Бенедикт XV
Ad beatissimi Apostolorum (Appealing for Peace) is an encyclical of Pope Benedict XV given at St. Peter's, Rome, on the Feast of All Saints on November 1, 1914, in the first year of his Pontificate. The first encyclical written by Pope Benedict XV coincided with the beginning of the First World War, which he labelled "the Suicide of Civilized Europe".
