Adding And Taking Away

Οὐ προσθήσεις ἐπ' αὐτὸ. οὐδὲ ἀφελεῖς ἀπ' αὐτοῦ Οἱ ἄνθρωποι ἁμαρτάνοντες γενικῷ λόγῳ διχῶς ἁμαρτάνουσιν, ἢ ὑπερβαίνοντες τὰς ἐντολὰς ἢ ὑποκενοῦντες. Ὅταν γὰρ μὴ ἀπὸ ἐπιστήμης πολιτευόμεθα, μηδὲ γινώσκοντες τὰ μέτρα τῆς δικαιοσύνης σφαλλόμεθα, καὶ ἔσθ' ὅτε ὑπερβαίνοντες τὸν κανόνα, φαντασίᾳ τοῦ ποιεῖν τι κρεῖττον, ἐκπίπτομεν τοῦ προκειμένου. Ὠριγένης, Εἰς Δευτερονόμιον, Κεφ Κ', Ἐκλογή Source: Migne PG 12.812a

You shall not add to it, nor take anything away. 1 Men who sin generally do so for two causes, either going beyond the commandments, or by being rid of them. For when we live apart from knowlege, not knowing the standards of righteousness, we are deceived, and when we go beyond the commandments, we act in the delusion that we do better, falling away from what has been set before us. Origen, On Deuteronomy, Fragment 1 Deut 12.32
