111 Whatever We can do to hasten the day when the dove of peace may find on this earth, submerged in a deluge of discord, somewhere to alight, We shall continue to do, trusting in those statesmen, who before the outbreak of war, nobly toiled to avert such a scourge from the peoples; trusting in the millions of souls of all countries and of every sphere, who call not for justice alone but for love and mercy; above all, trusting in God Almighty to Whom We daily address the prayer: "in the shadow of thy wings will I hope, until iniquity pass away" ( Psalm lvi. 2).
