CCC 880

When Christ instituted the Twelve, "he constituted [them] in the form of a college or permanent assembly, at the head of which he placed Peter, chosen from among them."³⁹⁸ LG 19; cf. Lk 6:13; Jn 21:15-17. Just as "by the Lord's institution, St. Peter and the rest of the apostles constitute a single apostolic college, so in like fashion the Roman Pontiff, Peter's successor, and the bishops, the successors of the apostles, are related with and united to one another."³⁹⁹ LG 22; cf. CIC, can. 330.
