Domingo de Pasión
Mit brennender Sorge ( , "With burning concern") "On the Church and the German Reich" is an encyclical of Pope Pius XI, issued during the Nazi era on 10 March 1937 (but bearing a date of Passion Sunday, 14 March). Written in German, not the usual Latin, it was smuggled into 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).
