Catholic Answerfrom The Ignatius Catholic Study Bible, 2nd Edition, RSV Note for Matthew 16:19:the keys: A symbol of teaching authority (Luke 11:52). Jesus consecrates Peter as the Church's chief teacher, whose office will continue on through successors. the plural use of keysmay imply a connection with the "gates" in 16:18 and mean that Peter's position includes, among other things, the authority to release the righteous souls who are detained in Hades but destined for heaven. In the O[ld] T[estament] Davidic empire, the king appointed a cabinet of ministers for specific tasks in the kingdom (1 Kings 4:1-6; 2 Kings 18:37). Of these, a prime minister was elevated to unique status of authority, ranking second only to the king. This government structure was common among kingdoms in the ancient Near East (cf. Gen 41:39-43; Esther 3:1-2). Jesus here evokes Is 22:15-25, where the prime minister's office is handed on to a successor by the symbolic act of handing on the "key of the house [i.e., kingdom] of David" (Is 22:22). In Matthew, Jesus is the new Davidic king, who appoints Peter the prime minister over the kingdom of heaven (emphasis in original) in the Church. As in Is 22, Peter's position is designed for him and his successors; the office is meant to endure as long as the kingdom itself. Entrusted with the keys, Peter wields Christ's own royal authority (cf. Rev 1:18; 3:7).
