The epistle of Jude warns us that Korah's rebellion will occur in the last days. There will be Christians who say that the priesthood of all believers should replace ministerial functions in Christ's church.
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 1:10-11 (NIV)
This is the same rebellious spirit that has possessed many evangelical churches who profess a gospel of easy believism and an anti-authoritarian message that promotes denominational division. The epistle of Jude warns the New Testament church that Korah's rebellion will occur again. The priesthood of all believers will once again attempt to usurp the authority of God's ministers.
