Revelation 2:6 sn The Nicolaitans were a sect that apparently taught that Christians could engage in immoral behavior with impunity. They are also mentioned in 2:15. They are sometimes associated with Nicolaus, one of the seven original deacons in the church in Jerusalem according to Acts 6:5. The early church father Irenaeus connected them to Nicolaus and further described them as an immoral Gnostic sect (Adv. Haer. 1.26.3; 3.11.1). It is unclear however if the association of the Nicolaitans with the Nicolaus of Acts 6:5 is correct as this view may have arisen based on simple name identification rather than a real historical connection. It is also possible that the group adopted the name of Nicolaus to give them credibility (Eusebius, Eccl. Hist. 3.29.1).
Revelation 2:6 tn The expression τὰ ἔργα τῶν Νικολαϊτῶν (ta erga tōn Nikolaitōn) has been translated as a subjective genitive.
