Charles Spurgeon Commentary Jude 1:8

"Yet in like manner these also in their dreamings defile the flesh, and set at nought dominion, and rail at dignities." — Jude 1:8 (ASV)

Likewise also these filthy dreamers defile the flesh, despise dominion, and speak evil of dignities.

What a strange thing it is that such evils should spring up in the nominal church of God! I suppose that, out of the professing church, there have come more monstrous evils than have been nursed in the world itself. Why, even in these days, we have had those who have professed perfection, who have given themselves over to abominable evils, and who have even taught them as a part of their perfection! Ah, me! To what depths of infamy will not men go!

Under the very guise of holiness, the most loathsome iniquity has been practiced. Unless the grace of God prevent, that which is best rots into that which is worst. You could not make a devil except with an angel for the raw material; a Judas Iscariot could only be produced out of an apostle of Jesus Christ; and it was into the nominal church of God that these filthy dreamers of whom Jude wrote had come. They were also, according to the apostle, those who despise dominion, and speak evil of dignities, those who quibble over everything that is right and good, and seek to pull down everything that comes to them with authority, especially everything that is of divine authority.
