Preacheritis the doctrine of the Nicolaitanes
Revelation 2:6 But this thou hast, that thou hatest the deeds of the Nicolaitanes, which I also hate.
15 So hast thou also them that hold the doctrine of the Nicolaitanes, which thing I hate.
Nicolaitane, comes from two Greek words: Nikao which means to conquer, and Lao which means the laity. Nicolaitane means, "to conquer the laity." Now why is this such a terrible thing? It is terrible because God has never placed His church in the hands of an elected leadership which moves with political mindedness. He has placed His church in the care of God- ordained, Spirit-filled, Word-living men who lead the people through feeding them the Word.

The Nicolaitian doctrine is more widespread in the Church today than you may think. It may be more easily identified in the Catholic Church, which has a clear clergy/laity system. But it is just as prevalent in the protestant Church. It is a hidden thing which skillfully avoids the light. But if the truth is revealed to you, then you must follow Christ’s example and be against it.

When our Lord Jesus Christ walked among men, He taught His disciples to beware of the leaven of the Pharisees, whom He denounced as hypocrites. With them He classed the chief priests and officials of the temple, together with the recognized teachers, (scribes, or "professors" Ferrar Fenton Translation) in the Synagogues. He declared they had so corrupted the truth of God, which they were supposed to preach, with the doctrines and ordinances of men, that the truth, as originally given, was no longer with them. That which these blind leaders of the blind were giving forth as truth of God was making their converts twofold more the children of hell than they were before accepting the [schi]ism by these corrupt teachers.
