Nicolaitans (nĭk-o-lâ'i-tanz). Heretical persons or teachers, mentioned in Revelation 2:6; Revelation 2:15. Compare 2 Peter 2:12; 2 Peter 2:19; Judges 1:4; Judges 1:7-8; Judges 1:11-12. Some suppose them to have been followers of Nicolas the deacon, but there is no good evidence that he ever became a heretic.
