Jude 1:9

Verse 9. Yet Michael the archangel.

That it may plainly appear why you should ignore the false teachers in their attempts to seduce you from the path marked out for your career as Christians, I call to your attention the conduct imposed by the Father of Lights upon one even as mighty as an archangel even Michael. He dare not bring a railing accusation against the arch-enemy of man, the devil. He was required to leave even a rebuke of this most vile of all beings to the Lord. In the archangel's contention with the devil over the body of Moses, he simply said, "The Lord rebuke thee." So you Christians can easily perceive that the course pursued by these false teachers is not from on high. Should you follow such guides, you would be led away from Christ and from his glorious reward surely in store for the faithful.
