Jude in our reading adds to the voices of Peter, Paul, and John in their latter letters, beware of the danger that exists within the church. Jude reminds his brethren and us that the truth had been established “once for all” but there will always be those that will come into the church and teach false doctrine. As Peter also noted, the danger they pose comes both from the doctrines they teach and from the influence of the sinful lives they live! Jude declares that the Lord will judge them, but the Lord’s church must be on guard at all times to stand against this ever present danger!
“In a culture that is increasingly apathetic or even antagonistic toward the Christian faith, in an era when pluralism and acceptance are the only ultimate virtues, we need to hear Jude’s reminder that there are times the faith must be defended. In Jude’s day as well as our own, that defense calls us to oppose false teaching, to live lives of faith and love, to pray in the Spirit, and to save those who falter.” (College Press)
