This creed is similar to the Apostles’ and Nicene Creeds. It is found in the Antiphonary of Bangor, a book of canticles, responses and prayers, written in Ireland around A.D. 680.
I believe in God the Father almighty, invisible, creator of all things visible and invisible.
I believe also in the Lord Jesus Christ, his only Son, our Lord, God almighty, conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified and buried and descended into hell, the third day he rose from the dead. He ascended into heaven, and is seated at the right hand of God the Father almighty. From there he will come to judge the living and the dead.
I believe also in the Holy Spirit, God almighty, of one substance with the Father and the Son. I believe in the holy catholic church, the forgiveness of sins, the communion of saints, and the resurrection of the body.
I believe in life after death, and eternal life in the glory of Christ. All this I believe in God. Amen.

Original in Latin:
Credo in Deum Patrem omnipotentem, invisibilem, omnium creaturarum visibilium et invisibilium conditorem.
Credo et in Jesum Christum, Filium ejus unicum, Dominum nostrum, Deum omnipotentem, conceptum de Spiritu Sancto, natum de Maria Virgine, passum sub Pontio Pilato, qui crucifixus et sepultus descendit ad inferos, tertia die resurrexit a mortuis, ascendit in coelis, seditque ad dexteram Dei Patris omnipotentis, exinde venturus judicara vivos ac mortuos.
Credo et in Spiritum Sanctum, Deum omnipotentem, unam habentem substantiam cum Patre et Filio. Sanctam esse ecclesiam catholicam, abremissam peccatorum, sanctorum communionem, carnis resurrectionem.
Credo vitam post mortem, et vitam aeternam in gloria Christi. Haec omnia credo in Deum. Amen.
