He that is of God hears God's words: you therefore hear them not, because you are not of God.
Read Chapter 8
Cyril of Alexandria
AD 444
We must here understand that certain are of God, not as though begotten of His Essence (for that were foolish), nor yet according to what is said through Paul, All things are of God (for since He is Creator and Maker of all things who giveth being to all, the Divine Paul saith that all things are of Him): but it will not harmonize so to understand it here, for all are of God, both bad and good, in so far as He is Creator of all. He says therefore that he is of God who by virtue and a right conversation is related to God, and accounted worthy of kinness to Him, in that He deigns to enrol such among His children. He therefore, He says, that is of God will receive most readily and gladly the Divine words (for that which is of kin and own is always dear) but he that is not of God, i. e., he who in no wise prizes relationship with Him, will not most gladly hear the Divine words: for neither will good easily inexist the bad, nor will longing for virtue be to them a thing worth fighting for, since their mind has been filled with the extremest depravity and looks to only its own will.
But when Christ says, He that is of God heareth God's words, let no one think that He is bidding us to give the Divine voice entry in merely our bodily ears. For who that is, even though he be a thoroughly bad man, will not surely hear the voice of him who speaketh, if he have not by some disease lost his hearing? But the word heareth, He here puts instead of Consents, believes and lays up in his mind, as it is said in the book of Proverbs, The wise will receive commandments in his heart. For that of the unwise or despisers the word borne about, like some meaningless sound and like some din that annoys to no purpose, forthwith departs from the recipients: but into the heart of the prudent like some generous soil it sinks in.
Full wisely does now the Lord, convicting the madness of the Jews and shewing that they blaspheme without restraint, say that His words are the words of God. For He reinstructs them (He says) to think more becomingly of Him and not to deem that of Joseph or any other of those on the earth did He of a truth spring, but to believe that of the Essence of God the Father He hath appeared God of God. Which they indeed understanding are annoyed and burn with hotter wrath, adding iniquity to their iniquity, as it is written, through those things whereby they insult Him yet more.
