, on 14 July. On 30 July, moves began to dissolve the Catholic Youth League. Clergy, nuns and lay leaders were to be targeted, leading to thousands of arrests over the ensuing years, often on trumped-up charges of currency smuggling or "immorality".William L. Shirer; The Rise and Fall of the Third Reich; Secker & Warburg; London; 1960; pp. 234–35 Historian of the German Resistance Peter Hoffmann wrote that, following the Nazi takeover:

In August 1936 the German episcopate had asked Pius XI for an encyclical that would deal with the current situation of the Church in Germany.Lewy, 1967, p. 228 In November 1936 Hitler had a meeting with Cardinal Faulhaber during which he indicated that more pressure would be put on the Church unless it collaborated more zealously with the regime.Falconi, 1967, p. 228 On 21 December 1936 the Pope invited, via Cardinal Pacelli, senior members of the German episcopate to Rome. On 16 January 1937 five German prelates and Cardinal Pacelli agreed unanimously that the time had now come for public action by the Holy See. Pope Pius XI was gravely ill but he too was convinced of the need to publish an encyclical about the Church in Germany as soon as possible.Falconi, 1967, p. 229
