The Hidden Hook

Ὥσπωερ οἱ ναυτικοὶ βρώματι τὸ δέλεαρ κατακρύπτουσι, καὶ τοὺς ἰχθύας ἀπροόπτως ἀγρεύουσιν· οὕτως οἱ πονηροὶ τῶν αἱρέσεων σύμμαχοι, τῇ χρηστολογίᾳ τὰς ἑαυτῶν κακονοίας καλύπτοντες, ἀγκιστρεύουσι τοὺς ἁπλουστέρους πρὸς θάνατον. Πάσῃ τοίνυν φυλακῇ τήρει τὴν σὴν καρδίαν, μή που δόκησιν τὴν τοῦ Χριστοῦ φύσιν μετὰ τὴν σάρκωσιν δέξῃ. Θατέρας γάρ ἐστιν ἀναίρεσις ἡ περὶ μιᾶς τούτων συγκατάθεσις· ἤ τῆς θείας τραπείσης, ἤ τῆς ἡμῶν μειωθείσης. Αὕτη τοῦ Μάνητος ἡ Χάρυβδις, δι ἧς πάντας εἰς γέενναν καταγαγεῖν ἐσπούδασε. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλίον Πρῶτον, Ἐπιστολὴ ΡΒ’ Τιμοθεῳ Αναγνωστῃ Source: Migne PG 78.252c

As fishermen hide the hook in food and catch the fish unawares, so it is with the wicked defenders of heresies, for hiding their evils under golden words they hook simple folk and draw them to death. Therefore with every care guard your heart, lest you ever come to accept that the nature of Christ after the incarnation was a mere phantom. In another way there is ruin by agreement to one nature alone, either removing the Divine nature or eliminating our own. This is the Charybdis of Mani through which he strove to drive everyone to down hell. Saint Isidore of Pelusium, Book 1, Letter 102, to Timotheus the Lector
