Jude 1:20 - Coke's Commentary on the Holy Bible

But ye, beloved, &c.— The false teachers corrupted the faith, turned the grace of God into lasciviousness, and would have made parties, tearing in pieces the church of God. The Christians, therefore, both here and Jude 1:3; Jude 1:17 are exhorted to preserve one another through divine grace in that true, pure, unmixed faith, as it was taught them by the apostles of our Lord. Their faith was called most holy, as it did not lead to licentiousness, like the corrupt doctrine of the false teachers, but promoted the most holy tempers and conversation. See 2 Peter 2:21. The Christian faith, which makes Christ the All in All, is here considered as the foundation of a building, and they were to build up each other on that foundation, the architect style is often made use of in the New Testament. They were to pray in the Holy Ghost, and, by his influences vouchsafed in answer to their prayers, were to make swifter advances in the divine life. The false teachers were sensual, and had not the Spirit: most probably they had once had the Spirit, but by departing from the true faith, and falling into vice, they had quenched the Spirit, and it was withdrawn from them. But the true Christians, building up one another upon their most holy faith; that is, not having quenched the Spirit by departing from the truth, or falling into vice, were to assemble together frequently, and make use of their spiritual gifts.
