Holier Than Thou

Who wrote the books of the Bible and when?

Epistle of Jude, a general letter to Jewish Christians, was written some time between 65 and 70 A.D. by Jude, a brother of Jesus and James. Some, including the Catholic Church, maintain that Jude is one of the original apostles of Jesus, a variant name of Judas son of James (Luke 6:16, Acts 1:13) and Thaddaeus (Matthew 10:3, Mark 3:18), although Jude doesn't seem to include himself as one of the original "Twelve" (Jude 17-18). Jude's main concern was false doctrine and the evil men who promoted it. The Epistle of Jude includes:

Warning of men who have slipped into the church to twist the gospel for their own wicked gain
Biblical examples of God's punishment on such evil doers
Even angels don't slander
Enoch's prophecy of these false teachers
Scoffers in the last times
Showing mercy on those who doubt
Praise to God (doxology)

Though you already know all this, I want to remind you that the Lord delivered his people out of Egypt, but later destroyed those who did not believe. And the angels who did not keep their positions of authority but abandoned their own home -- these he has kept in darkness, bound with everlasting chains for judgment on the great Day. In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire.
In the very same way, these dreamers pollute their own bodies, reject authority and slander celestial beings. But even the archangel Michael, when he was disputing with the devil about the body of Moses, did not dare to bring a slanderous accusation against him, but said, "The Lord rebuke you!" Yet these men speak abusively against whatever they do not understand; and what things they do understand by instinct, like unreasoning animals -- these are the very things that destroy them.
Woe to them! They have taken the way of Cain; they have rushed for profit into Balaam's error; they have been destroyed in Korah's rebellion. (Jude 5-11)
