A Warning About Scripture Study

Ἐπιστημονικῶς τὴν θείαν Γραφὴν ἀνελίσσειν ὀφείλεις, καὶ τὰς αὐτῆς δυνάμεις νουμεχῶς ἀνιχεύειν, καὶ μὴ κατατολμᾷν ἁπλῶς τῶν ἀψαύστων καὶ άνεφίκτων μυστηρίων, ἀναξίαις ταῦτα χερσὶν ἐπιτρέπων. Οὕτω γάρ ὁ τολμηρότατος Ὀζίας ἀναθαῥρήσας ἐπιβαλεῖν τοῖς ἀνεγχειρητοις, λέπραν τῷ θράσει προσαπηνέγκατο, καὶ ἄκων ἀποῥῥιφεὶς τῶν ἀνακτόρων, καθότι καὶ νόμος τοῖς λέπρᾳ κατεστιγμένοις τὴν εἴσω τούτων ἀπέκλειεν εἴσοδον. Ἐγράφη δὲ ταῦτα πρὸς νουθεσίαν ἡμῶν, ἵνα καὶ τὰς τόλμας φύγωμεν, καὶ τὰς κολάσεις μὴ πάθωμεν.   Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλιον Πρῶτον Ἐπιστολὴ ΚΔ'  Κρισμῳ Source: Migne PG 78.197a

As one wise you should unroll the Divine Scriptures and investigate them insofar as you are able to do so, for one should not venture in any way to allow an unworthy hand to touch inaccessible and forbidden mysteries. King Uzziah overreached and would have uncleanly touched that which was prohibited, and for his daring he received leprosy, a shaft ripping off his royalty, and thus the law by the marks of leprosy shut him off from access. Let that which is written be a warning to us, that we avoid recklessness and that we do not suffer punishment. Saint Isidore of Pelusium, Book 1, Letter 24 to Crispus
