The earliest written version of the creed is perhaps the Interrogatory Creed of Hippolytus (c. A.D. 215).
Early Version
WE BELIEVE in God almighty [the Father almighty—(Rufinus)]
And in Christ Jesus, his only Son, our Lord
Who was born of the Holy Spirit and the Virgin Mary
Who was crucified under Pontius Pilate and was buried
And the third day rose from the dead
Who ascended into heaven
And sitteth on the right hand of the Father
Whence he cometh to judge the living and the dead.
And in the Holy Spirit
The holy church
The remission of sins
The resurrection of the flesh
The life everlasting.
Modern Version as recited today
WE BELIEVE in God the Father Almighty, Maker of heaven and earth: And in Jesus Christ his only Son, our Lord; who was conceived by the Holy Ghost, born of the virgin Mary, suffered under Pontius Pilate, was crucified, dead, and buried; he descended into hell; the third day he rose again from the dead; he ascended into heaven, and sitteth on the right hand of God the Father Almighty; from thence he shall come to judge the quick and the dead. I believe in the Holy Ghost; the holy catholic church; the communion of saints; the forgiveness of sins; the resurrection of the body; and the life everlasting. Amen.
