21 Rather let us celebrate the ancient unity which bound Boniface, the first apostle of Germany, and the Germans themselves to the Holy See. His mission was the source of faith, of prosperity, and of civilization for the Germans. We could recall many other worthwhile details; but we have said enough - maybe even too much - for it is so well-known that a long speech filled with proof is not necessary. We enjoyed sharing these old memories with you in order to gather consolation to bear the present more courageously. We are strengthened by the hope of future unity and of attachment to the Church in "the fullness of peace and the bounds of charity."
