15:1
Ὁ δ ὡς ἑαυτὸν ἑώρα μὴ ἐπαρκοῦντα τῇ τῶν θείων βαθυτέρᾳ σχολῇ, τῇ τε ἐξετάσει καὶ ἑρμηνείαι τῶν ἱερῶν γραμμάτων, καὶ προσέτι τῇ τῶν προσιόντων κατηχήσει, μηδ ἀναπνεῦσαι συγχωρούντων αὐτῷ, ἑτέρων ἐφ ἑτέροις ἐξ ἕω καὶ μέχρις ἐσπέρας ἐπὶ τὸ παρ αὐτῷ διδασκαλεῖον φοιτώντων, διανείμας τὰ πλήθη, τὸν Ἡρακλᾶν τῶν γνωρίμων προκρίνας, ἔν τε τοῖς θείοις σπουδαῖον καὶ ἄλλως ὄντα λογιώτατον ἄνδρα καὶ φιλοσοφίας οὐκ ἄμοιρον, κοινωνὸν καθίστη τῆς κατηχήσεως, τῷ μὲν τὴν πρώτην τῶν ἄρτι στοιχειουμενων εἰσαγωγὴν ἐπιτρέψας, αὐτῷ δὲ τὴν τῶν ἐν ἕξει φυλάξας ἀκρόασιν.
But when he saw that he was not sufficient for the deeper study of the divine things, and for the examination and interpretation of the sacred writings, and besides for the catechizing of those who came to him—they not allowing him even to draw breath, one after another from morning until evening frequenting his school—he divided the multitudes, and choosing out Heraclas from among his acquaintances, a man earnest in the divine things and otherwise most learned and not without a share of philosophy, he established him as a partner in the catechizing, entrusting to him the first introduction of those just being instructed in the elements, while reserving for himself the hearing of those already advanced.
但他見自己不足以兼顧神聖之事更深的研究、聖經的考查與詮釋，加上對前來之人的慕道教導——這些人甚至不容他喘息，從早到晚一個接一個地往來於他的學校——他便把眾人分開，從相識之人中揀選了黑拉克拉斯，這人在神聖之事上殷勤，在其他方面也極其博學，並非沒有哲學的素養，便立他作慕道教導的同工，將那些剛開始受啟蒙的初學者的入門課託付給他，而為自己保留那些已有根柢之人的講授。
