On the admission of Novatians into church communion through confirmation.
That those who convert from heresies, that is, from the Novatians, Photinians and Quaternates, whether they were catechumens or faithful, are not accepted until they anathematize every heresy, especially the one in which they were found. And after this, those who are called faithful by them, having thoroughly studied the Creed and having accepted the anointing of the holy myrrh, partake of the Holy Mysteries.
Greek original
Περὶ τοῦ τοὺς ἐκ τῶν αἱρέσεων, τοὐτέστι Ναυατιανῶν, ἤτοι Φωτεινιανῶν, ἢ Τεσσαρεσκαιδεκατιτῶν, ἐπιστρεφόμενους, εἴτε κατηχουμένους, εἴτε πιστοὺς τοὺς παρ᾽ ἐκείνοις, μὴ προσδέχεσθαι, πρὶν ἀναθεματίσωσι πᾶσαν αἵρεσιν, ἐξαιρέτως δὲ ἐν ᾗ κατείχοντο· καὶ τότε λοιπὸν τοὺς λεγομένους παρ᾽ αὐτοῖς πιστούς, ἐκμαθάνοντας τὰ τῆς πίστεως σύμβολα, χρισθέντας τε τῷ ἁγίῳ χρίσματι, οὕτω κοινωνεῖν τῶν μυστηρίων τῶν ἁγίων.
