Rule of Faith (Regula Fidei)

46 Custom

The rule of faith is kind of a summary statement. It incorporates a set of doctrines based on Scripture. It was especially used as a unity statement in order to define Christianity (i.e. against gnostics), as a exegetical base, or as a baptismal formula. It can be found in various forms among the Church Fathers (late second century onward). Text presented below is a version from Irenaeus Against Heretics. 

…τὴν εἰς ἕνα Θεὸν Πατέρα παντοκράτορα, τὸν πεποιηκότα τὸν οὐρανὸν, καὶ τὴν γῆν, καὶ τὰς θαλάσσας, καὶ πάντα τὰ ἐν αὐτοῖς, πίστιν· καὶ εἰς ἕνα Χριστὸν Ἰησοῦν, τὸν υἱὸν τοῦ Θεοῦ, τὸν σαρκωθέντα ὑπὲρ τῆς ἡμετέρας σωτηρίας· καὶ εἰς Πνεῦμα ἅγιον, τὸ διὰ τῶν προφητῶν κεκηρυχὸς τὰς οἰκονομίας, καὶ τὰς ἐλεύσεις, καὶ τὴν ἐκ Παρθένου γέννησιν, καὶ τὸ πάθος, καὶ τὴν ἔγερσιν ἐκ νεκρῶν, καὶ τὴν ἔνσαρκον εἰς τοὺς οὐρανοὺς ἀνάληψιν τοῦ ἠγαπημένου Χριστοῦ Ἰησοῦ τοῦ Κυρίου ἡμῶν, καὶ τὴν ἐκ τῶν οὐρανῶν ἐν τῇ δόξῃ τοῦ Πατρὸς παρουσίαν αὐτοῦ ἐπὶ τὸ ἀνακεφαλαιώσασθαι τὰ πάντα, καὶ ἀναστῆσαι πᾶσαν σάρκα πάσης ἀνθρωπότητος…

…in one God, the Father Almighty, who made the heaven and the earth and the seas and all the things that are in them; and in one Christ Jesus, the Son of God, who was made flesh for our salvation; and in the Holy Spirit, who made known through the prophets the plan of salvation, and the coming, and the birth from a virgin, and the passion, and the resurrection from the dead, and the bodily ascension into heaven of the beloved Christ Jesus, our Lord, and his future appearing from heaven in the glory of the Father to sum up all things and to raise anew all flesh of the whole human race…
