Nicene-Constantinopolitan Creed

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 only-begotten Son of God, begotten of the Father before all worlds; God of God, Light of Light, very God of very God; begotten, not made, being of one substance with the Father, by whom all things were made. Who, for us men for our salvation, came down from heaven, and was incarnate by the Holy Spirit of the virgin Mary, and was made man; and was crucified also for us under Pontius Pilate; He suffered and was buried; and the third day He rose again, according to the Scriptures; and ascended into heaven, and sits on the right hand of the Father; and He shall come again, with glory, to judge the quick 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 and the Son;1 who with the Father and the Son together is worshipped and glorified; who spoke by the prophets; and one holy catholic and apostolic Church. We acknowledge one baptism for the remission of sins; and I look for the resurrection of the dead, and the life of the world to come. Amen.

NOTES

1. The Latin text of the Nicene-Constantinopolitan (381) as revised by the Third Council of Toledo (589) ratified the use of the filioque clause  (and the Son) to further define the procession of the Holy Spirit. This revision is received by the Reformed and Presbyterian churches but is not received by the Eastern Churches. Here is a more detailed explanation.

The Received Greek Text

Πιστεύομεν εἰς ἕνα ΘΕΟΝ ΠΑΤΕΡΑ παντοκράτορα, ποιητὴν οὐρανοῦ καὶ γῆς, ὁρατῶν τε πάντων καὶ ἀοράτων.

Καὶ εἰς ἕνα κύριον ἸΗΣΟΥΝ ΧΡΙΣΤΟΝ, τὸν υἱὸν τοῦ θεοῦ τὸν μονογενῆ, τὸν ἐκ τοῦ πατρὸς γεννηθέντα πρὸ πάντων τῶν αἰώνων, φῶς ἐκ φωτός, θεὸν ἀληθινὸν ἐκ θεοῦ ἀληθινοῦ, γεννηθέντα, οὐ ποιηθέντα, ὁμοούσιον τῷ πατρί· διʼ οὔ τὰ πάντα ἐγένετο· τὸν διʼ ἡμᾶς τοὺς ἀνθρώπους καὶ διὰ τὴν ἡμετέραν σωτηρίαν κατελθόντα ἐκ τῶν οὐρανῶν καὶ σαρκωθέντα ἐκ πνεύματος ἁγίου καὶ Μαρίας τῆς παρθένου καὶ ἐνανθρωπήσαντα, σταυρωθέντα τε ὑπὲρ ἡμῶν ἐπὶ Ποντίου Πιλάτου, καὶ παθόντα καὶ ταφέντα, καὶ ἀναστάντα τῇ τρίτῃ ἡμέρᾳ κατὰ τὰς γραφάς, καὶ ἀνελθόντα εἰς τοὺς οὐρανούς, καὶ καθεζόμενον ἐκ δεξιῶν τοῦ πατρός, καὶ πάλιν ἐρχόμενον μετὰ δόξης κρῖναι ζῶντας καὶ νεκρούς· οὗ τῆς βασιλείας οὐκ ἔσται τέλος.

Καὶ εἰς τὸ ΠΝΕΥΜΑ ΤΟ ἌΓΙΟΝ, τὸ κύριον, (καὶ) τὸ ζωοποιόν, τὸ ἐκ τοῦ πατρὸς ἐκπορευόμενον, τὸ σὺν πατρὶ καὶ ὑιῷ συν προσκυνούμενον καὶ συνδοξαζόμενον, τὸ λαλῆσαν διὰ τῶν προφητῶν· εἰς μίαν, ἁγίαν, καθολικὴν καὶ ἀποστολικὴν ἐκκλησίαν· ὁμολογοῦμεν ἓν βάπτισμα εἰς ἄφεσιν ἁμαρτιῶν· προσδοκῶμεν ἀνάστασιν νεκρῶν, καὶ ζωὴν τοῦ μέλλοντος αἰώνος. Ἀμήν.

Received Latin Text

Credo in unum DEUM PATREM omnipotentem; factorem cœli et terrœ, visibilium omnium et invisibilium.

Et in unum Dominum JESUM CHRISTUM, Filium Dei unigenitum, et ex Patre natum ante omnia sæcula [Deum de Deo], Lumen de Lumine, Deum verum de Deo vero, genitum, non factum, consubstantialem Patri; per quem omnia facta sunt; qui propter nos homines et propter nostram salutem descendit de cœlis, et incarnatus est de Spiritu Sancto ex Maria virgine, et homo factus est; crucifixus etiam pro nobis sub Pontio Pilato, passus et sepultus est; et resurrexit tertia die, secundum Scripturus; et ascendit in cœlum, sedet ad dexteram Patris; et iterum venturus est, cum gloria, judicare vivos et mortuos; cujus regni non erit finis.

Et in SPIRITUM SANCTUM, Dominum et vivificantem, qui ex Patre [Filioque] procedit; qui cum Patre et Filio simul adoratur et conglorificatur; qui locutus est per Prophetas. Et unam, sanctam, catholicam et apostolicam ecclesiam. Confiteor unum baptisma in remissionem peccatorum; et expecto resurrectionem mortuorum, et vitam venturi seculi. Amen.
