Nicolaitans

The Nicolaitans were a sect condemned by the risen Christ in messages to two of the seven churches of Asia in Revelation — Ephesus, which hated their works (Rev. 2:6), and Pergamum, where some held their teaching (Rev. 2:15). Their deeds are linked to the "teaching of Balaam" — eating food sacrificed to idols and practicing sexual immorality — suggesting they advocated accommodation to pagan culture that the church's Jerusalem decree had explicitly prohibited (Acts 15:20, 29).

Early church fathers (Irenaeus, Clement of Alexandria) attributed the sect's founding to Nicolaus, one of the seven deacons of Acts 6:5, though this attribution is disputed and may reflect a later invention of etymology. The precise nature of their teaching is uncertain; some scholars see them as proto-Gnostics who separated spirit and flesh and thus considered physical conduct morally irrelevant. Their name may be a Greek equivalent of the Hebrew name Balaam (both meaning "conqueror of the people"), making the Balaam connection in Revelation a deliberate wordplay.
