(CCC 193) None of the creeds from the different stages in the Church's life can be considered superseded or irrelevant. They help us today to attain and deepen the faith of all times by means of the different summaries made of it. Among all the creeds, two occupy a special place in the Church's life: (CCC 194) The Apostles' Creed is so called because it is rightly considered to be a faithful summary of the apostles' faith. It is the ancient baptismal symbol of the Church of Rome. Its great authority arises from this fact: it is "the Creed of the Roman Church, the See of Peter the first of the apostles, to which he brought the common faith" (St. Ambrose, Expl. symb. 7: PL 17, 1196). (CCC 195) The Niceno-Constantinopolitan or Nicene Creed draws its great authority from the fact that it stems from the first two ecumenical Councils (in 325 and 381). It remains common to all the great Churches of both East and West to this day. (CCC 196) Our presentation of the faith will follow the Apostles' Creed, which constitutes, as it were, "the oldest Roman catechism". The presentation will be completed however by constant references to the Nicene Creed, which is often more explicit and more detailed. (CCC 191) "These three parts are distinct although connected with one another. According to a comparison often used by the Fathers, we call them articles. Indeed, just as in our bodily members there are certain articulations which distinguish and separate them, so too in this profession of faith, the name articles has justly and rightly been given to the truths we must believe particularly and distinctly" (Roman Catechism, I, I, 4). In accordance with an ancient tradition, already attested to by St. Ambrose, it is also customary to reckon the articles of the Creed as twelve, thus symbolizing the fullness of the apostolic faith by the number of the apostles (Cf. St. Ambrose, Expl. symb. 8). (CCC 819) "Furthermore, many elements of sanctification and of truth" (LG 8 § 2) are found outside the visible confines of the Catholic Church: "the written Word of God; the life of grace; faith, hope, and charity, with the other interior gifts of the Holy Spirit, as well as visible elements" (UR 3 § 2; cf. LG 15). Christ's Spirit uses these Churches and ecclesial communities as means of salvation, whose power derives from the fullness of grace and truth that Christ has entrusted to the Catholic Church. All these blessings come from Christ and lead to him (Cf. UR 3), and are in themselves calls to "Catholic unity" (Cf. LG 8).
