But you, beloved, build yourselves up on your most holy faith; pray in the Holy Spirit;
Ὑμεῖς δέ, ἀγαπητοί, ἐποικοδομοῦντες ἑαυτοὺς τῇ ἁγιωτάτῃ ὑμῶν πίστει, ἐν πνεύματι ἁγίῳ προσευχόμενοι,
Haydock Catholic Bible Commentary: Jude
Building yourselves. That is, raising by your actions a spiritual building, founded 1. upon faith; 2. on the love of God; 3. upon hope, whilst you are awaiting for the mercies of God, and the reward of eternal life; 4. joined with the great duty of prayer. Wi.
