What All Christians Believe In Common: Eastern Orthodox, Roman Catholics, and Protestants
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.” (quote from Saint Ambrose). (Catechism of the Catholic Church § 194.)
The Nicene-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. (Catechism of the Catholic Church §195)
The Athanasian Creed is a succinct summary of the doctrine of the Trinity and the Incarnation, making very clear by repeating statements in various ways the trinity of Persons in God, and the twofold nature in the one Divine Person of Jesus Christ.
