Canon 79
A ban on one ritual associated with the Nativity of Christ.
Confessing that the Divine birth from the Virgin was seedless and painless (ἀλόχευτον), and preaching this to the entire flock, we admonish those who, out of ignorance, do something inappropriate. It turned out that after the day of the Holy Nativity of Christ our God, some prepare bread from wheat flour and pass it on to each other under the pretext of supposedly honoring the birth (λοχειῶν) of the All-Immaculate Virgin Mother, therefore we decree that believers should not do anything like that. For to describe and imagine Her indescribable birth according to the example of what is usual and characteristic of us does not mean to give honor to the Virgin, who above mind and word gave birth to the incontainable Word in the flesh. So, if anyone from now on is caught doing something similar, then if he is a cleric, he will be deposed, and if he is a layman, he will be excommunicated.
Greek original
Ἀλόχευτον τὸν ἐκ τῆς Παρθένου θεῖον τόκον ὁμολογοῦντες, ὡς καὶ ἀσπόρως συστάντα, καὶ παντὶ τῷ ποιμνίῳ κηρύσσοντες, τοὺς ἐξ ἀγνοίας πράττοντάς τι τῶν οὐ δεόντων, διορθώσει καθυποβάλλομεν. Ὅθεν, ἐπειδή τινες μετὰ τὴν ἡμέραν τῆς ἁγίας τοῦ Χριστοῦ τοῦ Θεοῦ ἡμῶν γεννήσεως, δείκνυνται σεμίδαλιν ἔψοντες, καὶ ταύτης ἀλλήλοις μεταδιδόντες, προφάσει τιμῆς δῆθεν λοχείων τῆς ἀχράντου Παρθενομήτορος, ὁρίζομεν, μηδὲν τοιοῦτον ὑπὸ τῶν πιστῶν τελεῖσθαι. Οὐ γὰρ τιμή γε τοῦτο τῇ Παρθένῳ, τῇ ὑπὲρ νοῦν καὶ λόγον τὸν ἀχώρητον τεκούσῃ Λόγον σαρκί, ἐκ τῶν κοινῶν τε καὶ καθ᾿ ἡμᾶς τὰ κατὰ τὸν ἀφραστον αὐτῆς τόκον ὁρίζειν καὶ ὑπογράφειν. Εἴ τις οὖν ἀπὸ τοῦ νῦν πράττων τοιοῦτόν τι φωραθείη, εἰ μὲν κληρικὸς εἴη, καθαιρείσθω· εἰ δὲ λαϊκός, ἀφοριζέσθω.
