The church at Ephesus had them
Rev 2:6 But this thou hast, that thou hatest the deeds of the Nicolaitans, which I also hate.
So did the church at Pergamos:
Rev 2:14 But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught
Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication.
Rev 2:15 So hast thou also them that hold the doctrine of the Nicolaitans, which thing I hate. (KJV)
Even poor Thyratira:
Rev 2:20 Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself
a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols. (KJV)

Thus, the “Nicolaitans” are “rulers over the laity” as the politicians and priests love to do.
They have set up falsehood among the people, both in government and religion. It will take our true Ruler, Jesus Christ to
set things straight.
Jer 2:26 As the thief is ashamed when he is found, so is the house of Israel ashamed; they, their kings, their princes,
and their priests, and their prophets, (KJV)
Jer 2:27 Saying to a stock, Thou art my father; and to a stone, Thou hast brought me forth: for they have turned their
back unto me, and not their face: but in the time of their trouble they will say, Arise, and save us. (KJV)
Ezek 22:26 Her priests have done violence to my law, and have profaned my holy things: they have made no distinction between
the holy and the common, neither have they caused men to discern between the unclean and the clean, and have hid their eyes
from my sabbaths, and I am profaned among them. (ASV)
Ezek 22:27 Her princes in the midst thereof are like wolves ravening the prey, to shed blood, and to destroy souls, to
get dishonest gain. (KJV)
Ezek 22:28 And her prophets have daubed them with untempered morter, seeing vanity, and divining lies unto them, saying,
Thus saith the Lord GOD, when the LORD hath not spoken. (KJV)
Ezek 22:29 The people of the land have used oppression, and exercised robbery, and have vexed the poor and needy: yea,
they have oppressed the stranger wrongfully. (KJV)
Micah 3:11 The heads thereof judge for reward, and the priests thereof teach for hire, and the prophets thereof divine
for money: yet will they lean upon the LORD, and say, Is not the LORD among us? none evil can come upon us. (KJV)
