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, 
     born of the Virgin Mary,
  He suffered under Pontius Pilate, 
     was crucified, died, and was buried
  He descended to the dead,
  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 Apostles' Creed, a variation of the earlier 'Roman Creed' (AD 150), was said by Church tradition to have been composed jointly by the Twelve Apostles in Jerusalem. While there is some doubt as to whether each Apostle contributed a distinct element to the teaching, the creed was used by the early church and often divided into doctrinal questions asked to candidates for baptism.

I believe in one God,
  the Father, the Almighty,
  Maker of heaven and earth,
  of all things seen and unseen.
I beleive in one Lord, Jesus Christ, 
  the only Son of God,
  eternally begotten of his Father,
  God of God, Light of 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 and was buried.
   On the third day he rose again 
     in fulfillment of the Scriptures; 
   He ascended into heaven, 
      and seated at the right hand of the Father.
He will come again in glory to judge the living and the dead, 
   and his kingdom shall have no end.
I 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 worshiped and glorified.
   He has spoken through the prophets.
   We believe 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. 

The Nicene Creed was a product of the Council of Constantinople convened in that city in AD 381 by the Eastern Emperor Theodosius. The Arian heresy of the fourth century denied the nature of the Trinity, claiming that God the Father alone was 'God.'

The words of the Nicene Creed emphasize the unity and equality of the Father, Son and Holy Spirit, while containing elements of the earlier Apostles' Creed.
