Revelation 2:6 - Coke's Commentary on the Holy Bible

The deeds of the Nicolaitans,— Some have thought that these heretics derive their name from Nicolas, one of the seven deacons; but that name was so common among the Jews, that no stress can be laid on an argument drawn from thence. The substance of what ancient writers say concerning them is, that they taught the lawfulness of lewdness, and idolatroussacrifices, esteeming those things indifferent in their own nature; and that their practices were suitable to such principles. See Revelation 2:14-15. 1 John 1:3; 1 John 1:10.
