12. When, therefore, the Lecture is delivered, if a Catechumen ask thee what the teachers have said, tell nothing to him that is without  44  On the Disciplina Arcani, or rule against publishing the Christian Creed and Mysteries to Catechumens and Gentiles, see Index, “Mysteries.” . For we deliver to thee a mystery, and a hope of the life to come. Guard the mystery for Him who gives the reward. Let none ever say to thee, What harm to thee, if I also know it? So too the sick ask for wine; but if it be given at a wrong time it causes delirium, and two evils arise; the sick man dies, and the physician is blamed. Thus is it also with the Catechumen, if he hear anything from the believer: both the Catechumen becomes delirious (for he understands not what he has heard, and finds fault with the thing, and scoffs at what is said), and the believer is condemned as a traitor. But thou art now standing on the border: take heed, pray, to tell nothing out; not that the things spoken are not worthy to be told, but because his ear is unworthy to receive. Thou wast once thyself a Catechumen, and I described not what lay before thee. When by experience thou hast learned how high are the matters of our teaching, then thou wilt know that the Catechumens are not worthy to hear them.

Ὅτε τοίνυν ἡ κατήχησις λέγηται, ἐάν σε κατηχούμενος ἐξετάσῃ, τί εἰρήκασιν οἱ διδάσκοντες, μηδὲν λέγε τῷ ἔξω: μυστήριον γάρ σοι παραδίδομεν, καὶ ἐλπίδα μέλλοντος αἰῶνος: τήρησον τὸ μυστήριον τῷ μισθαποδότῃ. Μή ποτέ σοί τις εἴπῃ: τί βλάπτῃ, ἐὰν κἀγὼ μάθω; Καὶ οἱ νοσοῦντες τὸν οἶνον ζητοῦσιν: ἀλλ' ἐὰν ἀκαίρως δοθῇ, φρενῖτιν ἐργάζεται: καὶ δύο κακὰ γίνεται, καὶ ὁ νοσῶν ἀπόλλυται, καὶ ὁ ἰατρὸς διαβάλλεται: οὕτως ὁ κατηχούμενος, ἐὰν ἀκούσῃ παρὰ πιστοῦ: καὶ ὁ κατηχούμενος φρενιτιᾷ, οὐκ οἶδε γὰρ τί ἤκουσε, καὶ ἐλέγχει τὸ πρᾶγμα, καὶ ἐκμυκτηρίζει τὸ λεγόμενον: καὶ ὁ πιστὸς ὡς προδότης κατακρίνεται. Ἤδη δὲ σὺ ἐν μεθορίῳ στήκεις, βλέπε μοι μὴ ἐκλαλήσῃς: οὐχ ὅτι οὐκ ἄξια λαλιᾶς τὰ λεγόμενα, ἀλλ' ὅτι ἡ ἀκοὴ ἀναξία τοῦ δέξασθαι: ἦς καὶ σύ ποτε κατηχούμενος, οὐ διηγησάμην σοι τὰ προκείμενα: ὅταν τῇ πείρᾳ λάβῃς τὸ ὕψωμα τῶν διδασκομένων, τότε ἂν γνώσῃ, ὅτι ἀνάξιοι οἱ κατηχούμενοι τῆς ἀκοῆς.
