The Apostles' Creed

I believe in God, the Father almighty, Creator of Heaven and earth, and in Jesus Christ, His only Son, our Lord. He was conceived by the Holy Ghost, and born of the Virgin Mary. He suffered under Pontius Pilate, was crucified, died and was buried. He descended into Hell. On the third day He rose again from the dead. He ascended into Heaven, and is seated at the right hand of God the Father Almighty. He will come again to judge the living 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.

Note:
The Apostles' Creed is said during Baptisms, during the Rosary (optionally), at the Divine Office, etc.

Regarding the line, "He descended into Hell": "Hell" refers to "Sheol" (Hebrew) or "Hades" (Greek) -- the only "realm of the dead" before Heaven was opened. Sheol consists of different areas, or levels:

• Infernus: the place of torment for the unrighteous damned and the demons. This is the place one most often thinks of when one hears the word "Hell.";

• Purgatory: where the saved souls go to be purged of the temporal effects of their sins;

• the Limbo of the Infants (Limbus Infantium): a possible place of perfect, natural subjective happiness to which those who died before Baptism (and so are denied the Beatific Vision) but who have not committed personal sins (so don't warrant punishment) might go;

• the Limbo of the Patriarchs (Limbus Patrum): where the righteous who lived before Jesus came to earth went. It is this part of "Hell" that Christ descended into. It no longer exists.
