Concerning catechumens who have lapsed, it has seemed good to the holy and great synod that, after being hearers only for three years, they then pray with the catechumens.
Περὶ τῶν κατηχουμένων, καὶ παραπεσόντων, ἔδοξε τῇ ἁγίᾳ καὶ μεγάλῃ συνόδῳ, ὥστε, τριῶν ἐτῶν αὐτοὺς ἀκροωμένους μόνον, μετὰ ταῦτα εὔχεσθαι μετὰ τῶν κατηχουμένων.
