ISB ~ Revelation 2 v6

the Nicolaitans:Early tradition links these heretics with Nicolaus, one of the seven deacons ordained in Acts 6:5. Whatever their background and origin, the Nicolaitans are said to have had a dangerously casual attitude toward idolatry and sexual immorality. Their corruptive influence was already at work among believers in Pergamum (Rev 2:15).
