174. Why is the Church apostolic?

(Comp 174) The Church is apostolic in her origin because she has been built on “the foundation of the Apostles” (Ephesians 2:20). She is apostolic in her teaching which is the same as that of the Apostles. She is apostolic by reason of her structure insofar as she is taught, sanctified, and guided until Christ returns by the Apostles through their successors who are the bishops in communion with the successor of Peter.

“In brief”

(CCC 869) 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.

To deepen and explain

(CCC 857) The Church is apostolic because she is founded on the apostles, in three ways: - she was and remains built on "the foundation of the Apostles" (Eph 2:20; Rev 21:14); the witnesses chosen and sent on mission by Christ himself (Cf. Mt 28:16-20; Acts 1:8; 1 Cor 9:1; 15:7-8; Gal 1:1; etc.); - with the help of the Spirit dwelling in her, the Church keeps and hands on the teaching (Cf. Acts 2:42), the "good deposit," the salutary words she has heard from the apostles (Cf. 2 Tim 1:13-14); - she continues to be taught, sanctified, and guided by the apostles until Christ's return, through their successors in pastoral office: the college of bishops, "assisted by priests, in union with the successor of Peter, the Church's supreme pastor" (AG 5): You are the eternal Shepherd who never leaves his flock untended. Through the apostles you watch over us and protect us always. You made them shepherds of the flock to share in the work of your Son…. (Roman Missal, Preface of the Apostles I).

On reflection

(CCC 171) The Church, "the pillar and bulwark of the truth", faithfully guards "the faith which was once for all delivered to the saints". She guards the memory of Christ's words; it is she who from generation to generation hands on the apostles' confession of faith (I Tim 3:15; Jude 3). As a mother who teaches her children to speak and so to understand and communicate, the Church our Mother teaches us the language of faith in order to introduce us to the understanding and the life of faith. (CCC 1575) Christ himself chose the apostles and gave them a share in his mission and authority. Raised to the Father's right hand, he has not forsaken his flock but he keeps it under his constant protection through the apostles, and guides it still through these same pastors who continue his work today (Cf. Roman Missal, Preface of the Apostles I). Thus, it is Christ whose gift it is that some be apostles, others pastors. He continues to act through the bishops (Cf. LG 21; Eph 4:11).
