4 When war was declared, without abandoning the attitude of impartiality which was imposed by Our apostolic duty, which places Us above the conflicts which agitate human society, We did not fail to do Our utmost, in the measure which depended upon Us, and according to the possibilities offered to Us, for the triumph of justice and peace in Palestine and for the respect and protection of the Holy Places.
