(Profession of Faith) (381 A.D.)
[English, New Roman Missal Translation]

I believe in one God, the Father almighty, maker of heaven and earth, of all things visible and invisible. I believe in one Lord Jesus Christ, the Only Begotten Son of God, born of the Father before all ages. God from God, Light from Light, true God from true God, begotten, not made, consubstantial with the Father; Through him all things were made. For us men and for our salvation he came down from heaven, and by the Holy Spirit was incarnate of the Virgin Mary, and became man. For our sake he was crucified under Pontius Pilate, he suffered death and was buried, and rose again on the third day in accordance with the Scriptures. He ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead and his kingdom will have no end. I believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son, who with the Father and the Son is adored and glorified, who has spoken through the prophets. I believe in one, holy, catholic, and apostolic Church. I confess one baptism for the forgiveness of sins and I look forward to the resurrection of the dead and the life of the world to come. Amen.

(Credo) [Latin]

Credo in unum Deum, Patrem omnipoténtem, Factórem cæli et terræ, Visibílium ómnium et invisibílium. Et in unum Dóminum Iesum Christum, Fílium Dei Unigénitum, Et ex Patre natum ante ómnia sæcula. Deum de Deo, lumen de lúmine, Deum verum de Deo vero, Génitum, non factum, consubstantiálem Patri: Per quem ómnia facta sunt. Qui propter nos hómines et propter nostram salútem Descéndit de cælis. Et incarnátus est de Spíritu Sancto Ex María Vírgine, et homo factus est. Crucifíxus étiam pro nobis sub Póntio Piláto; Passus, et sepúltus est, Et resurréxit tértia die, secúndum Scriptúras, Et ascéndit in cælum, sedet ad déxteram Patris. Et íterum ventúrus est cum glória, Iudicáre vivos et mórtuos, Cuius regni non erit finis. Et in Spíritum Sanctum, Dóminum et vivificántem: Qui ex Patre [* Filióque] procédit. Qui cum Patre et Fílio simul adorátur et conglorificátur: Qui locútus est per prophétas. Et unam, sanctam, cathólicam et apostólicam Ecclésiam. Confíteor unum baptísma in remissiónem peccatorum. Et expecto resurrectionem mortuorum, Et vitam ventúri sæculi. Amen.

We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible; And in one Lord Jesus Christ, the Son of God, the Only-begotten, Begotten of the Father before all ages, Light of Light, Very God of Very God, Begotten, not made; of one essence with the Father, by whom all things were made: Who for us men and for our salvation came down from heaven, and was incarnate of the Holy Spirit and the Virgin Mary, and was made man; And was crucified also for us under Pontius Pilate, and suffered and was buried; And the third day He rose again, according to the Scriptures; And ascended into heaven, and sits at the right hand of the Father; And He shall come again with glory to judge the living and the dead, Whose kingdom shall have no end. And we believe in the Holy Spirit, the Lord, and Giver of Life, Who proceeds from the Father, Who with the Father and the Son together is worshipped and glorified, Who spoke by the Prophets; And we believe in one, holy, catholic, and apostolic Church. We acknowledge one Baptism for the remission of sins. We look for the Resurrection of the dead, And the Life of the age to come. Amen.
