The earliest known mention of the expression "Apostles' Creed" occurs in a letter of AD 390 from a synod in Milan. The most traditional version of the creed is as follows:
I believe in God, the Father almighty,
creator of heaven and earth.
I believe in Jesus Christ, his only Son, our Lord,
who was conceived by the Holy Spirit
and born of the virgin Mary.
He suffered under Pontius Pilate,
was crucified, died, and was buried;
he descended to hell.
The third day he rose again from the dead.
He ascended to heaven
and is seated at the right hand of God the Father almighty.
From there he will come 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.
*that is, the true Christian church of all times and all places
The Old Roman Symbol (Latin: vetus symbolum romanum), or Old Roman Creed, is an earlier and shorter version of the Apostles’ Creed. It was based on the 2nd-century Rule of Faith and the interrogatory declaration of faith for those receiving Baptism. It is said that this earlier and first adopted version was based on the Trinitarian formula found in The Great Commission in Matthew 28:19. It was widely accepted in the 4th century, that, under the inspiration of the Holy Spirit, each of the Twelve Apostles contributed an article to the twelve articles of this creed:
I believe in God the Father almighty;
and in Christ Jesus His only Son, our Lord,
Who was born of the Holy Spirit and the Virgin Mary,
Who under Pontius Pilate was crucified and buried,
on the third day rose again from the dead,
ascended to heaven,
sits at the right hand of the Father,
whence He will come 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)
The Apostles' Creed (100 A.D.) is the oldest and shortest creed with only 109 words in the traditional version. Only the New Testament creed, "Jesus is Lord," is older. It is also the most often used -- practically every Sunday, except for festivals and seasons when the Nicene Creed is confessed. Undoubtedly, it is the most universal statement of the Christian faith.
By 100 A.D. the Apostles' Creed became the basic statement of faith for the church. In the first century, it was the rule of faith for baptismal candidates. In 390 it became known as the Apostles' Creed, even though it was not written by the apostles but contained the beliefs of the apostles. An ancient legend has it that after Pentecost the apostles agreed on a summary of what they were going to preach. The summary was the Apostles' Creed. Yet, the creed did not reach its final form until the sixth or seventh century. Martin Luther held this creed in such high regard that he used it in his Small Catechism to teach families what a Christian believes. To this day the Small Catechism is used as the basis for youth and adult preparation for church membership in Lutheran churches.
