( To the Reader 63 It is doubtful whether this caution proceeded from Cyril himself when issuing a written copy of his Lectures, or from some later editor. Eusebius (E.H. v. 20) has preserved an adjuration by Irenæus at the end of his treatise, On the Ogdoad: I adjure thee, who mayest transcribe this book, by Our Lord Jesus Christ, and by His glorious advent, when He cometh to judge the quick and the dead, to compare what thou hast written and correct it carefully by this copy, from which thou hast transcribed it; this adjuration also thou shalt write in like manner, and set it in the copy. .)
These Catechetical Lectures for those who are to be enlightened thou mayest lend to candidates for Baptism, and to believers who are already baptized, to read, but give not at all 64 Gr. τὸ σύνολον. Plat. Leg. 654 B; Soph. 220 B. , neither to Catechumens, nor to any others who are not Christians, as thou shalt answer to the Lord. And if thou make a copy, write this in the beginning, as in the sight of the Lord.
[Τὰς τῶν Φωτιζομένων κατηχήσεις ταύτας, τοῖς μὲν τῷ βαπτίσματι προσερχομένοις, καὶ τοῖς τὸ λουτρὸν ἔχουσιν ἤδη πιστοῖς, εἰς ἀνάγνωσιν παρεχόμενος, μὴ δὸς τὸ σύνολον μήτε κατηχουμένοις, μήτε ἄλλοις τισὶ τοῖς μὴ οὖσι χριστιανοῖς: ἐπεὶ τῷ Κυρίῳ λόγον δώσεις. Καὶ ἐὰν ποιῇς ἀντίγραφον, ὡς ἐπὶ Κυρίου ταῦτα πρόγραψον].
