CCC 869
Profession of Faith›SECTION TWO I. THE CREEDS›CHAPTER THREE I BELIEVE IN THE HOLY SPIRIT›Paragraph 3. THE CHURCH IS ONE, HOLY, CATHOLIC, AND APOSTOLIC
The Church is apostolic. She is built on a lasting foundation: "the twelve apostles of the Lamb" ( Rev 21:14). She is indestructible (cf Mt 16:18). She is upheld infallibly in the truth: Christ governs her through Peter and the other apostles, who are present in their successors, the Pope and the college of bishops.
