Jude 1:8

“"Similarly to the same," he says, "also those dreamers,"—that is, who dream in their imagination lusts and wicked desires, regarding as good not that which is truly good, and superior to all good,—"defile the flesh, despise dominion, and speak evil of majesty," that is, the only Lord, who is truly our Lord, Jesus Christ, and alone worthy of praise. They "speak evil of majesty," that is, of the angels.”

“Jude calls them "dreamers" because they have no idea of the truth but fantasize as if they were dreaming and concoct doctrines full of impiety. They say that our flesh, that is to say, our body, is the work of the devil and blaspheme the lordship and glory of the Holy Trinity, accepting the Father as the eternal and uncreated One but reducing the Son and the Holy Spirit to the status of creatures made in time. These are the noxious teachings of Marcion and Arius, which explains why the apostle expresses himself so sharply against them. They do not confess that there is one God, Maker of both the visible and the invisible worlds, but they deify matter and darkness and detest the flesh. Jude condemns these people, even to the point of saying that they have polluted their mind and their entire being.”

“Having set forth the examples just mentioned, the apostle left it to the listener himself to infer the conclusion from them. What conclusion? If God dealt thus with those people, not regarding their former good lot, then will today's impious ones be saved by the fact that the Son of God came into the world for mankind, endured reproach for them, and bore sufferings? No one can say this. For although He is merciful, He is also truly righteous, and in true justice He did not spare those who sinned, while in His mercy He brought harlots and tax collectors into the Kingdom (Matt. 21:31). Such is the conclusion that follows; but the apostle omitted it, and did so either for the reason we stated before, or following the example of holy Peter, when he said: "if God spared not the angels that sinned" (2 Pet. 2:4), and so on. Thus we speak of this. The words "dreamers who defile the flesh" are spoken with remarkable modesty; for by the expression "dreamers" the apostle only hinted at the extremely shameful side of the matter. Let us reveal it in part and insofar as is fitting, borrowing information about this from the work of Saint Epiphanius of Cyprus, which he called the Panarion. He says: these fornicators and defilers, shamefully uniting with women, do not release seed into the womb, but, not completing the defilement, take it into their own hands and immediately place it into the mouths of the women with whom they were debauching themselves, and thus these impure ones withdraw from each other, imagining that they have done something great. It is this unclean handful, on account of the incompleteness of the act, that the apostle calls dreaming, for such defilement occurs during sleep. Defiling their flesh with such vile offering, they also madly rise up against the Divine nature, rejecting Its sovereignty and dominion over all. Saint Irenaeus, Bishop of Lyons, spoke of this more extensively in his work "Exposure of Falsely-Named Knowledge." Otherwise: the apostle testifies to the depravity of the heretics, saying that they are impure in life and utterly vile in knowledge. They, he says, "reject authorities," that is, they reject the performance of the mystery of Christ — they reject it because instead of angelic mysteries they perform their own abominations. "They speak evil of dignities" (δόξας). By "dignities" one should understand the various opinions of wise men, called among the notable Greeks "theses" (θέσεις), by which they mean lofty opinions, accessible not to everyone, but only to those acquainted with philosophy. A witness to what we have said is the Apostle Paul. When the Athenians brought him to the Areopagus and he preached to them the teaching about God, they considered him a babbler (Acts 17). Thus, just as they called the teaching of the apostles babbling, so also they called the aforementioned "dignities." For this reason, speaking of men gifted by God and inspired by God, the Apostle Jude used the word "dignities," as a common and universally known term. Another explanation: by "dignities" he perhaps means the Old and New Testaments. Or: by "dignities" he means ecclesiastical authorities, whom they spoke evil of, as the beloved John indicates in his third epistle (3 John 1:9–10), where he writes that Diotrephes reviles them with wicked words.”

“Likewise, these dreamers defile the flesh, reject authority, and blaspheme glorious beings. Furthermore, what he says: "Likewise, these dreamers defile the flesh," it is worthy of admiration that Jude has expressed the speech so modestly. For he indeed testifies much filthiness and nerve about them, saying that their life is impure, and their tongue is especially lustful: however, he rightly comprehends the fervent immorality of their actions through this word ἐνυπνιαζόμενοι (that is, dreaming or agitated by sleeplessness), which we will briefly and appropriately reveal, taking understanding from the work that blessed Epiphanius, bishop of Cyprus, published about these, which he called the Panarion (26). For he says here that those wicked Borborites (that is, those filled with filth and sludge) when they mixed with foul women, did not dispense semen into the womb, but with an imperfect abomination, they received it with their own hands, and immediately inserted it into the mouths of the women with whom they had been corrupted: and thus they departed from each other impure, thinking they had accomplished something great. This unclean drama is called a dream because such things are also found in dreams. Therefore, by this filthy assumption, they further rage against the divine nature, Jude says, despising its dominion and the authority it has over the universe. Moreover, blessed Irenaeus of Lyons spoke more broadly about these things in his Refutation of the So-called Knowledge, from which anyone who wishes may gain understanding. They reject authority, that is, the perfection of the mystery that is according to Christ: in order and in turn, fulfilling their shamelessness through the mysteries of angels. However, the term "glorious " (Δόξας) that is, splendors, is mentioned in both the Old and New Testaments: as Paul says, "For if what was brought to an end came with glory, much more will what is permanent have glory." (2 Cor. 3:11) And again: "For if the ministry of condemnation was glorious, much more will the ministry of righteousness abound in glory." (2 Cor. 3:9) Or it also refers to the ecclesiastical authorities, upon which they heap blasphemies: as can be learned even from the third Epistle of John the beloved, among whom he mentions Diotrephes, who gossiped against them with malicious words. (3 Jn. 10)”
