"We have begun to have hope, We are fostering it because its realization would be a great cause for joy, and, it is a fact, We are pursuing more strenuously this work so profitable for the salvation of many. Our goal is to discharge to the utmost degree whatever may be hoped for from the prudent direction of the Apostolic See. The reasons for rivalry and suspicion must be removed; then the fullest energies can be marshaled for reconciliation. We consider this of paramount importance to preserving the integrity proper to the discipline of the Eastern Churches. For Our part, We have ever rendered extreme attention and concern for this endeavor. In this vein, We have already given instructions for establishing schools to form young clerics of their nationalities. We shall give a like instruction for erecting other institutes. In them the students will cultivate their rites with the greatest devotion, observe them, and have full knowledge of their usages. In point of fact there is more importance than can be believed in preserving the Eastern rites. Their antiquity is august, it is what gives nobility to the different rites, it is a brilliant jewel for the whole Church, it confirms the God-given unity of the Catholic Faith."
-Pope Leo XIII, Orientalium Dignitas
