The Finger And The Spirit

Ὅτι μὲν ἔφης, κατὰ τοῦ ἁγίου Πνεύματος ἡ βλασφήμια, δῆλον ἐξ αὐτῆς τῆς τοῦ Κυρίου φωνῆς λεγούσης, Ὅς ἂν εἴποι κατὰ τοῦ Πνεύματος τοῦ ἁγίου, οὐκ ἀφεθήσεται αὐτῷ. Καὶ ὅτι ἡ κατὰ τοῦ Πνεύματος τοῦ ἀγίου ἐκδικεῖται ἡ βλασφημία σαφές. Ὅτι δὲ τῆς θείας ἐστὶ τὸ Πνεῦμα τὸ ἅγιον οὐσίας, τοῦτο σὺ ᾔτηας Γραφικῶς τρανωθῆναι. Ἔξεστί σοι ἀγχινοῦντι καὶ μικρὸν προελθόντι ἐκ τῶν ἐν χερσὶ τοῦ Κυρίου φωνῶν καὶ τὴν λύσιν εὑρεῖν. Εἰ ἐγὼ, φησὶν, ἐν τῷ βεελζεβοὺλ ἐκβάλλω τὰ δαιμόνια, οἱ  υἱοὶ ὑμῶν ἐν τίνι ἐκβάλλουσιν; Εἰ δὲ πνεύματι Θεοῦ ἐκβάλλω ταῦτα, ἄρα ἔφθασεν ἐφ' ὑμᾶς ἡ βσαιλεία τοῦ Θεοῦ. Ἔν τῷ ἑτέρῳ σαφέστερον εἰρηκὼς εὐαγγελιστὴς, Εἰ δὲ ἐγὼ ἐν δακτύλῳ Θεοῦ ἐκβάλλω τὰ δαιμόνια. Δάκτυλον Θεοῦ, τὸ Πνεῦμα λέγων τὸ ἅγιον. Δάκτυλος δὲ, ὡς ἐν ὑποδείγματι τῷ καθ' ἡμᾶς, τῆς οὐσὶας ἐστὶ τοῦ σώματος. Τὴν τοίνυν ἀχώρισιον καὶ συγγενῆ τῆς θείας οὐσίας τοῦ Πνεύματος τοῦ ἁγίου ὑπόστασιν, τῷ τοῦ δακτύλου ὀνόματι ἐφανέρωσε.

What the blasphemy against the Holy Spirit may be, which you ask, the voice of the Lord makes clear when He says, 'If someone blasphemes against the Holy Spirit, it shall not be forgiven him.' 1 And so know that blasphemy against the Holy Spirit shall be punished. And then you enquire where it is clearly witnessed in Scripture that the Holy Spirit is of the Divine nature. With a little attention and advancement you will find the solution in your hands by the voice of Lord. He says, 'For if I cast out demons by Beelzebub, by whom do your sons cast them out? And if I cast them out by the spirit of God, then undoubtedly the kingdom of heaven has come among you.' 2 And another Evangelist speaks more openly: 'If I cast out demons by the finger of God.' 3 In which passage the finger of God is to be understood as the Holy Spirit. And the finger, which is given us as a figure, is of the essence of the body. So inseparable from and cognate with the Divine essence is the person of the Holy Spirit, which is declared by the word of finger.
