This creed, probably based on that of Cyril of Jerusalem, with the addition of clauses from the Creed of Nicea, was approved by the Council of Chalcedon in 451 as representing the creed of the Councils of Nicea (325) and Constantinople (381). It is therefore sometimes called the Nicaeno-Constantinoplitan Creed. Today, it is commonly known as the "Nicene Creed."
The Nicene Creed is one of the most widely accepted and used concise statements of the Christian Faith. In liturgical churches, it is said every Sunday as part of the Liturgy that leads to the celebration of communion or the Lord's supper or the eucharist (meaning "thanksgiving"). It is common ground to Easterm 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.
I believe in one God, the Father Almighty,
Maker of heaven and earth,
and of all things visible and invisible.
And in one Lord Jesus Christ,
the only begotten Son of God,
begotten of His Father before all worlds,
God of God, Light of Light, very God of very God,
begotten, not made,
being of one substance with the Father,
by whom all things were made:
who, for us men and for our salvation,
came down from heaven,
and was incarnate by the Holy Ghost of the virgin Mary,
and was made man;
and was crucified also for us under Pontius Pilate.
He suffered and was buried;
and the third day He rose again according to the Scriptures,
and ascended into heaven,
and sitteth on the right hand of the Father.
And He shall come again with glory to judge both the quick and the dead:
whose kingdom shall have no end.
And I believe in the Holy Ghost,
the Lord and Giver of life,
who proceedeth from the Father and the Son,
who with the Father and the Son together is worshiped and glorified,
who spake by the prophets.
And I believe in one holy catholic and apostolic Church.
I acknowledge one baptism for the remission of sins;
and I look for the resurrection of the dead,
and the life of the world to come.
Amen.
Athanasian Creed
