Revelation 2:6

He says, nevertheless, you have this in your favor, that you hate the works of the Nicolaitans, which I also hate. He placed the fault of the two achievements in the middle, so that from the praises at the extremes, he might console the blame …

But this thou hast, that thou hatest the deeds of the Nicolaites, which I also hate. As if the universal angel were told, "Not in the species that I have just frightened, but in another one, thou hast this, that thou hatest the deeds of …

It is not possible for any to recover the first love, but by taking these three steps, 1. Remember from whence thou art fallen - From what degree of faith, love, holiness, though perhaps insensibly. And repent - Which in the very lowest sense implies a deep and lively conviction of thy fall.

But this thou hast, that thou hatest the deeds of the Nicolaitans,....

(2.) He was dead and is alive. He was dead, and died for our sins; he is alive, for he rose again for our justification, and he ever lives to make intercession for us. He was dead, and by dying purchased salvation for us; he is alive, and by his life applies this salvation to us.

The deeds of the Nicolaitanes - These were, as is commonly supposed, a sect of the Gnostics, who taught the most impure doctrines, and followed the most impure practices. They are also supposed to have derived their origin from Nicolas, one of the seven deacons mentioned Act 6:5 (note). The Nicolaitanes taught the community of wives, that adultery and fornication were things indifferent, that eating meats offered to idols was quite lawful; and mixed several pagan rites with the Christian ceremonies. Augustine, Irenaeus, Clemens Alexandrinus, and Tertullian, have spoken largely concerning them.

MICHAELIS' view is probable: Nicolaos (conqueror of the people) is the Greek version of Balaam, from Hebrew "Belang Am," "Destroyer of the people." Revelation abounds in such duplicate Hebrew and Greek names: as Apollyon, Abaddon: Devil, Satan: Yea (Greek, "Nai"), Amen. The name, like other names, Egypt, Babylon, Sodom, is symbolic.

But this thou hast - This thou hast that I approve of, or that I can commend. That thou hatest the deeds of the Nicolaitans - Greek, “works” (τὰ ἔργα ta erga). The word “Nicolaitanes” occurs only in this place, and in the Rev 2:15 verse of this chapter. From the reference in the latter place it is clear that the doctrines which they held prevailed at Pergamos as well as at Ephesus; but from neither place can anything now be inferred in regard to the nature of their doctrines or their practices, unless it be supposed that they held the same doctrine that was taught by Balaam. See the notes on Rev 2:15. From the two passages, compared with each other, it would seem that they were alike corrupt in doctrine and in practice, for in the passage before us their deeds are mentioned, and in Rev 2:15 their doctrine. Various conjectures, however, have been formed respecting this class of people, and the reasons why the name was given to them: I. In regard to the origin of the name, there have been three opinions: (1) That mentioned by Irenaeus, and by some of the other fathers, that the name was derived from Nicolas, one of the deacons ordained at Antioch, Act 6:5. Of those who have held this opinion, some have supposed that it was given to them because he became apostate and was the founder of the sect, and others because they assumed his name, in order to give the greater credit to their doctrine. But neither of these suppositions rests on any certain evidence, and beth are destitute of probability. […]
