The basic creed of Reformed churches, as most familiarly known, is called the Apostles' Creed. It has received this title because of its great antiquity; it dates from very early times in the Church, a half century or so from the last writings of the New Testament.
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 of the Holy Spirit,
born of the Virgin Mary,
suffered under Pontius Pilate,
was crucified, died, and was buried;
He descended to the dead.* ("into hell")
On the third day He arose again.
He ascended into heaven,
is seated at the right hand of the Father.
and 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.
*The word "catholic" refers not to the Roman Catholic Church, but to the universal church of the Lord Jesus Christ.
