Creed: The Basic Profession of Faith
From its earliest days, the Church used brief summaries to describe an outline of its most essential beliefs. These summaries are called "creeds", from the Latin credo, meaning "I believe." They are also called "professions of faith," since they summarize the faith that Christians profess. The Catholic Church uses two very old creeds regularly as a part of its liturgy and other prayers. There are a number of other Catholic creeds as well. The older Apostles Creed is brief and simple. It is considered to be a faithful summary of the Apostles' teaching. It is the ancient baptismal symbol of the Church at Rome. (See Catechism, 194.) The longer Catholic Nicene Creed contains some additional language explaining our belief in the Trinity. Another ancient & traditional creed is commonly called the Athanasian Creed, since it was originally attributed to St. Athanasius, who died in 373 A.D. (This creed is no longer officially attributed to him.) It is also called the Quicumque vult, after its first words in Latin. This beautiful creed contains a detailed meditation on the nature of the Trinity.
 

The Apostles' Creed ~ Considered to be a faithful summary of the Apostles' teaching. It is the ancient baptismal symbol of the Church at Rome.

I believe in God, the Father almighty, creator of heaven and earth.
I believe in Jesus Christ, his only Son, our Lord.
He was conceived by the power of the Holy Spirit and born of the Virgin Mary.
He suffered under Pontius Pilate, was crucified, died, and was buried.
He descended into hell. On the third day he rose again.
He ascended into heaven and is seated at the right hand of the Father.
He will come again to judge the living and the dead.
I believe in the Holy Spirit, the holy Catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting.
Amen.
 

The Nicene Creed ~ The most ecumenical of creeds, it is the most widely accepted and used brief statements of the Christian Faith. In liturgical churches, it is said every Sunday as part of the Liturgy. It is Common Ground to East Orthodox, Roman Catholics, Anglicans, Lutherans, Calvinists, and many other Christian groups. Many groups that do not have a tradition of using it in their services nevertheless are committed to the doctrines it teaches.

We believe in one God, the Father, the Almighty,
maker of heaven and earth, and of all that is, seen and unseen.
We believe in one Lord, Jesus Christ, the only Son of God,
eternally begotten of the Father, God from God, Light from Light,
true God from true God, begotten, not made, one in Being with the Father.
Through him all things were made.
For us men and for our salvation, he came down from heaven:
by the power of the Holy Spirit he was born of the Virgin Mary, and became man.
For our sake he was crucified under Pontius Pilate; he suffered, died, and was buried.
On the third day he rose again in fulfillment of the Scriptures;
he ascended into heaven and is seated at the right hand of the Father.
He will come again in glory to judge the living and the dead,
and his kingdom will have no end.
We believe in the Holy Spirit, the Lord, the giver of life,
who proceeds from the Father and the Son.
With the Father and the Son he is worshipped and glorified.
He has spoken through the Prophets.
We believe in one holy catholic and apostolic Church.
We acknowledge one baptism for the forgiveness of sins.
We look for the resurrection of the dead, and the life of the world to come.
Amen.
