The New Testament Book of Jude

The church must contend for the one true faith once for all delivered to the saints, and people of faith must persevere to the end by resisting the false teachers and following the truth. Jude warns against following those who have surreptitiously gained entry to the church and are perverting the one true faith with false teaching. Indeed, the letter warns against allowing the false teachers to continue to have influence. Jude calls the church to defend the truth aggressively against this infiltration.
