Redemptoris nostri cruciatus
Redemptoris nostri cruciatus (The passion of our Redeemer) is an encyclical of Pope Pius XII dated 15 April 1949 focusing on the situation in Palestine immediately following the cessation of fighting in the 1948 Arab–Israeli War. It was published shortly after the signing of armistice agreements between Arabs and Jews that brought the war to an end.
