The formulas of faith are important because they permit one to express, assimilate, celebrate, and share together with others the truths of the faith through a common language.
The Church, although made up of persons who have diverse languages, cultures, and rites, nonetheless professes with a united voice the one faith that was received from the one Lord and that was passed on by the one Apostolic Tradition. She confesses one God alone, Father, Son, and Holy Spirit, and points to one way of salvation. Therefore we believe with one heart and one soul all that is contained in the Word of God, handed down or written, and which is proposed by the Church as divinely revealed.
The Apostles’ Creed
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; 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 thence 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.
