As legitimate successors of theApostles and members of the episcopal college, bishops should reahze that they are bound together and should manifest a concern for all the churches. For by divine institution and the rule of the apostolic office each one together rvith all the other bishops is responsible for the Church. They should especially be concemed about those parts of the world where the word of God has not yet been proclaimed or where the faithful, particularly because of the small number of priests, are in danger of departing from the precepts of the Christian life, and even of losing the faith itself. ...
Strive, moreover, to see to it that suitable sacred ministers as well as auxiliaries, both religious and lay, be prepared for the missions and other areas suffering from a lack of clergy. ...
Bishops should also be mindful, in administering ecclesiastical property, of the needs not only of their own dioceses but also of the other particular churches, for they are also a part of the one Church of Christ. (Chistus Dominus, 6)
