to execute judgment on all, and to convict all the ungodly of all their deeds of ungodliness which they have committed in such an ungodly way, and of all the harsh things which ungodly sinners have spoken against him.”
ποιῆσαι κρίσιν κατὰ πάντων καὶ ἐλέγξαι πᾶσαν ψυχὴν περὶ πάντων τῶν ἔργων ἀσεβείας αὐτῶν ὧν ἠσέβησαν καὶ περὶ πάντων τῶν σκληρῶν ὧν ἐλάλησαν κατ’ αὐτοῦ ἁμαρτωλοὶ ἀσεβεῖς.
Haydock Catholic Bible Commentary: Jude
Nothing more terrible than a God avenging in the majesty of his power his own cause. Then the impious libertine, in proportion as he has studied to extinguish in himself and to stifle in others the light of faith, the more shall be confounded and overwhelmed with the glory of God in the day of just retribution.
