καὶ εἰς ἕνα Κύριον Ἰησοῦν Χριστὸν 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, δι᾽ οὗ τὰ πάντα ἐγένετο· τὸν δι᾽ 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 γραφὰς, καὶ ἀνελθόντα εἰς τοὺς οὐρανοὺς, καὶ καθεζόμενον ἐν δεξιᾷ τοῦ Πατρὸς, καὶ πάλιν ἐρχόμενον μετὰ δόξης κρῖναι ζῶντας καὶ νεκρούς, οὗ τῆς βασιλείας οὐκ ἔσται τέλος·
For reference, below is an English translation of the above Koine Greek text.
We believe in one God, the Father almighty, maker of heaven and earth, of all things visible and invisible;
And [we believe] in one Lord, Jesus Christ, the only begotten Son of God, begotten from the Father before all ages, light from light, true God from true God, begotten not made, of one substance with the Father, through Whom all things came into existence, Who because of us men and because of our salvation came down from the heavens, and was incarnate from the Holy Spirit and the Virgin Mary and became man, and was crucified for us under Pontius Pilate, and suffered and was buried, and rose again on the third day according to the Scriptures and ascended to heaven, and is sitting on the right hand of the Father, and will come again with glory to judge living and dead, of Whose kingdom there will be no end;
And [we believe] in the Holy Spirit, the Lord and life-giver, Who proceeds from the Father, Who with the Father and the Son is together worshipped and together glorified, Who spoke through the prophets;
[We believe in] one holy catholic and apostolic Church. We confess one baptism to the forgiveness of sins. We look forward to the resurrection of the dead and the life of the world to come.
