If any bishop or presbyter does not baptise, according to the Lord's ordinance, into the Father and Son and Holy Spirit, but into three Unoriginates, or into three Sons, or into three Comforters, let him be deposed.
Εἴ τις ἐπίσκοπος, ἢ πρεσβύτερος, κατὰ τὴν τοῦ Κυρίου διάταξιν μὴ βαπτίσῃ εἰς Πατέρα καὶ Υἱὸν καὶ ἅγιον Πνεῦμα, ἀλλ᾿ εἰς τρεῖς ἀνάρχους, ἢ εἰς τρεῖς υἱούς, ἢ εἰς τρεῖς παρακλήτους, καθαιρείσθω.
