Christ reveals the mystery to those who think rightly
Cyril is closing his argument, stating that Christ will reveal the knowledge of his own mystery to those who have chosen to think rightly about him.
Divinely, consubstantial, and also to us the same humanly. To those who think thus Christ will reveal the knowledge of his own mystery. For the humanity in Christ was being honored and sanctified. For as far as his own being is concerned, he would not have needed baptism, nor indeed to share in the Holy Spirit. Most of all it will suffice for full assurance that he himself is the giver of the Spirit.
Greek
θεϊκῶς, ὁμοούσιον δὲ καὶ ἡμῖν τὸν αὐτὸν ἀνθρωπίνως. τοῖς οὕτω φρονεῖν ᾑρημένοις ἀναστρέψει Χριστὸς τοῦ καθ' ἑαυτὸν μυστηρίου τὴν γνῶσιν. βʹ. Ἦν γὰρ ἡ ἀνθρώπου φύσις ἡ ἐν Χριστῷ τιμωμένη τε καὶ ἁγιαζομένη· ὅτι γὰρ τό γε ἧκον εἰς τὸ εἶναι, οὔτ' ἂν ἐδεήθη βαπτίσματος, οὔτε μὴν τοῦ Ἁγίου Πνεύματος μετασχεῖν, μάλιστα μὲν ἀρκέσει πρὸς πληροφορίαν τὸ αὐτὸν εἶναι τοῦ Πνεύματος χορηγόν.
