The letter to Jude warned against those who, having gained admission to the church, were perverting the grace of God, denying “our only Master and Lord, Jesus Christ” (v4). Jude used Old Testament examples to warn of these “blemishes” on the church. He wrote multiple dnunciations of these ungodly people who “defile the flesh” and “reject authority” (v.8). In contrasts, he urged Christians to continue in godliness and love toward such people, convincing some, “snatching them out of the fire” (vv. 22-23). The book of Jude closes with one of the most beautiful doxologies in all of Scripture (vv 24-25). Jude was probably the half brother of Jesus Christ and the brother of James Jude likely wrote in about A.D. 69.
