CCC 193 None of the creeds from the different stages in the Church’s life can be considered superseded or irrelevant.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”.1
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.
