This is what Yahshua said to the ecclesia in Ephesus:
(CLV) Re 2:6
But this you have, that you are hating the acts of the Nicolaitans, which I, also, am hating.
Yahshua hates these acts! Strong words are these.
It's clear to me that I don't want to act like a Nicolaitan.
This is what Yahshua said to the ecclesia at Pergamum:
(CLV) Re 2:15
Thus you, also, have those holding the teaching of the Nicolaitans, likewise.
(CLV) Re 2:16
Repent then! Yet if not, I am coming to you swiftly and shall be battling with them with the blade of My mouth.
It's clear to me that I don't follow the teachings of the Nicolaitans.
Which leads me to the question, what are these teachings?
Let's take a look.
The doctrine of the Nicolaitans appears to have been a form of
antinomianism, which makes the fatal mistake that man can freely partake in sin because the Law of God is no longer binding.
Today, the doctrine is now largely taught that the gospel of Christ has made God's law of no effect: that by "believing" we are released from the necessity of being doers of the Word. But this is the doctrine of the Nicolaitans, which Christ so unsparingly condemned in the book of Revelation.
