I believe in One God

the Father Almighty,
creator of heaven and earth, of all things visible and invisible.

And in one Lord Jesus Christ, Son of God, the only-begotten ,
born of the Father before all ages.

Light of Light, true God of true God, begotten, not made, one in essence with the Father,
through Whom all things were made.
For us and for our salvation, he came down from heaven,
and was incarnate from the Holy Spirit and the Virgin Mary, and became man.
He was crucified for us under Pontius Pilate, and suffered, and was buried.

He rose on the third day, according to the Scriptures.
He ascended into heaven, and is seated at the right hand of the Father,
and He is coming again with glory, to judge the living and the dead,
and of His kingdom will have no end.

And in the Holy Spirit, the Lord, and Creator of Life,
Who proceeds from the Father,
Together with the Father and the Son
He is worshiped and glorified;
He spoke through the prophets.

In one, holy, catholic, and apostolic Church.
I profess one baptism for the remission of sins.
I expect the resurrection of the dead
and the life of the world to come. Amen.

Our Symbol of Faith is a proclamation of all that we believe and profess.   In our Byzantine Liturgy (St. John Chrysostum or St. Basil the Great), we chant the Creed to proclaim what we believe.   The Nicene Creed is our symbol of faith.   It is named after the Council of Nicea. 

The Nicene Creed draws its formation from the first two ecumenical Councils (325 and  381 A.D.). The first part of the Creed was written during the First Ecumenical Council held in Nicea, Asia Minor, in A.D. 325.  The second part of the Creed — I believe in the Holy Spirit — was written during the Second Ecumenical Council held in Constantinople in A.D. 381.   A number of renowned Eastern saints were present at the first Council in 325.  These included: Athanasius the Great; Nicholas of Myra; Spyridon of Trimythous; Alexander of Alexandria, and Paphnutius of Egypt, along with Constantine the Great who convened the Council.
