• Jude looks at grace. There is nothing like grace, but what if grace be abused? What if grace be abandoned? What if grace be turned to licentiousness? Now that is what Jude takes up. (“Jude 1” by W. Kelly)
• That which is peculiarly striking in the Epistle of Jude is that he pursues the corruption of the assembly from the creeping in of some unawares on to its final judgment, showing withal that it is not arrested but passes through its various phases to that day. (“JUDE” by J.N. Darby)
• Peter, as pointed out, it is sin-sin working indeed in gross forms-in the bosom of the Church; in Jude it is moral apostasy, though those who are guilty of it still retain their place inside (v. 12); while in John the apostates have gone out. "They went out from us, but they were not of us," etc. (1 John 2:19). (article #86561)
