Whereas angels, who are greater in power and might, bring not railing accusation against them before the Lord.
Read Chapter 2
Cyprian of Carthage
AD 258
Of this same thing in the Epistle of Peter: "As strangers and pilgrims, abstain from fleshly lusts, which war against the soul; but having a good conversation among the Gentiles, that while they detract from you as if from evildoers, yet, beholding your good works, they may magnify God."
Whereas angels By comparing this place with what we read in St. Jude, (ver. 9) he speaks of the good angels whom God employed to banish the rebellious angels out of heaven, and on other occasions, who, though they had greater strength and power given them by the Almighty, yet did not bear execrable judgment against themselves; i.e. one against another, or against those who at first had been happy spirits with them in heaven; did not exult over them with injuries and reviling reflections, but executed their commands in the name of God, saying, let the Lord command you. See Jude, ver. 9. (Witham)
Bring not an execrable judgment That is, they use no railing, nor cursing sentence; not even in their conflicts with the evil angels. (Challoner)
