“For certain men are secretly entered in, (who were written of long ago unto this judgment,) ungodly men, turning the grace of our Lord God into riotousness, and denying the only sovereign Ruler, and our Lord Jesus Christ.”
“For certain men have entered unawares, ungodly men, who had been of old ordained and predestined to the judgment of our God;" not that they might become impious, but that, being now impious, they were ordained to judgment.”
“There are some godless men who twist Scripture wickedly and who have come into the church, pretending to preach the gospel. Their judgment was decreed long ago, and they have condemned themselves by their actions. As a result, they have been handed over to their impure lusts. By their great ungodliness they have turned the grace of our Lord Jesus Christ into wantonness, and by their wickedness even people who have been called by the gospel have denied the one Lord Jesus Christ. It is in order to win them back that Jude goes on to talk of what God did in the past to people who behaved in that way.”
“These words were written about those who, after attributing the glory of sonship only to the Word begotten of God the Father, say that another son of the seed of David and Jesse has been united with him and been given a share in the sonship and in the glory proper to God.”
“Jude means that their condemnation was predestined, for even the betrayal of Judas had been foretold. Here he is talking about the Simonians, for they are gluttonous and intemperate, pretending to teach godliness so that they can worm their way into people's houses.”
“Certain men have crept in, etc. He means into this judgment, into this condemnation, which the impious deserve by their actions. Hence the Lord says: And they shall come forth, those who have done good, to the resurrection of life; and those who have done evil, to the resurrection of judgment (John V), that is, condemnation.”
“Perverting the grace of our Lord into licentiousness. The grace of our Lord has softened the hardness of the law, because when it said, If anyone does this or that, let them be stoned; if anyone does this or that, let them be burned with fire; the Lord, having relaxed the strictness of the law, gave through the grace of the Gospel the license to purge committed crimes through penance and the fruits of almsgiving. But they pervert this grace of His into licentiousness, who now sin all the more freely and easily, as they see themselves less immediately examined by the harshness of the law for their admitted crimes.”
“And denying the only Sovereign and Lord, our Lord Jesus Christ. Our Lord Jesus Christ is the only Sovereign with the Father and the Holy Spirit, just as the Father is the only Sovereign with the Son and the Holy Spirit, and just as the Holy Spirit is the only Sovereign with the Father and the Son. The whole Trinity—Father, Son, and Holy Spirit—is the only Sovereign. For whichever person you name in the same holy and indivisible Trinity, it is the only God. And when you name the whole Trinity together, you name the only true God. Hence it is rightly understood that any heretics who deny that the Father of Christ is the true, good, and just God deny our only Sovereign and Lord. Whoever denies that Jesus Christ is the true Son of God, they also deny our only Sovereign and Lord. Whoever diminishes the power of the Holy Spirit, they also contradict the majesty of our only Sovereign and Lord, for the same Father, Son, and Holy Spirit is undeniably our only Sovereign and Lord.”
“He exhorts those who once acknowledged our Lord Jesus Christ as Savior and believed in Him, to contend for the faith. For if we have accepted the incarnate Word and yet say that He Who is from the Father before the ages is one, and He Who is from the Mother is another, and that He is a separate person, then how do we not deny the one Lord and Master? For the Lord Jesus is one by the union of the economy; because the pre-eternal Word of God and God, having flesh grafted into the glory of the Godhead, which He assumed from the Holy Virgin, from the very conception, is one and the same Master of all.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
