The Nicene Creed

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.

I affirm the Nicene Creed.

Greek Version
Πιστεύω εἰς ἕνα Θεόν, Πατέρα, Παντοκράτορα, ποιητὴν οὐρανοῦ καὶ γῆς, ὁρατῶν τε πάντων καὶ ἀοράτων.
Καὶ εἰς ἕνα Κύριον Ἰησοῦν Χριστόν, 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 Γραφάς.
Καὶ ἀνελθόντα εἰς τοὺς οὐρανοὺς καὶ καθεζόμενον ἐκ δεξιῶν τοῦ Πατρός.
Καὶ πάλιν ἐρχόμενον μετὰ δόξης κρῖναι ζῶντας καὶ νεκρούς, οὗ τῆς βασιλείας οὐκ ἔσται τέλος.
Καὶ εἰς τὸ Πνεῦμα τὸ Ἅγιον, τὸ κύριον, τὸ ζῳοποιόν,
τὸ ἐκ τοῦ Πατρὸς ἐκπορευόμενον,
τὸ σὺν Πατρὶ καὶ Υἱῷ συμπροσκυνούμενον καὶ συνδοξαζόμενον,
τὸ λαλῆσαν διὰ τῶν προφητῶν.
Εἰς μίαν, Ἁγίαν, Καθολικὴν καὶ Ἀποστολικὴν Ἐκκλησίαν.
Ὁμολογῶ ἓν βάπτισμα εἰς ἄφεσιν ἁμαρτιῶν.
Προσδοκῶ ἀνάστασιν νεκρῶν.
Καὶ ζωὴν τοῦ μέλλοντος αἰῶνος.
Ἀμήν
