"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 buried; He descended to hell. On the third day He rose again from the dead; He ascended to heaven, and is seated at the right hand of God the Father, From there He will come to judge the living and the dead. I believe in the Holy Spirit the one true Church the communion of the saints, the forgiveness of sins, the Resurrection of the body and the life everlasting.  Amen"
