Hippolytus, On Christ and Antichrist
Since you wished to learn the precise details of the topics you proposed to us, my beloved brother Theophilus, I considered it reasonable to set the matters you seek before your eyes, drawing abundantly from the divine Scriptures themselves as from a holy spring. I did this so that you would not only delight in these things by hearing them with your ears, but also, having been instructed by the power of the realities themselves, you might be able to glorify God in every way.
Greek
Ι. Βουληϑέντι σοι zart ἀχρίβειαν ἐχμαϑεῖν τὰ προτεϑέντα ὑπι σοῦ ἡμῖν κεφάλαια, ἀγαπητέ μου ἀδελφὲ Θεόφιλε, εὔλογον ἡγησάμην, ἀφϑόνως ἀρυσάμενος ὡς ἐὲ ἁγίας πηγῆς ἐξ αὐτῶν τῶν ϑείων γραφῶν καταστῆσαί σοι κατ᾽ ὀφϑαλμὸν τὰ ζητούμενα" ἵνα μὴ μόνον ταῖς τῶν ὥτων ἀχοαῖς ἐγκαταϑέμενος ταῦτα εὐφρανϑῆς, ἀλλὰ δυνάμει καὶ αὐτὰ τὰ πράγϊματα ἐνιστορήσας κατὰ πάντα τὸν ϑεὸν δοξάσαι δυνηϑῆς.
