The Apostles’ Creed, though not written by the apostles, is the oldest creed of the Christian church. It is a widely used summary of what Christians believe.
The Apostle's Creed
I 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 Spirit,
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 sits at the right hand of God the Father Almighty;
From there he shall come to judge the living and the dead.
I believe in the Holy Ghost;
The universal Church*,
the Communion of Saints;
The Forgiveness of sins;
The Resurrection of the body,
And the Life everlasting. Amen.
*the original reads "Holy catholic Church", "catholic" at the time meant "universal", as in the collection of believers throughout time and across the world.
