CCC 1560

As Christ's vicar, each bishop has the pastoral care of the particular Church entrusted to him, but at the same time he bears collegially with all his brothers in the episcopacy the solicitude for all the Churches: "Though each bishop is the lawful pastor only of the portion of the flock entrusted to his care, as a legitimate successor of the apostles he is, by divine institution and precept, responsible with the other bishops for the apostolic mission of the Church."⁴¹ Pius XII, Fidei donum: AAS 49AAS — Acta Apostolicae Sedis (official gazette of the Holy See)Volume 49 (1957) at vatican.va — scanned PDF (1957) 237; cf.
