For there are certain men (see the margin) crept in unawares Insinuating themselves into people's affections by their plausible pretences, and leavening them by degrees with their errors. The ungodly teachers here described seem to have been the Nicolaitans, mentioned Revelation 2:6, whose doctrine Christ himself declared to be hateful to him. Perhaps the Gnostics and Carpocratians, the successors of the Nicolaitans, were also meant. The Nicolaitans are said to have maintained that marriage was a human invention, not binding on Christians; on which account they had women in common, and practised unnatural lusts, as is plain from Jude's account of them. And they hardened themselves against the fear of punishment in a future state for these crimes, by extolling the goodness and mercy of God, which they thus perverted to lasciviousness. Who were of old ordained Or rather, as the original expression, προγεγραμμενοι
εις τουτο το κριμα, literally signifies, written, or described, before to this condemnation Even as early as Enoch, by whom it was foretold, that by their wilful sins they would incur this condemnation. “Jude means, that these wicked teachers had their punishment before written, that is, foretold, in what is written concerning the wicked Sodomites and rebellious Israelites, whose crimes were the same with theirs; and whose punishment was not only a proof of God's resolution to punish sinners, but an example of the punishment which he would inflict on them. Others think that in the word προγεγραμμενοι, written before, there is an allusion to the ancient custom of writing laws on tables, which were hung up in public places, that the people might know the punishment annexed to the breaking of the laws. If this is the allusion, the apostle's meaning will be, that the wicked teachers, of whom he is speaking, were, by the divine law, condemned to severe punishment from the beginning. Turning the grace of our God Revealed in the gospel; into lasciviousness Into an occasion of more abandoned wickedness, even to countenance their lewd and filthy practices. It seems these ungodly men interpreted the doctrine of justification by faith, in such a manner as to free believers from all obligation to obey the law of God, and taught that they might commit the worst actions without being liable to punishment, if they possessed faith; by which they meant the mere speculative belief and outward profession of the gospel. Denying the only Lord God, and our Lord Jesus Christ See on 2 Peter 2:1. The original words, και τον μονον δεσποτην Θεον και κυριον ημων Ιησουν Χριστον αρνουμενοι, “may be translated various ways, all equally literal: 1st, And denying the only Lord God, even our Lord Jesus Christ. According to this translation, one person only is spoken of here, namely, our Lord Jesus Christ, who is called the only Lord God. 2d, Denying both the only Lord God, and our Lord Jesus Christ. According to this translation, two persons are distinctly spoken of, namely, the one Lord God, or God the Father, and our Lord Jesus Christ his Song of Song of Solomon 3 d, And denying the only Lord God, and our Lord Jesus Christ. This, which is the translation in our English Bible, and which, in sense, is not different from the second rendering, I have adopted,” says Macknight, “not only because, according to it, two persons are spoken of as denied, namely, the only Lord God, and our Lord Jesus Christ, but because it represents Jude's sentiment as precisely the same with John's 1st epist. 1 John 2:22, He is the antichrist who denieth the Father and the Son. By declaring that those ungodly teachers denied both the Father and the Son, the apostle showed to what a pitch of impiety they had proceeded.
