4 Another purpose of the celebrations is to perfect the present and to reestablish religious unity and peace for the future. These are the greatest goods and they come only from Christ who charged the Church with preserving, spreading, and defending Christian faith and charity. Thus, it is necessary for the Apostolic See to be united with the faithful. Boniface was the perfect herald and the model of such unity. This led to close, friendly relationships between the Roman See and your nation. While celebrating this unity and this perfect accord, we fervently desire to see them reestablished among all peoples so that "Christ might be all in all."
