Mit brennender Sorge (German for "With burning anxiety") is a Catholic Church encyclical of Pope Pius XI, published on 10 March 1937 (but bearing a date of Passion Sunday, 14 March). Written in German, not the usual Latin, it was read from the pulpits of all German Catholic churches on one of the Church's busiest Sundays, (Palm Sunday). It condemned breaches of an agreement signed between the Nazi government and the Church, and included criticism of Nazi ideology and, in the interpretation of some scholars, of Nazism and Hitler.
