Perfect and Partial Knowledge

Ποῦ τοίνυν εἰσὶν οἱ τὸ πᾶν ἀπειληφέναι τῆς γνώσεως λέγοντες, οἱ πρὸς τὸ βάραθον τῆς ἀγνωσίας καταπεσόντες; Οἱ γὰρ κατὰ τὸ παρὸν λέγοντες ἀπειληφέναι τὸ πᾶν, εἰς τὸ μέλλον ἐρήμους ἑαυτοὺς τῆς παντελοῦς καθιστῶσι γνώσεως. Ἐγω μὲν γὰρ ὁ λέγων, ὅτι ἐκ μέρους γινώσκω, κἂν εἴπω, ὅτι καταργεῖται ἡ γνῶσις αὕτη, πρὸς τὸ βέλτιον καὶ τελειότερον ὁδεύω, καταργηθείσης τῆς μερικῆς καὶ γενομένης τελειοτέρας. Ἅγιος Ἰωάννης ὁ Χρυσόστομος Περὶ Ἀκαταληπτου, Λόγος Πρῶτος Source: Migne PG 48.704

How then do they say that they have attained to complete knowledge, they who have fallen into the deepest ignorance? For they who say that they have achieved all knowledge now are depriving themselves of perfect knowledge in the future. For if I say I know a part 1 then I am saying that I am advancing to what is better and more perfect, partial knowledge passing away and becoming perfect knowledge. Saint John Chrysostom, On The Incomprehensible Nature Of God, from the First Homily 1 Cor 13.12
