98 Unity, towards which, so many, answerable for the destiny of nations, look with regretful yearning as they experience from day to day the vanity of the very means in which once they had placed their trust! Unity, the desired of those many legions of Our sons who daily call upon "The God of Peace and of love" (II Corinthians xiii. 11). Unity, the hope of so many noble minds separated from Us, who yet in their hunger and thirst for justice and peace turn their eyes to the See of Peter and from it await guidance and counsel!
