Who are the Nicolaitans?
When Jesus 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 the temple officials, together with teachers in the synagogues. He declared that they had so corrupted the truth of God with the doctrines of men (the same sin as the Nicolaitans) that the truth, as originally given, was no longer with them. That which these blind leaders of the blind were giving forth as truth was making their converts more the children of hell than they were. The deeds of these false teachers are in the second chapter of Revelation. It states "To the angel of the church of Ephesus write, 'These things says He who holds the seven stars in His right hand, who walks in the midst of the seven golden lampstands . . . But this you have, that you hate the deeds of the Nicolaitans, which I also hate." (Revelation 2:1, 6)
The doctrines taught by these false teachers are in Revelation's letter to the church in Pergamos: "And to the angel of the church in Pergamos write, 'These things says He who has the sharp two-edged sword . . . Thus you also have those who hold the doctrine of the Nicolaitans, which thing I hate.' " (Revelation 2:12, 15)
The Lord not only demands repentance from those who believe and practice the 'doctrine of the Nicolaitans' but also threatens severe punishment if they do not obey: "Remember therefore from where you have fallen; repent and do the first works, or else I will come to you quickly and remove your lampstand from its place - unless you repent." (Revelation 2:5).
Greek meaning of word
The Greek word for Nicolaitans (Strong's Concordance Number #G3531) found in Revelation is actually three words combined. As a proper noun, it TRANSFERS, but is not translated, into English. The three Greek words used are Nikos, Laos and Ton.
The first Greek part of the English word Nicolaitans is NIKOS. We use the English equivalents instead of the Greek letters, as we shall also of the other two. Nikos is defined as "a conquest, victory, triumph, the conquered and by implication, those who are dominate over the defeated." Another transferred name in which this word is used is Nicopolis. It is composed of Niko, which means conquest, and polis, which means city. Nicopolis therefore means the city of conquest, or city of victory.
