4 Now to consolidate this agreement, We think We should make three statements in particular in this letter. I. Concerning the rights, privileges, duties, and prerogatives of the patriarch, We wish that nothing be taken away from them nor be decreased; but at the same time, We strongly ask Our venerable brother, the patriarch of Antioch, to show a fitting respect for and to embrace with fraternal charity the bishops of his nation "whom the Holy Spirit has placed in charge of the Church of God," in conformity with the precept of St. Peter, the prince of the apostles: "Be not as masters among your people, but from the heart become an example for the flock."(1 Pr 5.3) That is also what the beautiful words of St. Bernard express: "May love accomplish more than power." II. We also remind all the bishops of the same nation that they owe homage and deference to the patriarch We have praised. They should show him the submission that is due him as their legitimate superior. If some controversy arises between them, they should humbly submit it first of all to the judgment of the patriarch. If it turns out that the question cannot be resolved, it should be respectfully referred to the Holy See. III. To prevent future contestations of rights, it would be most effective to convene a plenary Council. That is why, as We have already recommended to you on other occasions, We prescribe it for you now by this letter. The Council should be convened as soon as possible. The following matters should be discussed: the rights of the patriarch and of the bishops; the correct administration of the faithful; the discipline of the clergy, monastic orders, and other religious institutions; the needs of missions; the beauty of divine worship; the sacred liturgy; and other related matters which should be considered with prudent care to ensure the greater glory of God and to increase the honor of the Greek Melchite church. As the other Eastern churches have drawn great profit from the meeting of their national council in arranging their affairs and in restoring ecclesiastical discipline, so We can rightly promise magnificent results for your church from the composition and promulgation of written laws.
