I believe in God, the Father Almighty, Creator 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, 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; from there He shall 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 life everlasting. Amen.
The Apostles' Creed is so called because it is rightly considered to be a faithful summary of the apostles' faith. It is the ancient baptismal symbol of the Church of Rome. Its great authority arises from this fact: it is the Creed of the Roman Church, the See of Peter, the first of the apostles, to which he brought the common faith.

This Creed is the spiritual seal, our heart's meditation and an ever-present guardian; it is, unquestionably, the treasure of our soul.
